Smartphone evapotranspiration field campaign data Rollesbroich

This dataset contains observations made by smartphone and an additional handheld sensor in order to estimate evapotranspiration. These include luminence, surface temperature, air temperature, air pressure, relative humidity, and wind speed. The dataset also contains hourly routine meteorological observations, as well as evapotranspiration observations by a set of 6 weighing lysimeters and eddy covariance, all collected at the Rollesbroich TERENO site, which is operated by the Institute of Bio- and Geosciences of FZ Julich. The smartphone observations were used to train a simple machine learning algorithm on the observed fluxes.
