AgERA5

Agrometeorological indicators from 1979 to present derived from reanalysis

https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-agrometeorological-indicators?tab=overview

This dataset contains daily surface meteorological data from 1979 to present for agricultural and ecological use cases. AgERA5 is based on the hourly ECMWF ERA5 data from ground level. Users can input this ready-processed data directly into their analyses and modelling. The dataset was tailored to match the input needs of most agricultural and ecological models.

Data were aggregated to daily time steps at the local time zone and corrected to a finer topography at a 0.1° spatial resolution. The correction was applied to the ERA5 dataset interpolated at 0.1° grid with variable-specific regression equations, which were trained on ECMWF's operational high-resolution atmospheric model (HRES). Using this method, the data is tuned to the finer topography, finer land use pattern, and finer land-sea delineation of the ECMWF HRES model.

This dataset is created as part of the Copernicus Climate Change Service (C3S).

Variable Name	Unit	Description
10m wind speed	$m\ s^{-1}$	Mean wind speed at a height of 10 meters above the surface over the period 00h-24h local time.
2m dewpoint temperature	$K$	Mean dewpoint temperature at a height of 2 meters above the surface over the period 00h-24h local time. The dew point is the temperature to which air must be cooled to become saturated with water vapor. In combination with the air temperature it is used to assess relative humidity.
2m temperature	$K$	Air temperature at a height of 2 meters above the surface.
Cloud cover	Dimensionless	The number of hours with clouds over the period 00h-24h local time divided by 24 hours.
Precipitation flux	$mm\ day^{-1}$	Total volume of liquid water (mm3) precipitated over the period 00h-24h local time per unit of area (mm2), per day.
Snow thickness	$cm$	Mean snow depth over the period 00h-24h local time measured as volume of snow (cm3) per unit area (cm2).
Solar radiation flux	$J\ m^{-2}\ day^{-1}$	Total amount of energy provided by solar radiation at the surface over the period 00-24h local time per unit area and time.
