The 208 statement is intended to read the output of the site weather station and put the results
into the ATIS output file. This statement as opposed to the 202 statement is not sensor specific.
All measurements are in the English system of measure. The 208 statement may be put within an
individual group to log the weather conditions during the groups execution, or within its own
special weather group. A special weather group is shown below:

103
1000 15 2 2400000 2600000 0.0 24.0 15 5 3600 3 WEATHER ENG
208
115

The important features of the above statement are the number of observations being set for 15 and
the probability set to 3600. This will result in the weather being read 15 times during the night
with approximately 1 hour (3600 seconds) intervals. Note also that the priority has been set to a
relatively high value to force execution of this group. Since this function takes no real telescope
time it does not interfere with normal operation or the priorities set for the observation groups.
The group type should be set to 15. Group type 15 has been defined in ATIS2000 as a special weather
group. The weather group should be the first group following the 101 and 102 commands in an ATIS
input file.

Where:

1. JD.FJD is the date and time the weather station was read.
2. Wind Direction is in degrees East of North.
3. Wind Speed is in Miles per Hour.
4. Outside Temperature is in Degrees Fahrenheit.
5. Dew Point is calculated and in Degrees Fahrenheit.
