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

"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: SeaDAS 8 install_OCSSW problem with python requests

Don't worry about "Environment {$OCSSWROOT} (external): null WARNING!: An environment variable for OCSSWROOT exists which does not match the GUI configuration. The GUI will use '/Users/daurin/Applications/seadas8/ocssw' as the ocssw root inside the GUI." SeaDAS/System Info is trying to fig...

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...

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...

Question: unexpected exception

Re: unexpected exception

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 A20203362020366.L3b_MO_CHL.nc, and then open A20...

Re: unexpected exception

It means that you are trying to open a file and there is something in the file that SeaDAS does not like. It might be helpful if you could tell us what file you tried to read?

The file corresponds to MODOOF.A2015137.1415.20151380602.001.PDS is MOD00.A2015137.1415_1.PDS. You need to download MOD00.A2015137.1415_1.PDS.bz2 and uncompress it as Sean said.

Also, please choose T instead of A for mission.

Re: 'Minimum must not be infinity' in mosaiccing product generated by gpt.sh

Could you please share your xml file?

I did l2gen on A2008209061500.L1B_LAC without using subsetting options. There is no data in the region (27.65,100.73,27.76,100.85), assuming (south, west, north, east). I was not able to do l2gen on A2008209061500.L1B_LAC with the given subset config.
