The effect of the surface albedo is considered secondly as an error correction so as to obtain the net solar radiation at various surface albedos .

Solar radiation is the foremost source of energy for Earth climate, so a minor error in calculation of the heating rate about short wave radiation may cause a prodigious mistake in climate modeling.

This paper presents the applications of Model ZR-2 comprehensive telemetering recorder for solar radiation and its properties, design principles, error analysis and features of the circuits.
