Hello everyone, newbie here and Happy New Year to all.

URL: https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-2/Aqua-MODIS/2025/

1. We program in Wolfram Programming Language (cloud version) and I am able to open and read the .nc file in the URL above. All is good!

2. I need a master key-list for all the available polygons for this particular attribute namely "/geophysical_data/chlor_a". I now I am able to read the lat/log from the file itself but the file name itself only encodes the time and the date!

3. For such a particular attributes again the "/geophysical_data/chlor_a" how can I do a search say for past 4 weeks, if possible for a particular polygon (if this makes any sense)

4. See my attached rendering of the actual grid data (pixels), can you help me with the color table please?

In case I am missing on the proper way of asking questions , please be patient and I shall catch up soon!
