dcpam 地球大気向け放射モデル Ver. 2

dcpam radiation model for the Earth‘s atmosphere Ver. 1

Note that Japanese and English are described in parallel.

地球大気向け放射モデル.

This is a radiation model for the Earth‘s atmospehre.

Radiation in the wavenumber range from 0 to 3000 cm-1 is calculated in the routine of long wave radiation. Radiation in the wavenumber range from 1000 to 57143 cm-1 (0.175 to 10 micron) is calculated in the routine of shortwave radiation.
