An empirical relation for estimating global irradiation for Tennessee, U.S.A.
Long-term measured data on global irradiation on a horizontal surface, sunshine hours, air temperature, and relative humidity for two locations in the state of Tennessee (namely, Memphis and Nashville) have been used to obtain an empirical relation which may be used to estimate global irradiation for any location in the state. © 1992.
