How to generate L3M product from L1B data source？

[lwk1542]

I downloaded MYD021KM and MYD03 data at a fixed location for one year. Then, I used the l2gen tool to obtain Rrs and chlor_a products. Now, I want to obtain annual average products with a resolution of 1 km，no related guidelines, however, to help me finish this (https://seadas.gsfc.nasa.gov/tutorials/video_tutorials/). Are there related documents about this processing？Thanks

Hi,

You can also find level 3 data at varying intervals (daily, monthly, annual, etc) here: https://oceancolor.gsfc.nasa.gov/l3/

l2bin creates a Level 3 bin file (L3b) from one or more Level 2 input files, and l3mapgen creates a Level 3 mapped image (L3m) from a Level 3 bin file.
