Thanks for reporting the issue. getanc.py(SeaDAS -7.5) and getanc(V2022.0) are returning a new set of ancillary files. The new filenames do not start with "NYYYY...", and getanc.py and getanc have trouble recognizing them. The bug was fixed. getanc will behave right in the next tag of OCSS...

I don't know if you are familiar with SeaDAS -- a comprehensive software package for the processing, display, analysis, and quality control of ocean color data. https://seadas.gsfc.nasa.gov/ You can use l3mapgen to reproject an L3b file to an L3m file and open it with SeaDAS --https://seadas.gsfc.na...

You can do reprojection on command line -- https://seadas.gsfc.nasa.gov/help-8.2.0/GptCookbook/gptCookbookReproject.html

Here is the GPT tutorial -- https://seadas.gsfc.nasa.gov/help-8.2.0/GptCookbook/gptTutorial.html

So MODIS_2008097_SWIR.hdf is the L2 file created by l2gen? What SeaDAS tool did you use to create the tiff file MODIS_2008097.tif?

Are you able to use the reproject tool in SeaDAS to create the GeoTiff file? https://seadas.gsfc.nasa.gov/help-8.2.0/desktop/Reprojection.html

I replicated your problem. Please make sure that your "selected products" on the "Products" tab in the l2gen GUI does not include nLw (nLw_1238 nLw_1604 nLw_2258 nLw_746 nLw_868 nLw_vvv are fine). Mine looks like this -- Kd_490 Rrs_vvv angstrom aot_868 chlor_a nLw_1238 nLw_1604 n...

There is no such file AQUA_MODIS.20220810T123501.L1A.OC.NRT.nc in our system. Downloadable MODIS L1A file is still using the old naming convention on our site-- See https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-1A/Aqua-MODIS/2022/222/ You should use fileL2=A2022222123500.L1A_LAC.bz2 in ...

Please let us know where you downloaded AQUA_MODIS.20220810T123501.L1A.OC.NRT.nc, so we can replicate the error.

What tag of OCSSW are you using? I can do l2gen on V2019216051800.L1A_SNPP.nc and V2019216051800.GEO-M_SNPP.nc successfully with V2022.0

Sorry that SeaDAS-8.2.0, as well as SNAP, does not support the Time Series tool.

Do you have GC1SG1_202005030219J06710_1BSG_IRSDQ_2000.h5 in the same directory with GC1SG1_202005030219J06710_1BSG_VNRDQ_2000.h5?

You need to have IRSDQ file in the same directory as the VNRDQ file. Hope this post can be helpful. viewtopic.php?t=3180
