Weather Data

The best available weather data is combined by data.wx.get and may provide the following variables:

Variable Description
F1 Calculated system flags (contamination)
F2 Variable source flags
P Ambient pressure (hPa)
T Ambient temperature (C)
U Ambient relative humidity (percent)
TD Dew point temperature (C)
WD Wind direction (degrees true)
WS Wind speed (m/s)
WX Current weather code
WZ Visibility (km)
WD1 Wind direction at alternate height 1 (degrees true)
WS1 Wind speed at alternate height 1 (m/s)
WD2 Wind direction at alternate height 2 (degrees true)
WS2 Wind speed at alternate height 2 (m/s)
T1 Ambient temperature at alternate height 1 (C)
T2 Ambient temperature at alternate height 2 (C)
T3 Ambient temperature at alternate height 3 (C)
WI Precipitation intensity (mm/h)

Note that the record type does not follow the convention, it is always just “wx” with no type suffix.
