Re: SEADAS OCSSW issues on Windows

If you need a prompt response you should do everything possible to make it easy for others to understand and reproduce your problem. This means providing your OS('s), SeaDAS, and OCSSW l2gen versions. Please post your client/server configuration files. Have you verified that the linux installation p...

This means providing your OS('s), SeaDAS, and OCSSW l2gen versions, the VIIRS L1 filename, and the details of your level-2 processing (ancillary data, l2_prod list, ou...

Re: I have problem about extracting multiple NetCDF files with multiple stations of interest

I attempted to utilize seaDAS at first, but because of my laptop's window operating system, I was unable to use the extraction feature. Thanks for the additional detail. I think pixel extraction should work in the SeaDAS GUI, but a laptop may not have the capacity (mainly RAM) to process many files...

Re: L2gen fail with exit code 1

I had no problem processing the same granule to generate GEO and L1B files, download ancillary files, and then L2_LAC files for "l2prod=chlor_a", but got exit code 139 for "l2prod=chlor_a,sst_triple". The "sst_triple" algorithm is for VIIRS, and only works for night tim...

Re: I have problem about extracting multiple NetCDF files with multiple stations of interest

Glad you found success. I assume you have previous experience with R. For the benefit of the next person with the same question, it might be helpful to provide a brief outline of your workflow.

Re: I have problem about extracting multiple NetCDF files with multiple stations of interest

So, how do I use seaDAS to combine all 365 files and extract all stations at once? If you have, could you kindly let me know if you have any tutorial links or documentation on how to combine and extract? It would be extremely helpful. SeaDAS focuses on the specific needs of ocean color processing. ...

Re: 'Connection to urs.earthdata.nasa.gov timed out.

Such glitches are often transient, so you should try a few times over a 24-hour period. Meanwhile, you could check the version of your Python requests package (python -m pip list | grep requests) against the current OCSSW requirements. https://stackoverflow.com/questions/23013220/max-retries-exceede...

Re: Errors in building ocssw processing executables

You appear to be using documentation from an old version. https://seadas.gsfc.nasa.gov/downloads/ has instructions for the current "--tag V2021.2" version. Somewhere in the documentation there is a note that sources for VIIRS support have not been released, so you need to download an archi...

Re: Seadas batch processing: Extracting l2flags and szen

For comparisons with in situ data I would use unmapped level-2 pixels in some region around the in situ location for a pass within a time window around the time of the in situ measurement. Unwanted/dubious pixels can be excluded using flags, and you can cosider the distribution of satellite values i...

Re: Seadas batch processing: Extracting l2flags and szen

Today is the US Thanksgiving Holiday, but from Canada I can try to answer: Mapping software is generally restricted to variables that can take on a continuous range of values. Flags and classification data have discrete values. Mapping requires assigning values of the variable by some form of interp...
