Hello again,
I need to make a small correction to the details of the *brfPrf* product,
see below:
*Example LDM pattern-action file action:*
EXP spireert/level2/bfrPrf/([0-9]{4}).([0-9]{3})/(bfrPrf.*_nc)
FILE -close -overwrite
/data/ldm/pub/native/COSMIC/spireert/bfrPrf/\3
should be changed to this:
*Example LDM pattern-action file action:*
EXP spireert/level2/bfrPrf/([0-9]{4}).([0-9]{3})/(bfrPrf.*_bufr)
FILE -close -overwrite
/data/ldm/pub/native/COSMIC/spireert/bfrPrf/\3
The only difference is the end of the file name for the pattern, _nc should
have been _bufr. Sorry about that!
Best,
-Mike
