The AgERA5 dataset provides 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, with data from January 1, 1982, through December 31, 2022, extracted for a grid located in Angochen, Nampula province of Mozambique.

Usage

Format

A data frame containing daily observations of weather variables:

  • GridID: Grid ID of the location.

  • Lat: Latitude of the grid in decimal degrees.

  • Lon: Longitude of the grid in decimal degrees.

  • Elev: Elevation above sea level in meters.

  • WHC: Water holding capacity in millimeters (mm).

  • Year: Year of record ("YYYY").

  • Month: Month of record ("MM").

  • Day: Day of record ("DD").

  • Rain: Daily precipitation in millimeters (mm/day).

  • Tmax: Daily maximum temperature at 2 meters height in degrees Celsius (°C).

  • Tmin: Daily minimum temperature at 2 meters height in degrees Celsius (°C).

  • Rs: Total amount of energy provided by solar radiation at the surface over the period 00-24h local time per unit area and time (MJ/m^2/day).

  • Tdew: Mean dew point temperature at a height of 2 meters above the surface over the period 00h-24h local time (°C).

  • Uz: Mean wind speed at a height of 2 meters above the surface over the period 00h-24h local time (m/s).
