Figure 12 Ceilometer CT25KAM
User's Guide ______________________________________________________________________
24 __________________________________________________________________ M210455EN-B
CT25KAM employs pulsed diode laser LIDAR (Light Detection and
Ranging) technology for cloud detection, precipitation, and other
obstructions to vision, and accurate cloud heights and vertical
visibility determination.
The standard measurement range of CT25KAM extends up to 25 000
feet (7.5 km) covering most heights where dense clouds appear. The
instrument is capable of reporting up to three cloud layers
simultaneously. It detects the cloud base reliably in fog, rain, snow,
and haze. If the cloud base is obscured, CT25KAM measures and
reports vertical visibility.
Extensive internal monitoring is supported by a comprehensive set of
user commands that can be given locally or remotely. Internal
monitoring includes a sensor measuring the outgoing laser pulse
energy, circuitry checking the receiver sensitivity, a sensor monitoring
window contamination, and two sensors measuring the tilt angle.
These and other internal measurements are used by the diagnostics
software and the detection algorithm for maximum reliability and ease
of use.
A special additional tilt sensor is provided as standard for
automatically compensating uneven terrain. Installation is made easy
and fast when no exact leveling is required. The cloud coverage
algorithm in the CT25KAM is a further development of the algorithm
specified by FAA. Cloud coverage (amount) is reported in 0 to 8
octas, according to WMO regulations.
Present Weather Detector PWD11A

VAISALA _______________________________________________________________________ 25
weather sensor. In addition, PWD11A can measure the intensity and
amount of both liquid and solid precipitation.
The versatility of PWD11A is achieved with a unique operating
principle. PWD11A measures an estimate of the precipitation water
content with a capacitive device and combines this information with
optical scatter and temperature measurements. These three
independent measurements together sufficiently provide data for an
accurate evaluation of the prevailing visibility and weather type.
PWD11A is calibrated with reference to a highly accurate
transmissometer. An extensive self-diagnostic procedure continuously
monitors the sensor status. Dirt and foreign particles on the lens are
detected automatically, minimizing the risk of false high values. A
special calibration kit is provided as an option for conducting field
calibration under practically all weather conditions.
PWD11A is small and lightweight, thus being easy to install on the
sensor cross arm. In addition to the standard sensor operation, the
MAWS software adds extra features such as reporting of coded
weather type identifications as plain text in the output reports.

MIDAS IV Software
This section contains detailed information on operating TACMET
MAWS with the MIDAS IV software.
The MIDAS IV software collects measured and calculated data from
the TACMET MAWS systems. In addition, it automatically generates
METAR reports, archives data for 30 days on the hard disk or any
other selected storage media, and distributes data further to other
systems. MIDAS IV allows the user to edit the METAR reports with
easy-to-use templates. Moreover, MIDAS IV provides the Event
Monitor option, with which the operator can monitor the system and
sensor alarms.
MIDAS IV data can be accessed through four workstation
applications. These applications are:
- Weather View for data display
- US METAR Template for sending a METAR/SPECI message
- Event Monitor for viewing and acknowledging events
- ASCII Log View for viewing stored history data.

METAR/SPECI Template
The METAR/SPECI template (referred to as US METAR template)
generates a METAR observation report at the intervals specified in the
system configuration. Sensor data is automatically updated onto the
template. The observation follows the format specified by WMO. The
observations can be edited or augmented by the operator and are not
distributed until approved by the operator. Special observations are
generated when weather parameters reach the threshold specified in
the system configuration and as required by ICAO Annex III. There is
also support for corrected and retarded messages.
The template window appears on your screen (see Figure 37 below)
when it is time to send a METAR/SPECI report. This window is also
displayed when you open the application yourself. The template is
similar for both METAR and SPECI reports; the only difference is the
Type field.

METAR/SPECI service starts automatically at system startup. When
you do not need to use the application, you can minimize the window.

The steps of producing a METAR/SPECI report are:
- Checking and editing data fields
- Adding remarks
- Building the report
- Sending the report.
Checking and Editing Data Fields
When the US METAR template window appears on your screen,
several fields are already filled with sensor data. These fields are
called automatic data fields, because the system automatically fills
them in for you.
The template also includes manual data fields. They are called manual
because they are not filled in automatically. You need to fill them in
yourself by clicking the field and entering the value. When the

NOTE
Slashes in manual fields are normal. When you see slashes in manual
fields, enter data in the field.
Adding Remarks
You can add remarks to the METAR report whenever necessary. A
remark is any comment you consider important; it could be related, for
instance, to runway conditions.
Building the Report
Build the report by clicking the BUILD button. The system validates
the report. If the system displays error messages, do one of the
following:
- If you click Yes, the report is built. Some data may be marked with
slashes.
- If you click No, the system does not continue building the report.
You can correct the values in the data fields and click the BUILD
button again.
When you click the BUILD button, the system performs a set of
validations, depending on the configuration. The system checks that
certain values, for example, temperature, dew point, and pressure fall
within the normal range.
The system also checks that present weather codes and numeric data
are consistent and that you have entered cloud amount data together
with the cloud height data.
If the values are valid, the system builds the report and you can send
it. If the system finds invalid values, it informs you about them with
error messages.
CAUTION
If the No consistency check option in the Settings menu is selected,
the system will not display the error messages. Instead, it replaces the
incorrect values by slashes in the final report code.
The system displays the final report text in the CODE field. Check the
report code. If there are errors in the code, correct the values in the
template data fields and click BUILD again.

Event Monitor
Event Monitor is an application for viewing and acknowledging
events, warnings, and alarms in the system.
Events are divided into three categories: operational, technical, and
internal events. Operational events are notifications about changed
meteorological conditions. Technical events are related to the
functioning of the sensors and to the communication between the
sensors and MIDAS IV Computer. Internal Events concern the
internal operation of the system, normally the operation of the system
services.
The system creates an event when technical or meteorological
conditions change.
Double-click the Event Monitor icon on the desktop to open the Event
Monitor.

Diagnostics Monitor
The Diagnostic Monitor (ROA Diagnostics) application is a tool for
monitoring the status of the MIDAS IV system. In Diagnostic
Monitor, you can view the status of a CDU (Central Data Unit), ROA
(Remote Object Architecture) objects and ROA users. You can also
check the location of a sensor.
When you get an Internal Event message in Event Monitor, there may
be a problem with the CDU. In such a situation, you need to use
Diagnostic Monitor to view the system status more closely. When
there is a Technical Event message in Event Monitor, you need to use
Diagnostic Monitor to look up the location of the sensor causing the
event.
CAUTION
Diagnostic Monitor is also an installation tool used by Vaisala
personnel. For this reason, it contains some functions you must not
use. Incorrect use of these functions can result in serious system
problems.
This manual includes instructions only for those functions that you
can safely use in your troubleshooting tasks. Do not use functions
that are not covered in this manual.
When starting troubleshooting with Diagnostic Monitor, you need to
connect to the system in question.
1. Select System - Connect.
2. The Connect window appears.
3. Select the CDU (for example MIDAS IV TACMET) and click
OK.
4. The Statuses tab appears.

ROA Object
A ROA object is a runtime data container used by the remote object
architecture. The data set it contains can be one of the following:
- Measured weather parameter values produced by a sensor
- Calculated values produced by meteorological services
- Alarm messages produced by the Alarm Service
- Weather report data.
The status of ROA objects in your system is indicated in the Statuses
tab by the color of the Objects icon. In a normal situation, the
Objects icon is green. If it is red or yellow, you need to open the
Objects window by selecting View - Objects. In the Objects
window, you can see the name, status, and value of the problem object
and open a data item window for it.
Figure 43 below shows the Objects window. The window is similar
for all system types. You can display the Objects window by selecting
Objects from the View menu.
Figure 43 Objects Window in Diagnostic Monitor
Chapter 3 ________________________________________________________________ Operation
VAISALA _______________________________________________________________________ 87
The columns in Figure 43 on page 86 are explained below:
Name = The Name column shows the ROA object name. By
double-clicking the name (of objects having Access type
Application), you can open a data item window for this
object and view data items belonging to it.
Existence = In the Existence column, the system shows the status of
the ROA object in question. In single-CDU systems, the
normal status is Obligatory.
In error situations, the status can be either Missing or
Unknown. A Missing status is also shown by the red
object status icon.
When the existence of a ROA object is Missing, the
system sends an Internal message Object information
conflict to Event Monitor. A Missing object status
means that the object is not running properly in the
system or, in rare situations, that the object is missing
from the system altogether.
If the existence of a ROA object is Unknown (yellow), it
usually means that there is an application running for
which you do not have a proper license. See also Table
32 below.
Access = Objects are divided into two groups by their access type:
Application and System. If an object has the access type
Application, you can open a data item window for that
object by double-clicking its name. Objects with the
access type System are internal system objects, and you
cannot open a data item window for them; they are only
intended for system internal use.
Types = The Types column contains programming information
intended for Vaisala internal use.

ROA User
A ROA user is a program running in the MIDAS IV system. The term
"user" should be understood from the system’s point of view: ROA
users are applications and programs that are using the CDU’s services.
NOTE
In this context, the word user does not refer to the end user of
MIDAS IV workstation.
A ROA user is one of the following:
- Workstation application (for example Weather View,
METAR/SPECI)
- System program.
The status of ROA users in your system is indicated in the Statuses
tab by the color of the Users icon. In a normal situation, the Users
icon is green. If it is red or yellow, you need to open the Users
window by selecting View - Users. In the Users window, you can see
the name, address, port, and status of the problem ROA user.

Address = The Address column shows the IP address of the
computer running the software in question.
Port = The Port column shows the TCP/IP port of the computer
running the software in question.
Host = The Host column contains information intended for
Vaisala internal use.
Network = The Network column shows the version number of the
ROA network library used in the application. The
version number consists of three groups separated by a
dot (for example 1.43.03). The first two groups should
be the same for each ROA user. If they are not, an old
version of the ROA user in question is running in the
system.
Existence = The Existence column shows the status of the ROA user.
A ROA user can be Obligatory, Violation/Unknown,
or Missing.
The normal status is Obligatory. If the system cannot
find a ROA user, the status turns Missing. This means
that a system program has stopped running, or that an
end user has inadvertently closed an application that
needs to be constantly open in a workstation
(METAR/SPECI).
If the ROA user status is Violation/Unknown, it means
that there is a non-licensed or non-configured ROA user
running in the system.
You might also see the statuses Floating and Inactive in
the Existence column. These statuses are mainly
intended for Vaisala internal use.
