Data Description

Aura OMI Level 2G Daily Global Products (Beta)
(for advanced users)

The Aura-OMI level 2G daily gridded data products are generated by the NASA OMI science team by binning the original pixels from the level 2 data products (15 orbits per day; 13x24 km spatial resolution at nadir) into 0.25 x 0.25 degree global grids. Descriptions on each level 2 algorithm are available here. All information from the original pixels, including time, latitude, longitude, view angles, data quality flags, etc., which fall within a grid cell are preserved.

Users can custom tailor their own level 3 product using the OMI level 2G Giovanni by applying their own data filtering criteria. The data filtering options include: Recommended Quality, Snow/Ice Flag, View Zenith Angle, Solar Zenith Angle, Reflectivity/Cloud Fraction, Path Length Index and Ocean Glint Width. See the table for default settings for each data filtering option based on data product. The user defined level 3 product can be binned at the original or coarser resolution.
