This interim technical report describes a new band-model formulation for the LOWTRAN 6 atmospheric transmittance/radiation computer code. Band-model parameters for H/sub 2/O, CO/sub 2/, O/sub 3/, CO, CH/sub 4/, O/sub 2/, and N/sub 2/ were calculated using the 1986 HITRAN line atlas. They were calculated for 1 /cm bins from 0 - 17,900/cm and at five temperatures from 200 to 300K. This transmittance model and associated subroutines were integrated into LOWTRAN 6. The spectral resolution of this new option is better than 5/cm (FWHM). A preliminary version of the code was delivered to AFGL for testing. Validation against FASCOD2 calculations will be the emphasis for the remainder of this effort.
