  ! 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.
