Response

A JSON object with the requested information is returned. The result is grouped in a couple of sections:

metar Last METAR data, raw and decoded
airport Information about the airport, including timezone and latitude/longitude
station Airport information of the weather station (if different from airport)
stations List of alternatives for this weather station: nearby airports with METAR and/or TAF
runways Runways of the requested airport with the crosswind data.
Crosswind data is calculated using the airport\'s own METAR or the nearest available station.
