    4343When there are gaps in the Fluxnet time-series, 3-hourly non-bias ERA-interim data are used and consequently interpolate to match the half-hourly time resolution of the Fluxnet data. 'Air Temperature', 'Water Vapour Pressure', 'Wind speed', 'Longwave down Radiation' and 'Pressure' are linearly interpolated. 3-hourly precipitation are spread at half-hourly resolution using the observed mean frequency of precipitation. For the shortwave down radiation interpolation, we account for the solar angle evolution over the 3-hourly time period.
