Use the las_fore.txt and par_fore.txt as a starting point DO NOT replace these files - make additional output files. So that the batch and "split" keeps on working, KEEP the par_fapp.txt and las_fapp.txt AS IS. Make two new append files with the diagnostics data HUMIDITY AND CLOUD COVER FORECAST FOR LA SILLA, CHILE. Forecast period starting at 12:00 on 2001.02.23 (day 54 of 2001).

Format change: Abbreviate heading line as follows (so we can condense): (UTC) | UTHavg UTHsig PWV TotCld OpqCld TraCld T.I. Round cloud percentages to one decimal place (show tenths) Get rid of the vertical line Add the following to the right of the existing data: Heading Description PixAll = Total number of pixels in the area PixOpq3 = Channel 3 image opaque pixel count for the area PixOpq4 = Channel 4 image opaque pixel count for the area PixTra = number of transparent pixels in the area UTHTrans = Average UTH for the transparent pixels (new computation - if transparent pixels are zero then "n/a") UTHMax = Maximum UTH value for clear pixels in the area (new computation - add this where you compute Avg UTH using CLEAR pixels only) Tir = the 10.7 micron channel average temperature (as now output for the batch version) SigTir = Std deviation of the 10.7 micron channel average temperature (as now output for the batch version) T400 = ECMWF 400mb temperature T500 = ECMWF 500mb temperature T600 = ECMWF 600mb temperature T700 = ECMWF 700mb temperature Tsfc = Surface temperature Tr = Temperature threshold for cloud detection U500 = U component of wind at 500mb U300 = U component of wind at 300mb V500 = V component of wind at 500mb V300 = V component of wind at 300mb current diagnostic files are available at: http://www.eso.org/astclim/forecast/meteo/ERASMUS/par_diag.txt http://www.eso.org/astclim/forecast/meteo/ERASMUS/las_diag.txt
