Conceptual Model (CM):Comma
(different types)
• MTP channels in comparison with the corresponding MSG channels
• CM: commas: IR image + relevant NWP parameters
• MSG additional channels + Channel combinations
• (WV and WV difference images)

MTP: ir
Co
As the image time between MTP and MSG differs, a shift between the cloud systems can be noticed in the two images

MSG: Ch10Visual inspection shows only very slight changes between Ch09 and Ch10;quantitative evaluation necessary
Co
9
MSG: Ch02
Compared to Ch01:no strong differences in the cloudfeatures;but: much better land recognition
Co

MSG: 129
Sharper contours and more detailed colour combinationsthrough improved space resolution in IR and additional information from 2 different VIS channels

MSG: Ch10

Looks relatively similar;but: somewhat coarser space resolution MSG: Ch01

MSG: Ch02
Compared to Ch01:no strong differences in the cloudfeatures over the ocean;but: much better land recognition

Grey shades: from Vis channelsCyan: represents the ice clouds from Ch03;cyan dominates the Co area;different shades within cyan showdifferent vertical structure of cells

MSG:321
CoGrey shades: from Vis channelsCyan: represents the ice clouds from Ch03;lots of grey cells visible through the dark cyan of the Co;cells and ice clouds are somewhat decoupled
