Areal statistics will be produced for selected 25 GOP defined areas (http://gop.meteo.uni-koeln.de/gop/) Statistics MSG for the various areas at 15 min resolution (see below) Mean, median and standard deviation of brightness temperatures for all 8 IR MSG channels - probability density function (20 classes, min=180, max=350) for each of the 8 IR MSG channels Mean cloud coverage and mean cloud area fraction - probability density function (20 classes, min=0, max=1) for cloud probability Mean, median and standard deviation of cloud top pressure - probability density function (20 classes, min=0, max=1020) for cloud top pressure Mean, median and standard deviation of integrated_water_vapor - probability density function (20 classes, min=0, max=10) for integrated_water_vapor
