After a longer period of mostly convincing Live weather depiction today was a bit disappointing:
EDDH in the sim:
EDDH seen from a webcam in the vicinity (airport is straight ahead):
While not totally unreasonable considering the actual METAR report at that time (EDDH 191050Z AUTO 21013KT 9999 BKN010 03/01 Q1000 TEMPO BKN007) , it lacks in terms of overall cloud coverage and visibility.
I think further improvements could be made by always using the weather model with the best resolution for a given area, as the ICON model for instance has it more accurate for Germany than NEMS (alledgedly used in MSFS):
ICON (couldn’t get MB website to display the 12:00 picture):
NEMS:
And regarding the visibilty I am under the impression that the available data is not implemented at all, as even the NEMS data show visibilty in the 10 to 15 km range in the area:
Instead, the sim showed unlimited visibility:
So the blending process of the “9999” value in the METAR should consider the surrounding visibilty data from the forecast model - ideally the one with the best possible resolution for any given area.
