*********************************************************************** * * * notes: * * * * line-by-line data for gfdl and gsfc cases are derived from the * * air force geophysics lab catalog of lines. gfdl cases based on * * frequency bands from 0-3000 cm-1 use the 1982 version, and cases * * based on frequency bands from 0-2200 cm-1 use the 1980 version. * * gsfc uses the 1982 version. the ussr cases are derived from the * * kurchatov iae line-by-line data. * * * * bands are 10 cm-1 wide for gfdl cases and 5 cm-1 wide for gsfc * * and ussr cases. * * * * temperature profiles are from mcclatchy et al., 1971. for gfdl * * cases fitting of data to model levels is done by the "ptz" * * procedure (fels, 1986). * * * * the standard co2 volume mixing ratios used are 300 ppmv and * * 600 ppmv. * * * * the standard n2o volume mixing ratio used is 0.28 ppmv. * * * * tropopause level is as defined by the icrccm protocol. * * * * data levels are defined halfway between flux levels. * * * * the quantity g / cp used to calculate heating rate in k/day is * * 8.427 / 86400 (c-g-s units) for gfdl cases. * * * *********************************************************************** * * *
