NASA_Satellite_Maps

In this script, I create maps with MODIS-Aqua data, but you can modify the script for a different NASA satellite.

About ESA vs. NASA data structures

ESA and NASA use different data structures. NASA stores all parameters in one NetCDF file, while ESA stores each parameter in a separate NetCDF.

How to set up working directory:

Download M_map (https://www.eoas.ubc.ca/~rich/map.html) and move to functions folder. Store Level-2 images (NetCDFs) in data folder.

Obtaining Level-2 Data

Options:

download Level-2 directly, already processed by NASA (OK for open ocean, Case I waters) -- I recommending using getOC: https://github.com/OceanOptics/getOC It's a fantastic batch download tool.
process Level-1 images yourself using l2gen in NASA SeaDAS (see my other repository, Coastal-OC-Remote-Sensing for directions)
