1.3 SITING AND EXPOSURE
CAUTION: If any part of the weather
station comes in contact with power lines,
you could be killed. Contact local utilities
for the location of buried utility lines before
digging or driving ground rods.
Selecting an appropriate site for the weather
station is critical in order to obtain accurate
meteorological data. In general, the site should
be representative of the general area of interest,
and away from the influence of obstructions
such as buildings and trees.
The weather station should not be located
where sprinkler irrigation water will strike
sensors or instrument enclosure.
1.3.1 WIND SPEED AND DIRECTION
Wind sensors should be located over open level
terrain, and at a distance of at least ten times
(EPA) the height of any nearby building, tree or
other obstruction, as illustrated in Figure 1.3-1.
Standard measurement heights:
3.0 m ± 0.1 m recommended (AASC)
2.0 m ± 0.1 m, 10.0 m ± 0.5 m optional (AASC)
10.0 m (WMO and EPA)
1.3.2 TEMPERATURE AND RELATIVE
HUMIDITY
Sensors should be located over an open level
area at least 9 m (EPA) in diameter. The
surface should be covered by short grass, or
where grass does not grow, the natural earth
surface. Sensors should be located at a
distance of at least four times the height of any
nearby obstruction and at least 30 m (EPA)
from large paved areas. Sensors should be
protected from thermal radiation, and
adequately ventilated.
Situations to avoid include:
• large industrial heat sources
• rooftops
• steep slopes
• sheltered hollows
• high vegetation
• shaded areas
• swamps
• areas where snow drifts occur
• low places holding standing water after
rains
Standard measurement heights:
1.5 m ± 1.0 m (AASC)
1.25 - 2.0 m (WMO)
2.0 m temperature (EPA)
2.0 m and 10.0 m for temperature difference
(EPA)
1.3.3 PRECIPITATION
A rain gage should be sited on level ground that
is covered with short grass or gravel. In open
areas, the distance to obstructions should be
two to four times (EPA, AASC) the height of the
obstruction.
Some general guidelines for site selection are
listed below, which were condensed from EPA
(1988)
1
, WMO (1983)2, and AASC (1985)
3
publications.
The height of the opening should be as low as
possible, but should be high enough to avoid
splashing from the ground. Wind shields, such
as those used by the National Weather Service,
are recommended for open areas.
1-3
SECTION 1. PREPARATION AND SITING
Collectors should be heated, if necessary, to
properly measure frozen precipitation. The
gage must be mounted above the average level
of snow accumulation in areas that experience
significant snowfall.
Standard measurement heights:
1.0 m ± 1.0 cm (AASC)
30.0 cm minimum (WMO, EPA)
1.3.4 SOLAR RADIATION
Pyranometers should be located to avoid
shadows on the sensor at any time. Mounting it
on the southern most (northern hemisphere)
portion of the weather station will minimize the
chance of shading from other weather station
structures. Reflective surfaces and sources of
artificial radiation should be avoided. The height
at which the sensor is mounted is not critical.
1.3.5 SOIL TEMPERATURE
The measurement site for soil temperature should
2
be at least 1 m
and typical of the surface of
interest. The ground surface should be level with
respect to the immediate area (10 m radius).
Standard measurement depths:
10.0 cm ± 1.0 cm (AASC)
5.0 cm, 10.0 cm, 50.0 cm, 100.0 cm (WMO)

SECTION 1. PREPARATION AND SITING
1.4 DETERMINING TRUE NORTH FOR
WIND VANE ORIENTATION
Magnetic declination, or other methods to find True
North, should be determined prior to installing the
weather station. True North is usually found by
reading a magnetic compass and applying the
correction for magnetic declination*; where
magnetic declination is the number of degrees
between True North and Magnetic North. Magnetic
declination for a specific site can be obtained from a
USFA map, local airport, or through an internet
service called NSSDC CGM (Section 1.4.1). A
general map showing magnetic declination for the
contiguous United States is shown in Figure 1.4-1.
Subtract declination from 360°Add declination to 0°
22 E
20 E
18 E
16 E
14 E
12 E
10 E
Declination angles east of True North are
considered negative, and are subtracted from 0
degrees to get True North as shown Figure 1.4-2.
Declination angles west of True North are considered positive, and are added to 0 degrees to get
True North as shown in Figure 1.4-3. For
example, the declination for Logan, Utah is 14.5°
East. True North is 360° - 14.5°, or 345.5° as read
on a compass.

SECTION 1. PREPARATION AND SITING
1.4.1 NSSDC CGM SERVICE
The NSSDC CGM (Corrected Geomagnetic)
Service provides an easy way of determining
magnetic declination of a specific site. Since
magnetic declination fluctuates with time, it
should be determined each time the wind vane
orientation is adjusted. It can be accessed on
the world wide web at
http://nssdc.gsfc.nasa.gov/space/cgm/cgm.html
If you know the latitude and longitude of your
site, fill out Form 1as shown below for an
accurate magnetic declination. If you do not
know the latitude and longitude of your site, fill
out Form 2 for estimate of magnetic declination.
Note that longitude is expressed in 0 to 360
degrees east of the Greenwich prime meridian,
and that north latitudes are positive.

Magnetic declination is bold in this example to
show its location in the table. A positive
declination is east, while a negative declination
is west. The declination in this example is
14.417 degrees. As shown in Figure 1.4-1, the
declination for Logan, UT is east, so True North
for this site is 360 - 14.417, or 345.5 degrees.

2.3 TRIPOD INSTALLATION
CM6 and CM10 tripods are designed to allow
installation in many types of terrain. The
following installation instructions, however,
assume an installation on flat and reasonably
level ground.
1. Prepare the area where the tripod will be
installed. In most installations, the tripod
requires an area 9 feet (CM6) or 12 feet
(CM10) in diameter. Natural vegetation and
the ground surface should be disturbed as
little as possible, but brush and tall weeds
should be removed.
SECTION 2. TRIPOD INSTALLATION
2. Lay the tripod base and mast assemblies
on the ground. Apply pipe dope or Teflon
tape to threads on the crossarm mount
(short pipe) and the 1 1/4 inch end of the
mast. To prevent cross-threading, hand
thread the crossarm mount into the mast’s
bell reducer and then tighten with a pipe
wrench. Hand thread the mast into the
threaded coupling on the tripod center
bracket and then tighten with a pipe wrench.
3. Using a tape measure and a felt-tipped pen,
mark the tripod legs to indicate how far they
should extend. From the end of the 3/4”
pipe that attaches to the foot (Figure 2-2),
measure up 23” on the CM10, or 26” on the
CM6, and mark each leg with a felt tip pen.
4. Each leg has a slide collar with a single bolt
for loosening or tightening the collar (Figure
2-2). Loosen the bolt on each collar with a
1/2” wrench.
FIGURE 2-2. Extending the Tripod Legs
5. Stand the tripod upright and orient it so one
leg points south (Figure 2-3). Extend the
leg until the top of the slide collar is even
with the mark from Step 3 and tighten the
bolt. Extend the other legs in the same
manner.
6. Plumb the mast by adjusting the south and
northeast facing legs. Loosen the slidecollar bolt on the south facing leg. With the
level on the south side of the mast, adjust
the leg so the level reads plumb, then
tighten the bolt. Repeat the same
procedure for the northeast facing leg with
the level on the east side of the mast.
NOTE: Adjusting the legs can be made
easier by spraying the slide collar and leg
with a silicon spray, and tapping on the leg
with a hammer.
7. Three rebar stakes are provided for
securing the tripod to the ground. Drive the
stakes through the holes in the feet. Some
users prefer to drive 4 foot “T” posts next to
each leg, and attach the legs to the posts
with 2” u-bolts.
2-3
SECTION 2. TRIPOD INSTALLATION
FIGURE 2-3. Tripod and Component Orientation
2.4 TRIPOD GROUNDING
Ground the tripod and shown in Figures 2-1,
2-4, and 2-5.
1. Drive the ground rod close to the center of
the tripod using a fence post driver or
sledge hammer. Slide the clamp down the
rod before driving it in the ground. This will
eliminate the frustration of trying to get the
clamp to fit over a hammer damaged rod
end. Drive the rod at an angle if an
impenetrable hardpan layer exists. In hard
clay soils, a gallon jug of water can be used
to “prime” the soil and hole to make driving
the rod easier.
2. Loosen the bolt that attaches the clamp to
the ground rod. Strip 1 inch of insulation
from one end of the 4 AWG wire and insert
it between the rod and the clamp. Tighten
the clamp bolt (Figure 2-4).

SECTION 2. TRIPOD INSTALLATION
3. Loosen the set screws in the two brass
ground lugs attached to the center bracket
of the tripod (Figure 2-5). Strip 1 inch of
insulation from the other end of the 4 AWG
wire and insert it into the lower ground lug.
Tighten the set screw. Strip 1 inch of
insulation from one end of the 12 AWG wire
and insert it into the upper ground lug.
Tighten the set screw. The other end of the
12 AWG wire will attach to the ground lug of
the instrumentation enclosure.
4. Attach the lightning rod to the mast as
shown in Figure 2-1. If the weather station
includes an 019ALU crossarm, attach it to
the mast first, as described in Section
2.2-1 of the weather station installation
manual. Loosen the two screws on the
lightning rod mounting bracket. Position the
mounting bracket 4 inches down from the
top of the mast, then tighten both screws
evenly. Make sure the lightning rod set
screw is tight.
The CM10 Guy Kit is an option when
purchasing the CM10 Tripod or CM10K Tripod
Kit. It can be installed to improve the CM10
Tripod wind load rating. Table 2-3 lists items in
the CM10 Guy Kit.
FIGURE 2-6. Guy Wire Installation
1. Construct an assembly consisting of the top
plate, wire ropes, 3 thimbles, and 6 u-bolts.
a. Place a thimble into each of the three
small holes of the top plate. Twist each
thimble slightly, as shown in Figure 2-7,
to accomplish this.
b. Thread a piece of wire rope through
each of the three small top plate holes.
Double the wire rope back on itself
about 8 inches. Clamp the doubled
wire with two u-bolts per wire, forming a
loop. Fit the wire loop into the thimble
groove. Adjust the u-bolts as needed.
Once the thimble and wire loop are
fitted together, tighten the u-bolts to
secure the clamps.
2-5
SECTION 2. TRIPOD INSTALLATION
FIGURE 2-7. Thimble Twisting
2. Slide the top plate down the crossarm
mount so that it rests on the bell reducer.
3. Attach the 3 bottom plates to the tripod feet
with the existing tripod foot bolts. Make
certain that each bottom plate is oriented
such that the second hole is above the
tripod foot.
7. Sequentially pull the free end of the wire
ropes to tighten each turnbuckle loop.
When each is as hand tight as possible,
tighten the u-bolts to secure the clamps.
8. Tighten the turnbuckles sequentially, one
turn per cycle. Only tighten the turnbuckles
until the wire rope is taught. DO NOT
OVER TIGHTEN! The turnbuckles and
wire rope are strong enough to buckle the
mast if over tightened.
9. Check plumbness of the mast and adjust
the guy wire tightness as needed.
2.6 SENSOR MOUNTING BRACKETS
Mounting brackets provide a means of mounting
the sensors to the tripod. Bracket mounting
heights are referenced from the top of the bell
reducer; orientation is shown in Figure 2-3.
4. Extend each turnbuckle to its functional limit
5. Attach the loop-end of the turnbuckles to
the free end of each wire rope as shown in
Figure 2-8. Use the remaining thimbles and
u-bolts as done in step 1. Only fingertighten the u-bolts, however.
2.6.1 019ALU CROSSARM SENSOR MOUNT
Attach the 019ALU to the mast as shown in
Figure 2-9.
Slide the center NU-RAIL connector of the
019ALU down the crossarm mount (short pipe)
until it rests on top of the bell reducer. In most
applications, the center of the NU-RAIL
connector should be about 113" above the
ground surface. Orient the 019ALU in a
East/West direction with the 3/4" NU-RAIL
facing East (northern hemisphere) and tighten
the set screws. If the 025 Crossarm Stand is
used (Section 2.6.4), orient the 019ALU NorthSouth with the 3/4" NU-RAIL facing South.

3.3.6 MD9 MULTIDROP INTERFACE
The MD9 Multidrop Interface enables
communication with one or more
MetData1s/dataloggers and the computer over
a single 75 ohm coaxial cable. An MD9 network
can be connected directly to a PC, or can be
connected to a telephone modem (refer to the
MD9 Manual) and accessed remotely.
Total coax length may be up to three miles.
Since each MD9 attenuates the signal 0.2 db,
the maximum length depends on the number of
MD9s in the network (refer to the MD9 manual).
Coaxial cable and BNC connectors may be
ordered from CSI, or purchased locally (Belden
Type 9100 RG59/U or equivalent). Call Belden
Wire and Cable at (317) 983-5200 for the name
of a local distributor.
Installation requirements depend on the type of
cable that is used, and how it is installed (direct
burial, conduit, etc.). In general, follow state
and local electrical codes.

REFLECTOMETER
Probe rods can be inserted vertically or
horizontally into the soil surface, as shown in
Figure 4.16-1, or buried at any orientation to the
surface. A probe inserted vertically into a soil
surface will give an indication of the water
content in the upper 30 cm of soil. Horizontal
installation will detect the passing of wetting
fronts. Insertion at a 30 degree angle with the
surface will measure water content in the upper
15 cm of soil.
Probes must be inserted such that no air voids
are created around the rods, and that the rods
remain as parallel as possible. Use the
CS615G probe insertion guide to minimize
errors due to improper insertion.
The standard calibration for the CS615 probe,
as programmed in Short Cut, is valid for loamy
soils with low organic content. In other types of
SR50
soils, reporting the output in units of period will
make it possible to apply your own calibration
during post processing of data.

sensor response. Always install a wet
sensor.
2. Install the sensor into soil representative of
the field conditions you wish to monitor.
Avoid high or low spots. Placement south
of the weather station mast (northern
hemisphere) will avoid the effects of the
mast shade. Installation in the root zone is
best if measurements are used for irrigation
purposes.
3. The 257 should be removed from the soil
prior to harvest or cultivation operations to
avoid damaging the sensor or sensor cable.

site can be obtained from a USFA map, local
airport, or through a computer service offered by
the USFS called GEOMAG (Section 4.20.2). A
general map showing magnetic declination for the
contiguous United States is shown in Figure 4.20-1.
Declination angles east of True North are
considered negative, and are subtracted from 0
degrees to get True North as shown Figure 4.20-2.
Declination angles west of True North are considered positive, and are added to 0 degrees to get
True North as shown in Figure 4.20-3. For
example, the declination for Logan, Utah is 16°
East. True North is 360° - 16°, or 344° as read on
a compass.
Orientation is most easily done with two people,
one to aim and adjust the sensor, while the
other observes the wind direction displayed by
the datalogger.
1. Establish a reference point on the horizon for
True North.
2. Sighting down the instrument center line, aim

SECTION 5. METDATA1 SOFTWARE INSTALLATION
Software required for the METDATA1 consists of the datalogger program and a datalogger support
software suite for Windows or MS-DOS.
5.1 DATALOGGER PROGRAM
The datalogger program operates the
MetData1. It programs the MetData1 to
measure sensors, process the measurements,
and store data in the datalogger’s memory. The
datalogger program is created using Short Cut
for MS-DOS. It is compatible with Windows
DOS emulator. A separate manual covers the
use of Short Cut in detail.
5.2 DATALOGGER SUPPORT SUITE
A datalogger support software suite, either
PC208W or PC208, enables interfacing with the
MetData1 through Windows or MS-DOS.
Follow the installation procedure outlined in the
front of the software manual. PC208(W) is
used to download programs to the MetData1. It
is also used to monitor data in real time and
retrieve data stored in the MetData1.

SECTION 6. MAINTENANCE AND TROUBLESHOOTING
These guidelines apply to several different Campbell Scientific weather stations.
6.1 MAINTENANCE
Proper maintenance of weather station
components is essential to obtain accurate
data. Equipment must be in good operating
condition, which requires a program of regular
inspection and maintenance. Routine and
simple maintenance can be accomplished by
the person in charge of the weather station.
More difficult maintenance such as sensor
calibration, sensor performance testing (i.e.,
bearing torque), and sensor component
replacement, generally requires a skilled
technician, or that the instrument be sent to
Campbell Scientific or the manufacturer.
A station log should be maintained for each
weather station that includes serial numbers,
dates that the site was visited, and maintenance
that was performed.
6.1.1 INSTRUMENTATION MAINTENANCE
The instrumentation requires a minimum of
routine maintenance. A few preventative
maintenance steps will optimize battery life and
decrease the chances of datalogger failure.
6.1.2 BATTERIES
solar panel at all times. The charge indicating
diode should be "ON" when voltage to the
charging circuitry is present. Be aware of
battery voltage that consistently decreases over
time, which indicates a failure in the charging
circuitry.
6.1.3 DESICCANT
Enclosure humidity is monitored in the ET
Enclosure and MetData1 systems by an RH
chip incorporated into the connector board.
Change the desiccant packs when the
enclosure RH exceeds 35%. The RH chip
should be changed every 3 to 5 years.
In standard weather stations, a humidity
indicator card is provided with the enclosure. A
small RH sensor (10162) can be purchased
separately to record the RH inside the
enclosure. Change the desiccant when either
the card or the sensor read about 35% RH.
Desiccant may be ordered through Campbell
Scientific (DSC 20/4).
Desiccant packs inside of the dataloggers do not
require replacement under normal conditions.
Instruction 10 can be used to measure battery
voltage. By recording battery voltage the user
can determine how long a fresh set of batteries
will last (see the Installation Section of the
datalogger Operator's Manual for cold
temperature effects on alkaline batteries).
Short Cut and ETPro automatically program the
weather station to measure battery voltage.
When alkaline batteries are used, the battery
voltage should not be allowed to drop below 9.6
VDC before replacement. Where CR10 or 21X
dataloggers are used in the instrumentation, an
external battery must be used to maintain power
to the datalogger when changing batteries,
otherwise the clock, program, and data will be
lost (refer to the Installation Section of the
datalogger's Operator's Manual for details).
When not in use, remove the eight cells to
eliminate potential corrosion of the contact
points, and store in a cool dry place.
Rechargeable power supplies should be
connected to an AC transformer or unregulated
6.1.4 SENSOR MAINTENANCE
Sensor maintenance should be performed at
regular intervals, depending on the desired
accuracy and the conditions of use. A suggested
maintenance schedule is outlined below.
1 week
• Check the pyranometer for level and
contamination. Gently clean, if needed.
• Visually inspect the wind sensors and
radiation shield.
