Abstract
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 large weighing lysimeter and eddy covariance, all collected at the Büel meteorological station in the Rietholzbach catchment, which is operated by the Land-Climate Dynamics group at the Institute for Atmospheric and Climate Science (IAC), ETH Zurich. The smartphone observations were used to train a simple machine learning algorithm on the observed fluxes.

Jasper Lammers 26-10-2023, Wageningen This readme concerns the Rietholzbach_data.csv file. The Excel file contains meteorological data from Büel field site and handheld meteorological observations at the same site. From the data a relationship is established to determine the evapotranspiration through a machine learning method trained on data of the handheld deivces (Weatherflow WEATHERmeter and a CAT S62 Pro). The Büel data are owned by the Land-Climate Dynamics group at the Institute for Atmospheric and Climate Science (IAC), ETH Zurich. The names and description in the Excel file of handheld devices' data are the following: T_air_x: Air temperature (degrees Celsius) Pressure_x: Air pressure (mbar) RH_x: Relative humidity (%) wind: Wind velocity (m/s) T_soil: Soil temperature (degrees Celsius) IR: Illuminance recording from Sensors app (lux/m2) Cos(pitch): Cosine of the pitch recording from the Sensors app (-) The names and description in the Excel file of reference Büel data are the following: T_air_y: Air temperature (degrees Celsius) ET: Evapotranspiration from lysimeter (mm) LE: Latent heat flux from eddy covariance (W/m2) H: Sensible heat flux from eddy covariance (W/m2) Pressure_y: Air pressure (mbar) RH_y: Relative humidity (%) v_wind: Average wind velocity (m/s) ISR: Global radiation (W/m2) Qnet: Net radiation (W/m2) LE_ET: Evapotranspiration from eddy covariance converted to water equivalent (mm) Time is the sampling moment (yyyy-mm-dd HH:MM:ss)
