ERA5 Ag

Description: Daily surface meteorological data for the period from 1979 to present as input for agriculture and agro-ecological studies. This dataset is based on the hourly ECMWF ERA5 data at surface level and is referred to as AgERA5. Acquisition and pre-processing of the original ERA5 data is a complex and specialized job. By providing the AgERA5 dataset, users are freed from this work and can directly start with meaningful input for their analyses and modelling. To this end, the variables provided in this dataset match the input needs of most agriculture and agro-ecological models. Data were aggregated to daily time steps at the local time zone and corrected towards a finer topography at a 0.1° spatial resolution. The correction to the 0.1° grid was realized by applying grid and variable-specific regression equations to the ERA5 dataset interpolated at 0.1° grid. The equations were trained on ECMWF's operational high-resolution atmospheric model (HRES) at a 0.1° resolution. This way the data is tuned to the finer topography, finer land use pattern and finer land-sea delineation of the ECMWF HRES model. 

Organization: ECMWF

Spatial resolution: 9600 m (1/10-deg)

Time Span: 1979-01-01 to Present (updated daily with 7 day lag time)

Variables:

  • Minimum/Maximum/Mean Temperature (mean_2m_air_temperature, maximum_2m_air_temperature, minimum_2m_air_temperature)
  • Dewpoint Temperature (dewpoint_2m_temperature)
  • Precipitation (total_precipitation)
  • Snow (Snow_Depth, SWE)
  • Wind speed (wind_speed)
  • Vapour pressure (vap)
  • Downward Solar Radiation (srad) (W/m^2)
    • Reflects average over all hours of the day.
    • To go from Watts/m^2 to MJ/(m^2day) you need to multiply the number of sec in a day: watts/meter² x 86400 s/day x 1 MJ/10^6 J = MJ/(meter²*day).
