polarization angle fix for binary files (move to end of binary file)

Opened this issue · 0 comments

Users have struggled with binary format spccoeff files that contain polarization angle information, because binary files are read sequentially, if a structure exists in the file being read in that is unexpected by older reading codes, it will fail. Moving the polarization angle structure to the end of the SpcCoeff files addresses this issue.

This fix will be retroactively applied to older CRTM releases, a new issue will be created in JCSDA/CRTM repository to cover this change. A new tag will be issued for each CRTM version (v2.4.0 (and emc variants), v2.4.1) to provide to impacted users.
The change is being made here (CRTM v3) so that it gets propagated into the future.
