Source File Organization

Files come in multiple time and spatial resolutions; for now our interest is in the files are that are:

• one file per day
• data are mapped onto lat/lon coordinates at 4km resolution
• a test set of daily files from April 2022 will be used to start
• note that some days in April are missing

Comments

Chlorophyll concentration from MODIS Aqua will be one of four parameters concatenated for use a input to a diatom biomass prediction algorithm.
