! * Description: *
! * NG(IBAND) - number of g-values in band IBAND *
! * NSPA(IBAND) - for the lower atmosphere, the number of reference *
! * atmospheres that are stored for band IBAND per *
! * pressure level and temperature. Each of these *
! * atmospheres has different relative amounts of the *
! * key species for the band (i.e. different binary *
! * species parameters). *
! * NSPB(IBAND) - same for upper atmosphere *
! * ONEMINUS - since problems are caused in some cases by interpolation *
! * parameters equal to or greater than 1, for these cases *
! * these parameters are set to this value, slightly < 1. *
! * PAVEL - layer pressures (mb) *
! * TAVEL - layer temperatures (degrees K) *
! * PZ - level pressures (mb) *
! * TZ - level temperatures (degrees K) *
! * LAYTROP - layer at which switch is made from one combination of *
! * key species to another *
! * COLH2O, COLCO2, COLO3, COLN2O, COLCH4 - column amounts of water *
! * vapor,carbon dioxide, ozone, nitrous ozide, methane, *
! * respectively (molecules/cm**2) *
! * CO2MULT - for bands in which carbon dioxide is implemented as a *
! * trace species, this is the factor used to multiply the *
! * band's average CO2 absorption coefficient to get the added *
! * contribution to the optical depth relative to 355 ppm. *
! * FACij(LAY) - for layer LAY, these are factors that are needed to *
! * compute the interpolation factors that multiply the *
! * appropriate reference k-values. A value of 0 (1) for *
! * i,j indicates that the corresponding factor multiplies *
! * reference k-value for the lower (higher) of the two *
! * appropriate temperatures, and altitudes, respectively. *
! * JP - the index of the lower (in altitude) of the two appropriate *
! * reference pressure levels needed for interpolation *
! * JT, JT1 - the indices of the lower of the two appropriate reference *
! * temperatures needed for interpolation (for pressure *
! * levels JP and JP+1, respectively) *
! * SELFFAC - scale factor needed to water vapor self-continuum, equals *
! * (water vapor density)/(atmospheric density at 296K and *
! * 1013 mb) *
! * SELFFRAC - factor needed for temperature interpolation of reference *
! * water vapor self-continuum data *
! * INDSELF - index of the lower of the two appropriate reference *
! * temperatures needed for the self-continuum interpolation *
! * *
! * Data input *
! * COMMON /Kn/ KA(NSPA(n),5,13,MG), KB(NSPB(n),5,13:59,MG), SELFREF(10,MG) *
! * (note: n is the band number) *
! * *
! * Description: *
! * KA - k-values for low reference atmospheres (no water vapor *
! * self-continuum) (units: cm**2/molecule) *
! * KB - k-values for high reference atmospheres (all sources) *
! * (units: cm**2/molecule) *
! * SELFREF - k-values for water vapor self-continuum for reference *
! * atmospheres (used below LAYTROP) *
! * (units: cm**2/molecule) *
