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.
