Wind on the strip—The strip’s direction is not mapped
Computed from the forecast air temperature, dew point and station pressure (NWS formulas; the correction factor by SAE J1349 and the older 60 °F STD standard). Track temperature is estimated from sun, wind and the surface; it is not a sensor reading. How these are figured.
