Colors denote the evaporative fraction averaged over the timespan of the respective data product after filtering for warm days (ERA5 temperature > 278 K) and availability of all gridded data products: a GLEAM, 2003–2017, b FLUXCOM, 2001–2015, and c ERA5, 1981–2017 (see “Data” in “Methods”). d Evaporative fraction inferred from balloon soundings using CLASS4GL in colored circles, averaged over all stations from the morning to the afternoon sounding for within a 5.0° × 5.0° grid cell and all available sounding days. The sizes of the circles correspond to the amount of available sounding days.
