Read reanalysis data — gr_read

The function reads meteorological variables (temperature and precipitation) from grwat reanalysis for using with gr_join_rean(). Reanalysis covers the East European Plain with 0.75 degrees spatial resolution and is obtained based on CIRES-DOE (1880-1949) and ERA5 (1950-2021) data.

Usage

gr_read_rean(file_prec, file_temp)

Arguments

file_prec: Character string path to precipitation NetCDF file.
file_temp: Character string path to temperature NetCDF file.

Value

list containing time series, precipitation series, temperature series and spatial points (sf)
