103 : ! * Description: *
104 : ! * NG(IBAND) - number of g-values in band IBAND *
105 : ! * NSPA(IBAND) - for the lower atmosphere, the number of reference *
106 : ! * atmospheres that are stored for band IBAND per *
107 : ! * pressure level and temperature. Each of these *
108 : ! * atmospheres has different relative amounts of the *
109 : ! * key species for the band (i.e. different binary *
110 : ! * species parameters). *
111 : ! * NSPB(IBAND) - same for upper atmosphere *
112 : ! * ONEMINUS - since problems are caused in some cases by interpolation *
113 : ! * parameters equal to or greater than 1, for these cases *
114 : ! * these parameters are set to this value, slightly < 1. *
115 : ! * PAVEL - layer pressures (mb) *
116 : ! * TAVEL - layer temperatures (degrees K) *
117 : ! * PZ - level pressures (mb) *
118 : ! * TZ - level temperatures (degrees K) *
119 : ! * LAYTROP - layer at which switch is made from one combination of *
120 : ! * key species to another *
121 : ! * COLH2O, COLCO2, COLO3, COLN2O, COLCH4 - column amounts of water *
122 : ! * vapor,carbon dioxide, ozone, nitrous ozide, methane, *
123 : ! * respectively (molecules/cm**2) *
124 : ! * FACij(LAY) - for layer LAY, these are factors that are needed to *
125 : ! * compute the interpolation factors that multiply the *
126 : ! * appropriate reference k-values. A value of 0 (1) for *
127 : ! * i,j indicates that the corresponding factor multiplies *
128 : ! * reference k-value for the lower (higher) of the two *
129 : ! * appropriate temperatures, and altitudes, respectively. *
130 : ! * JP - the index of the lower (in altitude) of the two appropriate *
131 : ! * reference pressure levels needed for interpolation *
132 : ! * JT, JT1 - the indices of the lower of the two appropriate reference *
133 : ! * temperatures needed for interpolation (for pressure *
134 : ! * levels JP and JP+1, respectively) *
135 : ! * SELFFAC - scale factor needed for water vapor self-continuum, equals *
136 : ! * (water vapor density)/(atmospheric density at 296K and *
137 : ! * 1013 mb) *
138 : ! * SELFFRAC - factor needed for temperature interpolation of reference *
139 : ! * water vapor self-continuum data *
140 : ! * INDSELF - index of the lower of the two appropriate reference *
141 : ! * temperatures needed for the self-continuum interpolation *
