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 (

Hi,
You can also find level 3 data at varying intervals (daily, monthly, annual, etc) here:

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.
