real(kind=kind_phys), dimension(ng03, mfr03), public forref
 the array forref contains the coefficient of the water vapor foreign-continuum (including the energy term). the first index refers to reference temperature (296,260,224,260) and pressure (970,475,219,3 mbar) levels. the second index runs over the g-channel (1 to NG03=16).
 
real(kind=kind_phys), dimension(ng03, msa03), public absa
 the array absa(NG03,585) = ka(NG03,9,5,13) contains absorption coefs at the NG03=16 g-intervals for a range of pressure levels > ~100mb, temperatures, and ratios of water vapor to co2. the first index in the array, js, runs from 1 to 9, and corresponds to different water vapor to co2 ratios, as expressed through the binary species parameter eta, defined as eta = gas1/(gas1+(rat)*gas2), where rat is the ratio of the reference mls column amount value of gas1 to that of gas2. the 2nd index in the array, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 1-5 means that the data are for the corresponding temperature of tref-30, tref-15, tref, tref+15, and tref+30, respectively. the third index, jp, runs from 1 to 13 and refers to the reference pressure level (e.g. jp = 1 is for a pressure of 1053.63 mb). the fourth index, ig, goes from 1 to NG03=16, and tells us which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(ng03, msb03), public absb
 the array absb(NG03,1175) = kb(NG03,5,5,13:59) contains absorption coefs at the NG03=16 g-intervals for a range of pressure levels < ~100mb, temperatures, and ratios of h2o to co2. the first index in the array, js, runs from 1 to 5, and corresponds to different gas amount ratios, as expressed through the binary species parameter eta, defined as eta = gas1/(gas1+rat*gas2), where rat is the ratio of the reference mls column amount value of gas1 to that of gas2. the second index, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 1-5 means that the data are for the corresponding temperature of tref-30, tref-15, tref, tref+15, and tref+30, respectively. the third index, jp, runs from 13 to 59 and refers to the reference pressure level (e.g. jp = 13 is for a pressure of 95.5835 mb). the fourth index, ig, goes from 1 to NG03=16, and tells us which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(ng03, msf03), public selfref
 the array selfref contains the coefficient of the water vapor self-continuum (including the energy term). the first index refers to temperature in 7.2 degree increments. for instance, jt = 1 refers to a temperature of 245.6, jt = 2 refers to 252.8, etc. the second index runs over the g-channel (1 to NG03=16).

 planck fraction mapping level: p=212.7250 mbar, t = 223.06 k
 
real(kind=kind_phys), dimension(ng03, mbf03), public fracrefb
 planck fraction mapping level: p = 95.8 mbar, t = 215.7 k
 
real(kind=kind_phys), dimension(ng03, maf03, mmn03), public ka_mn2o
 the array ka_mxxx(NG03,9,19) contains the absorption coefficient for a minor species at the NG03=16 chosen g-values for a reference pressure level below 100~ mb. the first index in the array, js, runs from 1 to 9, and corresponds to different gas column amount ratios, as expressed through the binary species parameter eta, defined as eta = gas1/(gas1 + (rat) * gas2), where rat is the ratio of the reference mls column amount value of gas1 to that of gas2. the second index refers to temperature in 7.2 degree increments. for instance, jt = 1 refers to a temperature of 188.0, jt = 2 refers to 195.2, etc. the third index runs over the g-channel (1 to NG03=16).
 
real(kind=kind_phys), dimension(ng03, mbf03, mmn03), public kb_mn2o
 the array kb_mxxx contains the absorption coefficient for a minor species at the NG03=16 chosen g-values for a reference pressure level above 100~ mb. the first index in the array, js, runs from 1 to 10, and corresponds to different gas column amounts ratios, as expressed through the binary species parameter eta, defined as eta = gas1/(gas1 + (rat) * gas2), where rat is the ratio of the reference mls column amount value of gas1 to that of gas2. the second index refers to temperature in 7.2 degree increments. for instance, jt = 1 refers to a temperature of 188.0, jt = 2 refers to 195.2, etc. the third index runs over the g-channel (1 to NG03=16).
