5.8.5 Feeding In SWS Data
1. For testing, manually feed in example data to the /usr/iris_data/metar_in
directory.
2. For testing, download current METARs from: http://aviationweather.gov/adds/metars/ .
You must edit the file to add the GTS header, and METAR on each line.
3. Check that you get an SWS product in IRIS.
4. Check for warnings in the pipe log file
metar2iris.log
in
/usr/iris_data/log
.
The time stamps consist of the day of the month, followed by hour and minute. The
pipe must guess the month and year, based on the current time.
IRIS expects to receive one ASCII file containing all SYNOP or METAR messages from
the past 1 hour time. METAR special reports can also be sent into IRIS in-between hours.
5.8.6 METAR and WMO File Format Examples
