Daily Surface Meteorological Data (1982-2022) Extracted from AgERA5
Source:R/AgroClimateData.R
AgroClimateData.Rd
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).
