地球大気向け長波放射モデル Ver. 2.4

long wave radiation model for the Earth‘s atmosphere Ver. 2.4

Note that Japanese and English are described in parallel.

長波放射モデル.

This is a model of long wave radiation for the Earth‘s atmospehre. Radiation in the wavenumber range from 0 to 3000 cm-1 is calculated following the scheme by Chou et al. (2001). But absorptions by CFC and weak bands desinated as band 10 in Chou et al. (2001) are neglected.
