Atmospheric Correction

Another post about my adventures with MODIS data

MODIS aqua appear to have at least 3 post atmospheric correction product

LW_nnn : The water-leaving radiance.

nLw_nnn : Normalised water leaving radiance

Rrs_nn remote sensing refectance

A200xxxxxxxxxxx.L2_LAC_OC

includes these Remote sensing reflectances

Rrs 412 --> Band 8

Rrs 443 --> Band 9

Rrs 469 ---> Band 3

Rrs 488  --> Band 10

Rrs 531 --> Band 11

Rrs 547 --> Band 12

Rrs 555 --> Band4, Band 12

Rrs 645 --> Band 1

Rrs 667 --> Band 13

Rrs 678  --> Band 14

Rrs_nnn = nLw_nn/ F0_nnn;

F0_nnn = extraterrestrial solar irradiance (constant provided in metadata )

Think I need a greater understanding of data available and the processing so I can make reasonable choices.
