3. the JasPer library must be available as a shared library If you build JasPer from source add enable shared to the JasPer configure command This is only relevant when ACPG is built with GRIB API and not EMOS we have no GRIB2 files available yet containing the ECMwF extended model levels therefore we can not guarantee that processing on such files will work If needed a patch will be released after files have been made available For other open issues and disclaimers see release_note_2010 Page 5
4. oj or numpy are not located in standard places The CMSAF changes are mainly all processing both gac and not gac In cloudmask mountain schemes Additional caution test for very cold surfaces added for avoiding ridiculous results over Greenland and Antarctica Stop single temperature difference tests if tsurf lt 230 K In cloudmask Stop processing a pixel if both channel 3 and 4 is missing Before it stopped if channel 3 was missing This gives product data in areas where it was missing before GAC only added options for noaa 19 and metop 02 new way of calculating azimiuth differences Page 1 release_note_2010_patch1 txt Changes to GAC interface with respect to handling of scanlines LAC only i f new way calculating solar azimuth Configurable GAC not GAC See also section 6 For texture calculations in cloudmask and cloudtype kernel size made configurable 5 used for not gac as before 3 used for gac a special threshold offset file for GAC the old one for not gac The USE_T37T12_MOUNTAIN_TEST will turn ON OFF the test brightCloudTest in case of being all of day land mountain and channel 3b is existing Having the test on gives better performance in high and flat terrain like Antarctica and therefore best suits the CMSAF needs Having the test off gives better performance in high and rough terrain like the Alps and the Scandinavian mountains and therefore best suits the needs of European no
