radiação solar global, difusa e direta, modelos de estimativa de Liu & Jordan e AngstromResumo
O trabalho apresenta equações de estimativa e a validação para as radiações global, di- reta na horizontal e difusa em função da razão de insolação (n/N) e índice de claridade ( K T ) utili- zando os modelos de Angstrom e Liu-Jordan, respectivamente.
