Abstract

We verified the validity of the downward longwave radiation equation by Kondo et al.(1991) using the high-accurate BSRN radiation data observed at the five meteorological stations in Japan. The following facts were noted. 1)The original downward longwave radiation equation shows a root mean square error of 8.8 W/m2 at the five BSRN stations and tends to underestimate all the year round at the Tateno station. 2)The downward longwave radiation equation with recalibrated parameters gives a root mean square error of 8.3 W/m2. 3)Because the recalibration effect is limited, it is likely that parameters of the original longwave radiation equation are widely applicable except a winter season at Tateno station.
