1. INTRODUCTION
2022冬奥会开幕式1.1 Changes from Mod5.
2.0 to Mod5.2.1
Most changes in this revision are minor, such as correcting comments or removing unud source code. The more important changes are listed below:
Corrected error in calculation of spherical albedo term in <rootname>.acd file;
Corrected error in <rootname>.7sc brightness temperatures for nanometer bad respon functions;
Eliminated geometry problem most prevalent for line-of-sight paths that terminate near a tangent point;
Introduced the 2009 ries of band model parameter data bad on HITRAN2008 with 2009 updates.
Added the <rootname>.wrn output file which contains a duplicate listing of all warning and error
messages written to the <rootname>.tp6 and <rootname>.tp8 files;
Modified source for compatibility to GNU compilers and FORTRAN77; and
Eliminated DISORT scaling of thermal radiance contributions.
1.2 Changes from Mod5.
2.1 to Mod5.2.2
The number of changes in this revision is small, and they are delineated below:
Mod5.2.1 had an error in its treatment of the boundary term for down-looking radiance calculations
which ud DISORT multiple scattering; the nsor-to-ground attenuation was being modeled using
the true transmittance when the delta-M transmittance should have been ud. For particular
wavelength bins, spectral radiances could be in error by as much as a few percent.
MODTRAN *.tp6 output file lists the vertical and line-of-sight total path 550nm extinction optical
depths for molecular scattering, the aerosol components and cirrus clouds. For calculations in the
thermal infrared (TIR), for example, the visible wavelength optical depths are not particularly helpful.
MODTRAN *.tp6 output file now also lists the vertical and line-of-sight total path extinction optical
depths at the central frequency of the input spectral range for molecular scattering, the aerosol
components and cirrus clouds.
The MODTRAN headed, which previously was only written to the *.tp6 file, is now included in the
standard output and in the *.wrn file. The header has been modified to remind urs who obtain
MODTRAN via a Government Purpo U licen that their copy of the model is only to be ud for
Government Purpos as described in the licen. Finally, the header is now only written once to each
file.
MODTRAN now includes a frequently asked questions (FAQ) document. It is listed as Appendix G of

this document, but distributed in a parate volume.
1.3 Original Introduction
MODTRAN®[Berk et al., 1989; Berk et al., 1998; Berk et al., 2000] rves as the U.S. Air Force (USAF) standard moderate spectral resolution radiative transport model for wavelengths extending from the thermal Infrared (IR) through the visible and into the ultraviolet (0.2 to 10,000.0 m). The spectroscopy of MODTRAN®5.2.2 is bad on HITRAN2008 line compilation (Rothman et al., 1992; Rothman et al., 1998) with updates through June, 2009. The original MODTRAN® 1 cm-1 statistical band model was developed collaboratively by Spectral Sciences, Inc. and the USAF Rearch Laboratory to provide a fast alternative to the first principles, high accuracy line-by-line (LBL) radiative transport approach. Comparisons between MODTRAN® and LBL [Clough and Kneizys, 1979; Clough et al., 1981; Clough, 1988; and Snell et al., 1995]. Comparisons between MODTRAN® and the LBL model FASE (FASCODE for the Environment) [Clough et al., 1992; Cloug
h and. Iacono, 1995; Clough et al., 2005] spectral transmittances and radiances show agreement to within a few percent or better in the thermal IR. FASE shares its LBL line shape fitting algorithms with LBLRTM, which evolved from FASCODE; e, for instance, Clough et al., 1992; Clough and. Iacono, 1995; Clough et al., 2005]. The MODTRAN®model includes flux and atmosphere-scattered solar calculations, esntial components in analysis of near-IR and visible spectral region data that are not readily generated by LBL models.
Technical descriptions of the MODTRAN®5 approach are available from a variety of sources. The original MODTRAN®2 code and many of the MODTRAN®3 upgrades are described in the 1996 report "MODTRAN® 2/3
