RAWS-F Remote Automated Weather Station for Fire Weather
1. Introduction
The RAWS-F Fire Weather Quick Deployment Station is a lightweight, pre­configured station that can be set up in less than 10 minutes—without tools (see Section 2, Getting Started). The aluminum environmental enclosure houses a 12 V rechargeable battery and a CR1000 datalogger mounted to a 6 ft tripod. The outside of the enclosure has color-coded, keyed connectors (FIGURE 1-1) for attaching the sensors. Besides the connectors, a wiring panel is included allowing the measurement of additional sensors. The RAWS-F typically communicates via our GOES satellite transmitter. It is also compatible with other communication equipment such as telephones, digital cellular transceivers, and radios. This station is ideal for prescribed burns or other temporary installations. The RAWS-F Quick Deployment Weather Station is shown in FIGURE 1-2.
Specifications are available from our web site at www.campbellsci.com.

3. Station Siting and Orientation
3.1 General Description
Selecting an appropriate site for the RAWS 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.
NOTE
WARNING
See Section 7, References, for siting references.
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.
3.2 Air Temperature and Relative Humidity
A temperature and relative humidity (RH) sensor should be located over an open level area at least 9 m in diameter (EPA). The surface should be covered by short grass, or where grass does not grow, the natural earth surface. The sensor must be housed inside a radiation shield and adequately ventilated.
Situations to avoid include:
large industrial heat sources
rooftops
steep slopes
sheltered hollow
high vegetation
shaded areas
swamps
areas where snow drifts occur
low places holding standing water after rains
6
3.3 Precipitation
A rain gage should be located over an open level area covered by short grass, or where grass does not grow, the natural earth surface. Level the RAWS station to ensure the sensors are level. Level the rain gage by adjusting the rain gage leveling screw. A post level and compass ship with the RAWS (pn
16770).
RAWS-F Remote Automated Weather Station for Fire Weather
NOTE
Take off the funnel and remove the rubber band securing the tipping bucket mechanism during transport.
3.4 Solar Radiation
A solar radiation sensor should be located to avoid shadows on the sensor at any time. Orient the RAWS facing the equator, minimizing the chance of shading from other weather station structures. Reflective surfaces and sources of artificial radiation should be avoided. Level the RAWS to ensure the solar radiation sensor is level.
3.5 Wind Speed and Direction
A wind sensor 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.
3.6 Barometric Pressure (optional)
The barometric pressure sensor is mounted to the back plate inside the RAWS environmental enclosure.
3.7 Fuel Moisture and Fuel Temperature (optional)
The fuel moisture and fuel temperature sensor should be left outside at the field site continually exposed to the same conditions as the forest fuels. The fuel moisture and fuel temperature dowel rods absorb and desorb moisture from its surroundings. Install the probes horizontally on the mounting stake and face the sensors towards the equator above a representative forest floor duff layer. Place the sensor away from foot traffic areas.
4. Sensor Maintenance, Calibration, and Troubleshooting
4.1 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 (for example, bearing torque), and sensor component replacement, generally requires sending the instrument to Campbell Scientific.
7
RAWS-F Remote Automated Weather Station for Fire Weather
A station log should be maintained for each weather station that includes equipment model, serial numbers, and maintenance that was performed.
NOTE
Contact Campbell Scientific, phone (435) 227-9000, for an RMA number before returning sensor or equipment for service.
4.2 Air Temperature and Relative Humidity
4.2.1 General Description
Rotronic’s HydroClip2 Air Temperature and Relative Humidity Sensor (pn HC2S3-QD) shown in FIGURE 4-1 contains a Platinum Resistance Thermometer (PRT) and a Rotronic’s IN1 capacitive sensor. The probe has a voltage output for each sensor.

The temp/RH sensor requires minimal maintenance. Check monthly to make sure the radiation shield is free from debris. The filter at the end of the sensor should also be checked for contaminates. When installed in close proximity to the ocean or other bodies of salt water, a coating of salt may build up on the radiation shield, sensor, filter and even the RH chip. A buildup of salt on the filter or RH chip will delay or destroy the response to atmospheric humidity. The filter can be rinsed gently in distilled water. If necessary, the chip can be removed and rinsed as well. Do not scratch the RH chip while cleaning.
Recalibrate the temp/RH sensor annually. Obtain an RMA number before returning this sensor to Campbell Scientific for recalibration.
4.2.5 Troubleshooting
4.3 Rain Gage
4.3.1 General Description
If a problem is suspected, check the sensor cable. Disconnect the connector and look for damaged pins. Verify that the sensor body is connected to the sensor head. Under the filter assembly, verify the sensors are connected but not touching. Try connecting a substitute sensor. Obtain an RMA number before returning this sensor to Campbell Scientific for repair.
The Texas Electronics Rain Gage (pn TE525-QD) shown in FIGURE 4-2 is an adaptation of a Weather Bureau tipping bucket rain gage. The rain gage has a 6 inch collector.

The CS506 Fuel Moisture element and 26601 dowel should be changed at least once a year with a new element in the spring. Since the characteristics of wood change so rapidly, more frequent dowel replacements may be desirable. To change the sensor element, loosen the Phillips head screws and replace with a new element. Tighten the screws after replacing the element.
The CS205 Fuel Moisture Stick should be changed annually or more frequently as required. The wood should visually appear fresh and new, not gray or discolored. The CS205 inserts into the compression fitting so that compression is applied to the split end of the stick gripping the 107 temperature probe.

4.7.4 Calibration
For most applications, it is unnecessary to calibrate the CS516-QD Fuel Moisture and Fuel Temperature Sensor. However, for those users that are interested in calibrating this sensor, please contact a Campbell Scientific Applications Engineer.
4.7.5 Troubleshooting
If a problem is suspected, check the sensor cable. Disconnect the connector and look for damaged pins. Verify the CS506 sensor element is securely fastened. Try connecting a substitute sensor. Obtain an RMA number before returning the CS516-QD sensor to Campbell Scientific for repair.
5. Equipment Maintenance, Calibration, and Troubleshooting
5.1 Solar Panels
5.1.1 General Description
NOTE
5.1.2 Wiring
The solar panel is a photovoltaic power source used for charging lead acid batteries. The SP20-QD 20 watt solar panel is used for system configurations that have higher-than-average power requirements. It is also recommended for use at higher elevations and latitudes. The solar panel should be mounted facing the equator.
The SP10-QD 10 watt solar panel is recommended for a RAWS where NO communication equipment is used. The SP20-QD 20 watt solar panel is recommended for a RAWS where communication equipment is used (for example, GOES, voice, cell phone, or radio).
The solar panel selected for the RAWS depends on the station power requirements, specifically the communication equipment selected for the station.
The SP10-QD solar panel outputs 0.59 Amps, 8.9 Watts typical peak power.
The SP20-QD solar panel outputs 1.17 Amps, 18 Watts typical peak power.
The solar panel attaches to the connector panel labeled “BATT CHARGER/SOLAR PANEL”. Inside the RAWS environmental enclosure, the “BATT CHARGER/SOLAR PANEL” connector pin A and pin B are wired to the CH100’s “CHG” and “CHG” ports. Polarity does not matter; either lead can be connected to either terminal. The CH100 has two functions: blocking any current flow from the battery to the solar panel, and limiting the source current to the battery.
19
RAWS-F Remote Automated Weather Station for Fire Weather
5.1.3 Maintenance
An occasional cleaning of the glass improves the solar panel’s efficiency.
5.1.4 Calibration
No calibration is required.
5.1.5 Troubleshooting
If a problem is suspected, the solar panel may be checked by measuring the voltage output from the solar panel. Check the voltage with a voltmeter connected between the two leads going to the CH100’s “CHG” “CHG” terminals located inside the environmental enclosure (15 to 28 Vdc). There must be solar radiation incident on the panel and there must be a load connected to the solar panel. The load can be the datalogger, other equipment, or a 75 ohm resistor capable of dissipating solar panel power between the two leads. No voltage output implies a bad solar panel, regulator, or cable. The magnitude of the voltage output depends on the incident solar radiation. Check the sensor cable. Disconnect the connector and look for damaged pins. Try connecting a substitute panel. Obtain an RMA number before returning the SP10/20-QD to Campbell Scientific for repair.
5.2 Charger/Regulator
5.2.1 General Description
The 12 Volt charger/regulator (pn CH100) is a charging regulator for 12 V rechargeable batteries. The CH100 is connected to an external charging source such as an unregulated solar panel (pn SP20-QD or SP10-QD) or a wall charger (pn 9591). The CH100 has two functions: blocking any current flow from the battery to the solar panel, and limiting the source current to the battery.
FIGURE 5-1. 12-volt charger/regulator

5.2.2 Wiring
RAWS-F Remote Automated Weather Station for Fire Weather
The leads from the RAWS connector panel “BATT CHARGER/SOLAR PANEL” connector COLOR CODED PURPLE are wired to the CH100 “CHG” terminals. Polarity does not matter; either lead can be connected to either terminal. The charge indicating diode should be “ON” when voltage to the charging circuitry (CHG Terminals) is present.
An internal and/or external battery can be connected to the CH100 by means of the INT (Internal) or EXT (External) connectors. The battery red lead connects to the positive battery terminal and the black lead connects to the negative terminal.
NOTE
WARNING
CAUTION
CAUTION
5.2.3 Maintenance
An “external battery cable” (pn 6186) ships with the RAWS-F.
Connect 12 V power to the datalogger and/or peripherals using the “+12 and Ground” terminals. The ON-OFF switch applies power to these 12 V terminals.
Reversal of battery polarity will damage the CH100 or battery.
A battery must be attached for the CH100 to function correctly as a power supply.
It is possible to leave two batteries connected. The battery connections are diode isolated; however, if one of the batteries fails, it could draw all the charging current and the other battery will be discharged.
There are no user-serviceable parts on the CH100. No maintenance is required.
5.2.4 Calibration
5.2.5 Troubleshooting
No calibration is required.
If a problem is suspected, the CH100 may be checked by measuring:
input voltage (CHG terminals) from the solar panel (15 to 28 Vdc) or
input voltage from the wall charger (pn 9591) about 18 Vac RMS
charging output voltage (BATT INT or EXT terminal) with battery
disconnected about 13.5 to 14 Vdc
power out (+12 terminals) about 11 to 14 Vdc
21
RAWS-F Remote Automated Weather Station for Fire Weather
No voltage output implies a bad solar panel, regulator, or battery. If problems persist, obtain an RMA number and return the device to Campbell Scientific for repair.
NOTE
Power out (+12 terminals) is controlled by the CH100 ON-OFF switch position.
5.3 Battery
5.3.1 General Description
Two power supply options are offered for the RAWS-F. The ─24 option includes a 24 A h sealed rechargeable battery, an external 20 W solar panel, and a CH100 regulator. The 7 option includes a 7 Ahr sealed rechargeable battery, an external 10 W solar panel, and a CH100 regulator.
WARNING
5.3.2 Wiring
RAWS rechargeable batteries are designed to be float charged. Permanent damage occurs and battery life is shortened if the battery is allowed to discharge below
10.5 volts.
The RAWS rechargeable battery should be connected to the CH100’s INT (Internal) connector. The battery red lead connects to the positive battery terminal and the black lead connects to the negative terminal. If desired, an external battery can be connected to the CH100’s EXT (External) connector. An “external battery cable” (pn 6186) ships with the RAWS-F.

5.4 GOES Transmitter (Optional)
5.4.1 General Description
The High Data Rate GOES Transmitter (pn TX320) shown in FIGURE 5-2 supports one-way communication, via satellite, from a Campbell Scientific datalogger to a ground receiving station. Satellite telemetry offers a convenient communication alternative for field stations where phone systems or RF systems are impractical or rendered unreliable after a tragedy to the local infrastructure. Data transmission rates of 100, 300, and 1200 bps are supported. Because clock accuracy is critical for GOES satellite telemetry, the TX320 includes a robust, TCXO-based real-time clock and a GPS receiver.
The TX320 has two siting requirements for proper operation. The GOES antenna must have a clear view of the spacecraft. The GOES antenna is directional and should be aimed at the spacecraft; both elevation and azimuth are unique to the location of the planet and must be set. A poorly aimed antenna will cause a drop in signal strength or possibly prevent successful transmission.
NOTE
For more information on the TX320 and antenna siting, go to our website at
www.campbellsci.com, enter the “TX320” in the “Search” box, and go the
equipment manual. The TX320 manual is also provided on the ResourceDVD which ships with the RAWS-F.
The spacecraft specific DCP-Setup parameters for the GOES transmitter must be entered in the CR1000KD menus for the TX320 to work properly.

8. RAWS Orientation
8.1 Determining True North and Sensor Orientation
Orientation of the wind direction sensor is done after the datalogger has been programmed and the location of True North has been determined. True North is usually found by reading a magnetic compass and applying the site-specific correction for magnetic declination; where the magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USGS map, local airport, or through the web calculator offered by the USGS (Section 8.2, USGS Web Calculator). A general map showing magnetic declination for the contiguous United States is shown in FIGURE 8-1.
Declination angles are always subtracted from the compass reading to find True North. A declination angle east of True North is reported as positive a value and is subtracted from 360 (0) degrees to find True North as shown FIGURE 8-2. A declination angle west of True North is reported as a negative value and is also subtracted from 0 (360) degrees to find True North as shown in FIGURE 8-3. Note that when a negative number is subtracted from a positive number, the resulting arithmetic operation is addition.
For example, the declination for Longmont, CO is 10.1°, thus True North is 360° 10.1°, or 349.9° as read on a compass. Likewise, the declination for Mc Henry, IL is ─2.6°, and True North is 0° (2.6°), or 2.6° as read on a compass.

FIGURE 8-3. A declination angle west of True North (negative) is

8.2 USGS Web Calculator
The USGS provides an easy way of determining the declination of a specific site. Since magnetic declination fluctuates with time, it should be adjusted each time the wind sensor orientation is adjusted. The calculator can be accessed at: www.ngdc.noaa.gov/geomagmodels/Declination.jsp. FIGURE 8-4 shows an example for Logan, UT.
RAWS-F Remote Automated Weather Station for Fire Weather
FIGURE 8-4. USGS web calculator
In the example above the declination for Logan, UT is 12º 24 or 12.4º. As shown in FIGURE 8-4, the declination for Utah is east (positive), so True North for this site is 360 12.4 = 347.6 degrees. The annual change is 7 minutes west per year or 7 minutes/year.
