MSG Correction for
The McIDAS-X 2013.1 tar file available on the 2013.1 Software
and Instructions page was updated 28 January 2013 at 21:30 UTC to include updated versions of
subroutines msgtaget2.for and msgtutil.for. The updated
subroutines contain a fix to give more precise temperature values for Meteosat-10 bands 4
through 11, and to support MSG Rapid Scan Service files. Note that the temperature errors were
generally small (up to +/-0.3 K were found during testing), and thus were not noticeable when
viewing the displayed data, though they may be important for users who need precise values.
Only those sites that maintain servers containing Meteosat-10 HRIT data or users with HRIT data
on their local workstation and need the precise IR temperature values and/or need the ability to use
local MSG Rapid Scan Service files need to install this update. All other users can skip this update.
Users who downloaded and installed McIDAS-X 2013.1 on their Unix workstation prior to 28 January 2013
21:30 UTC and need the precise IR temperature values and/or the ability to use local MSG Rapid Scan
Service files will need to install the updated msgtaget2.for and msgtutil.for
subroutines by completing the instructions below.
