ancillary data, old or new

by melinfr » Wed Jul 06, 2022 10:59 am America/New_York

Dear Support,
when determining the ancillary data necessary for the processing of a MERIS file such as:
EN1_MDSI_MER_RR__1P_20020727T093846_20020727T102241_002123_0065_20180523T151615_0100.ZIP
getanc returns the former set of ancillary files, NCEP, EPTOMS, ... (it happens also with some OLCI files).
For other files, getanc returns the new set, with MERRA2 data.
This is quite puzzling and a problem in terms of consistency. Is this normal?
Thanks a lot for your help!
Best, F.

What tag of OCSSW are you using? This is what V2022.0 returns --

$ getanc /Users/*/Scenes/MERIS/forum/EN1_MDSI_MER_FRS_1P_20110303T145459_20110303T150439_047094_0097_20171225T172751_0100.SEN3/xfdumanifest.xml

Dear Bing,
thanks a lot for your reply. We have V2022 installed.
As said in the post, there are indeed cases for which getanc returns the MERRA met files. But this is not true for all. Please try the example file I mentioned in the post.
Best, F.

I tried EN1_MDSI_MER_RR__1P_20020727T093846_20020727T102241_002123_0065_20180523T151615_0100. It did not return MERRA MET files. Unfortunately, V2022.0 did not recognize EN1_MDSI_MER_RR__1P* as a MERIS file.

It's fixed and will be in the next V tag. R2022.4 and up has the fix. The latest is R2022.7

Dear Bing,
the problem with MERIS image is fixed.
We installed the R2002.8 version (the last available) and now getanc returns the correct MERRA ancillary files.

Anyway the same problem persists with OLCI data.
We tried with some files, both S3A and S3B, and getanc always returns the old ancillary files (below an axample):
S3A_OL_1_EFR____20210112T010238_20210112T010538_20210113T043433_0179_067_159_4140_LN1_O_NT_002.zip

sstfile=/oc01/software/seadas-8.2.0/ocssw/var/anc/2021/012/N2021012_SST_OIV2AV_24h.nc


*** WARNING: The following ancillary data types were missing or are not optimal: MET
*** Beware that certain MET and OZONE files just chosen by this program are not optimal.
*** For near real-time processing the remaining files may become available soon.

Is seems that MERRA ancillary files are not yet available.
Any suggestion or information?

Thank you in advance
Paolo

Thanks for reporting the issue. It's fixed. You should get MERRA ancillary files --

$ ocssw_runner --ocsswroot ~/ocssw getanc S3A_OL_1_EFR____20210112T010238_20210112T010538_20210113T043433_0179_067_159_4140_LN1_O_NT_002.SEN3/xfdumanifest.xml
