Re: VIIRS striping and M1/M2 band comparisons to MODIS
The short answer is yes, the temporal calibration (including detector/mirror-side striping) will be much improved with the upcoming reprocessing for VIIRS (on both SNPP and NOAA-20). So, also yes, what you're seeing is instrument artifacts in VIIRS. MODIS-Aqua is next up in the reprocessing hopper, ...

Re: File Search broken ?
We are investigating, but the problem is not consistent so diagnosing it is proving a challenge. Stay tuned.

Re: MODIS/Terra Availability
There was an issue with a distribution server upstream from us that prevented us from getting the data. That issue is resolved and we should be caught up with the data ingest/processing soon.

Re: Hawkeye processing with MUMM
Yes, the code works with Hawkeye...hasn't been evaluated with it, but it doesn't blow up, so that's a good sign

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.

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.

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...
