Algorithm Theoretical Basis Documents

All scientific parameters contained within the Level-3 Monthly Global Joint Atmosphere product (MOD08_M3), are derived from Level-2 (MOD04_L2, MOD05_L2, MOD06_L2, and MOD07_L2) products. Search the MOD08_M3 parameter list, below, to locate the correct Algorithm Theoretical Basis Document (ATBD) for that product.
