Re: SeaDAS not Reading Data

Thanks for sharing more detailed information. I did repeat your error reading A20192742019304.L3m_MO_CHL_chlor_a_4km.nc and AQUA_MODIS.20190101_20190131.L3m.MO.SST.sst.4km.nc. It's a known issue for SeaDAS 8.0.0 in reading files with null value attributes in metadata. The fix will be in the next rel...

Re: SeaDAS not Reading Data

The L3b file format is not a raster image format. The internal data model for SeaDAS is based on 2D raster images, so visualizing the L3b files is not directly possible. The data need to be mapped prior to display. You can use OCSSW -> l3mapgen to map L3b file to L3M file and read it. Here is the li...

Re: SeaDAS not Reading Data

Please tell us what version of SeaDAS are you using? SeaDAS-7.5.3 or SeaDAS 8.0.0?
Are you trying to read L2 data?
I am able to read A2019256071000.L2_LAC_OC.nc (MODIS AQUA 2019-09-13) and AQUA_MODIS.20190913T071001.L2.SST.nc with both versions of SeaDAS.

"Atmospheric correction is done by `l2gen` from the OCSSW processing system" as George said in another post. Here is the help page for l2gen https://seadas.gsfc.nasa.gov/help/8.0.0/processors/ProcessL2gen.html https://seadas.gsfc.nasa.gov/help/8.0.0/processors/ProcessL2gen.html#COMMAND_LIN...

Re: OCSSW: Remote server is down

From another post, I understand you are running SeaDAS 8.0.0, and trying to run l3mapgen.

If you click SeaDAS-OCSSW -> SeaDAS/System Info, it'll tell us more.

Thanks,

Re: Problems encountered by modis_L1A.py in processing moids L0 data

It seems to me that you have a network error. Maybe you can try modis_geo.py again when your network is more stable. Also, if you are not familiar with seadas-7.5.3, you can try our latest version SeaDAS 8.0.0 (Beta). It has same access to OCSSW and has more tools to help users to configure their en...

Re: Problems encountered by modis_L1A.py in processing moids L0 data

I was able to produce T2015137000500.GEO with OCSSW -> modis_GEO on T2015137000500.L1A_LAC on GUI. It's hard to tell what went wrong on your side. Could you please try to run modis_GEO on command line? 1) cd /home/ding/data/modis/003/ 2) /home/ding/seadas-7.5.3/ocssw/scripts/modis_GEO.py T2015137000...
