The data provided data are historical weather measurement and forecast at three location in France. Measurements are inside files named OBS_xxx Forecasts are inside files names YYY_xxx, with YYY is the name of the forecast simultion (GFS0.25, WRF12km or WRF3KM). In the two cases, xxx is the name of the site (Site 1, Site2 or Site3). Description of OBS_xxx files: - One line per measurement with hourly resolution - columns are: Date(TU),Temperature2m_degC,WindSpeed10m_m/s,WindDirection10m_m/s Date = date of measurement in TU and format DD/MM/YYYY HH:MM Temperature2m_degC = air temperature at 2m height in °Celsius WindSpeed10m_m/s = wind speed at 10m height in m/s WindDirection10m_deg = wind direction at 10m height in deg. (0 or 360 = wind from north to south, 45°=wind from east to east, ....) If measurement is not available for a specific hour for one parameter, the value "-999" is used. The observation data go: from 16/04/2021 00H to 31/01/2022 23H Description of YYY_xxx files: - One line per forecast with hourly resolution - columns are: First date run (TU),forecast hour,Temperature2m_degC,WindSpeed10m_m/s,WindDirection10m_m/s First date run (TU) = date of start of the forecast in TU and format DD/MM/YYYY HH:MM. HH could be 00 and 12 according to the cycle of forecast start. forecast hour = forecast hour from the start of the forecast date. 00 = forecast for "first date run". 01 = forecast for "First date run" + 1 hour. .... 95 = forecast for "First date run" + 95 hours. For GFS0.25, forecast hour go from 00 to 95 For WRF12km, forecast hour go from 00 to 95 For WRF3m, forecast hour go from 00 to 95 Temperature2m_degC = air temperature at 2m height in °Celsius WindSpeed10m_m/s = wind speed at 10m height in m/s WindDirection10m_deg = wind direction at 10m height in deg. (0 or 360 = wind from north to south, 45°=wind from east to east, ....) If measurement is not available for a specific hour for one parameter, the value "-999" is used. The forecast data go: from 13/04/2021 00H + 72H = first forecast for the 16/04/2021 00H to 31/01/2022 12H + 11H = last forecast for the 31/01/2022 23H
