Solar energy measurement program at Hampton, Virginia

A global, diffuse and direct solar irradiance and atmospheric emittance measurement program was initiated February 1981 at Hampton, Virginia. Measurements of cloud cover fraction and atmospheric turbidity were also routinely made. The results of the correlation of global insolation with cloud cover fraction using the ARL regression equation are presented for the period March 1981 through February 1982. Mean daily insolation components are also presented for the period March 1981 through December 1982.
