Eight Day Product (08_E3) File Format Basics
Eight-Day
The Eight-Day Global Joint Product contains roughly 800 statistical datasets derived from Level-2 MODIS Atmosphere parameters that are summarized over an 8-day period. The ESDT names areMOD08_E3 (Terra) and MYD08_E3 (Aqua).

Algorithm Overview
L3 Multiday (8-Day & Monthly) Algorithm
There are a number of general L3 Multiday algorithm characteristics:
a) Only the L3 Daily files are used as input. (Greatly improves algorithm efficiency.)
b) L3 Daily and Multiday HDF files use an identical grid, SDS dimensions, and histogram bin definitions. (This is an algorithm requirement.)
c) There is no “valid range” check, only “Fill_Value” grid cells are universally excluded.
