VIIRS Polymer Processing

Post by naarring »

I am working on atmospherically correcting VIIRS data through Polymer. I have run the L1A images through SeaDAS to get the L1C image, and then running the L1C image through polymer, using the code:
run_atm_corr(Level1_VIIRS(l1),
Level2_NETCDF(outdir=viir_outdir))

The return I get is:
Trying to download https://oceandata.sci.gsfc.nasa.gov/cgi ... MI_24h.hdf ...
Trying to download https://oceandata.sci.gsfc.nasa.gov/cgi ... 6h.hdf.bz2 ...

(The dates change based on image date)

This is then followed by:
Starting processing at 2023-02-15 15:43:38.833234
Initializing output file "/media/naarring/f043a704-2f01-4837-bac9-1bda936ead16/Nate/BBP_L2/Polymer/SNPP_VIIRS.20130826T183000.L1C.nc.nc"

The process finishes without the images being corrected or any clear error message. Is there something I'm missing? I used this code a month ago, which worked just fine. But it seems to not be working now. Any thoughts on what the issues(s) could be?

Hi,
Indeed the code should not stop all of a sudden like that. It should end with "Done in <elapsed time>".
Very surprising that you see no message at all, at least a python error should be risen.
Could you try with another image ? Do you see anything in the system logs ?
Cheers, François
