attribute NC_GLOBAL comment String ---------- TO RE-MAP EQUAL-AREA MAP TO EQUAL-ANGLE (SQUARE LON,LAT) MAP ---------- For display purposes, the ISCCP equal-area map may be converted to an equal-angle map using replication. The variables 'eqlat_index', 'sqlon_beg' and 'sqlon_end'are provided for this purpose. Each equal-area cell is replicated into a specific range of longitude cells in the equal-angle map. For example, to remap an equal-area array eqvar[41252] to an equal-angle array sqmap[360,180], each eqvar[i] should be replicated into the range of cells indicated by sqlon_beg[i] and sqlon_end[i], and the lat index eqlat_index[i]. Using Fortran notation the assignment is: sqmap[sqlon_beg[i]:sqlon_end[i], eqlat_index[i]] = eqvar[i]. ---------- TO CONVERT COUNT UNITS TO PHYSICAL UNITS ---------- When attribute conversion_table is present for any variable, the reported values of count units may be converted to physical quantities by using the specified conversion table variable as a look-up table whose index is count value 0-255. For example, temperature = tmptab(count), temperature_variance = tmpvar(count), pressure = pretab(count), reflectance = rfltab(count), optical_depth = tautab(count), ozone = ozntab(count), humidity = humtab(count), water_path = wpatab(count). ---------- DEFINITION OF CLOUD TYPES ---------- VIS/IR cloud types are defined by a histogram of cloud top pressure and cloud optical depth, for both liquid and ice clouds. IR cloud types are defined by a histogram of cloud top pressure. Identification labels for the 18 VIS/IR cloud types and the 3 IR cloud types are given in the 'cloud_type_label' and 'cloud_irtype_label' variables, which correspond to the order of the cloud type variable arrays. ---------- TO COMPUTE CLOUD TOP HEIGHT ---------- Cloud top height in meters may be computed by applying lapse rate to the difference between cloud top temperature and surface temperature. Given rlapse 6.5, the formula is: height_meters = (ts - tc) / rlapse * 1000.0. ---------- TO COMPUTE TOTAL IR BRIGHTNESS TEMPERATURE ---------- Using IR cloud/clear categories: n_ir_clear = n_total - n_ir_cloudy, and then total_ir_bt = ( (n_ir_cloudy * ir_ircloudy) + (n_ir_clear * ir_irclear) ) / n_total, where ir_ircloudy and ir_irclear are values of count units. The resulting total_ir_bt can be converted from count units to physical units using the tmptab conversion table. Using VIS/IR cloud/clear categories: n_clear = n_total - n_cloudy, and then total_ir_bt = ( (n_cloudy * ir_visircloudy)+ (n_clear * ir_visirclear) / n_total, where ir_visircloudy and ir_visirclear are values of count units. The resulting total_ir_bt can be converted from count units to physical units using the tmptab conversion table. ---------- TO COMPUTE TOTAL VIS RADIANCE ---------- Using IR cloud/clear categories: n_ir_clear = n_total - n_ir_cloudy, and then total_vis_radiance = ( (n_ir_cloudy * vis_ircloudy) + (n_ir_clear * vis_irclear) ) / n_total. Using VIS/IR cloud/clear categories: n_clear = n_total - n_cloudy, and then total_vis_radiance = ( (n_cloudy * vis_visircloudy)+ (n_clear * vis_visirclear) / n_total.
