Re: l2gen not using specific settings

I think V2022.0 uses the new https://oceancolor.gsfc.nasa.gov/docs/f ... onvention/, so is not a drop-in replacement for existing workflows.

Re: OCSSW Installation error

You appear to be using Python 3.5. https://seadas.gsfc.nasa.gov/requirements/ states that you need Python 3.6 or above. Note that you may also need to install a suitable python3-requests package. When asking for help it is good practice to mention your OS version because others using the same OS ver...

Question: How to convert zero value to NaN in SeaDAS

Re: How to convert zero value to NaN in SeaDAS

SeaDAS has built-in support for missing value handling (see the properties for your new band). NaN's are commonly used with floating point data, but if your generated band uses integer values, your only option is to set a missing value in the band properties. If you use NetCDF4-CF format, missing va...

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...

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

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. ...
