sr_tair_calculation

If global radiation is not measure at station, it can be estimated with this function.

A compilation of functions to download and processing AWS data of INMET-Brazil, with the purpose of reference evapotranspiration (ETo) estimation. The package aims to make meteorological and agricultural data analysis more parsimonious.
