WeatherXds: STATION_POSITION

[kettenis]

If this data variable isn't present, is the position expected to match the associated antenna specified by the antenna_name coordinate? And how does association between station_name and antenna_name work? My guess would be that the association would be done via the position in the last and that this allows for stations not associated with a particular antenna by specifying a shorter list of antennas? Would be good to make this a bit more specific in the documentation.

Yes, if weather_xds.STATION_POSITION is not present then the weather_xds.ANTENNA_NAME should be used to get the antenna_xds.ANTENNA_POSITION. This only allows a weather station to be associated with a single antenna. We will clarify this in the documentation. Maybe we should make the weather_xds.STATION_POSITION non-optional.

"This only allows a weather station to be associated with a single antenna." could be a problem. One solution is to remove ANTENNA_NAME from weather_xds and add WEATAHER_STATION_NAME to antenna_xds. This would allow multiple antennas to be associated with the same weather station.
