Question: l3bin additional

Re: l3bin additional

The error message was reporting the line in the code where the error occurred. The reported path to that source code has nothing to do with where the code resides on your machine - and it is not trying to put anything on your machine under that path. The permission denied part is the return from the...

Re: l3bin additional

Check your output directory permissions. The line in the code that is reporting "Permission denied" is the line that creates the output file. It's dying because it cannot do so for permission reasons.

Question: VIIRS Rrs values in the IR

Re: VIIRS Rrs values in the IR

While Bing's response is correct, you should bear in mind that unless you change the bands used in the aerosol selection process, the Rrs in the NIR channels will not be "measured", but rather the output of the model used in the "NIR-correction" algorithm.

Question: Regarding the switching threshold for NIR-SWIR AC

Re: Regarding the switching threshold for NIR-SWIR AC

No, you cannot pass a parameter to l2gen to modify the Shi and Wang NIR/SWIR switching algorithm to use an Rrs_645 threshold in place of the turbidity index.

If you process both SWIR and NIR in separate runs you can use SeaDAS' Math Band operator to blend the output.

Re: ‘p’ is not recognized as an internal or external command, operable program or batch file when using wget on Windows1

Seems the "p" is incorrectly being interpreted as a command line option to wget. Try putting the URL in quotes, e.g.: wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on --no-check-certificate --content-disposition -i "https://oceandata.sci.gsfc.nas...

Question: Processing SGLI with SeaDAS
Replies: 7

Re: Processing SGLI with SeaDAS

l2gen derives the IRS filename from the input VNR file (it's a simple string substitution), so there is no parameter for passing the IRS filename. Sure, not ideal, as filename can lie (well, not match the expected pattern). In your run, l2gen is complaining that "GC1SG1_202205260207P05515_1BSN_...

Re: SeaDAS Tiff 8-bit

Mike,

To get floating point values in the TIFF output from l3mapgen, set 'apply_pal=no' (or false, or 0).

Re: How to download global VIIRS L1A and geo data?

Elaine, The documentation on the "ProcessGeolocate_viirs" page needs to be updated (thanks for alerting us to that discrepancy). The required DEM files are no longer distributed using the samoa FTP server (it, in fact, no longer serves as an FTP server - as we no longer support FTP distrib...
