They're now called something like
atmPhs_MTPB.2013.151.15.59.G32_2010.2640_nc
with the global attribute
fileStamp = "MTPB.2013.151.15.59.G32"
which defines
leo_id = "MTPB"
This fails the ropp_pp GRAS data identification tests, which looks for
leo_id = "ME??".
So ropp_pp won't carry out GRAS-specific processing on these data.
Solution: look for "MT??" as well.
These changes have been incorporated in (the f90 bits of) r4210.
Note that although ropp_pp_occ_tool now recognises (eg) atmPhs_MTPB.2013.151.15.59.G32_2010.2640_nc as GRAS data, it still fails to process it, because there aren't enough data points:
It's like this in all the CDAAC GRAS datasets I've looked at.
Open #371 ('whenever') to look into this. Meanwhile, close this ticket for ROPP8.0.
