Wind speed at the airports

Could you help me?

Service does not give data on wind speed at the airports.

Service writes that all flights that we would not be filled, the wind speed is equal to 0. I can not understand - this is a mistake, or so you draw information on wind speed for the flight on which the airline does not give you the information.

Our METAR parsing only supports knots encoded wind measurements, not meters/sec (“MPS”). However, you are free to parse and extract the speed out of the “raw_data” element in the returned structure.
