XPLM_API int XPLMGetWeatherAtLocation(
double latitude,
double longitude,
double altitude_m,
XPLMWeatherInfo_t * out_info);
Get the current weather conditions at a given location. Note that this does not work world-wide, only within the surrounding region. Return 1 if detailed weather (i.e. an airport-specific METAR) was found, 0 if not. In both cases, the structure will contain the best data available. This call is not intended to be used per-frame.
