Description: >
This document specifies the product format for the OMDOAO3 Level 2 PGE,
which uses the DOAS method to determine total column ozone from OMI
UV-2 measurements (Reference 1). The product is stored as one HDF-EOS 5
swath file for each granule (i.e., one orbit) of OMI Level 1B data, and
has a size range of 1 to 20 Mb.
