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...

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...

Apologies if this question appears twice - it's not clear if the initial submission went through. I have also made posts that seem to have vanished. I think your basic question has been answered, but I assume you are using Python to script batch processing, so plan to run l2gen many times. One thin...

Two things to consider: When working with a mix of Windows and Linux, it is best to stick with simple directory names: no spaces or "special" characters. Your example has both a <space> character and a <single_quote> character. The Virtual machine instructions are for a "headless"...

Can you try /Users/bcollist/opt/anaconda3/bin/python3 -m pip install requests You need Python requests package v2.18.0 or later With anaconda python you should use: https://anaconda.org/anaconda/requests (currently shows version 2.23 for macOS). Note that using anaconda python by setting only the P...

Has any more progress been made on this issue? This isn't something that can be fixed in SeaDAS. Apple recommends that users avoid using the "system" python for applications because that usually requires changes to the installed packages. It is up to the user to ensure that the SeaDAS req...

I doubt there is any reliable shortcut -- just follow NASA's instructions. If you stick with the same compiler versions NASA uses you should not encounter the problems that arise using different OS's. The build uses CMake, which does rather extensive checking to for the required libraries and header...

As I need to run SeaDAS processing SW with some modifications, for research purposes, I'd need to modify some C source programs and recompile l2gen executable. Is it possible to get somewhere the makefile or any other instruction to recompile l2gen (or all the SeaDAS processing executable)? See: ht...

Using these in the extractor on the L1A file appeared to work, but when processed up to L2, it's the wrong region (and must be over all cloud). Even if it had worked that way, the approach sort of defeats my objective to reduce processing time and disk usage by subsetting prior to processing L1B/L2...

https://seadas.gsfc.nasa.gov/requirements/ says MacOS distributions include a suitable Java JRE, but that may be outdated. A recent JRE such as the one in the link you mention will be widely used, so any Big Sur problems should be found and fixed. SeaDAS uses the SNAP Java GUI, but ESA SNAP support...
