Package: BrazilMet 0.5.0

BrazilMet: Download and Processing of Automatic Weather Stations (AWS) Data of INMET-Brazil

A collection of functions for downloading and processing automatic weather station (AWS) data from INMET (Brazil’s National Institute of Meteorology), designed to support the estimation of reference evapotranspiration (ETo). The package facilitates streamlined access to meteorological data and aims to simplify analyses in agricultural and environmental contexts.
