The METAR data files are saved by nbsp in a form that are readily usable by MetarWeather. However, the noaaport data directory (/var/noaaport/data) must be exported via samba, as explained in the configuration section of the manual.
Then from the MetarWeather program, the data is obtained by opening the files that are in the subdirectory
metar/metarweatherIf a collective file is opened (for example Louisiana/Louisiana.txt), then the last report from all the stations of the Lousiana collective are displayed. If a particular station file is opened, then the last reports from that station are displayed.
