OMI/Aura Global Geometry-Dependent Surface LER 1-Orbit L2 Swath 13x24km V004 (OMGLER)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aura/omi/data2432
The OMI/Aura Global Geometry-Dependent Surface LER 1-Orbit L2 Swath 13x24km product, or OMGLER, provides GLER, and the computed top-of-atmosphere (TOA) radiance from which GLER is derived, for the OMI field of view.
Description
The OMGLER data also contain a number of ancillary/input parameters for each OMI pixel used to compute TOA radiance. The primary intended use of the product is to provide surface reflectance information for OMI cloud, aerosol and trace gas algorithms.
GLER is designed to easily replace commonly used LER climatologies within existing OMI algorithms. The product lead is Joanna J. Joiner (OMI US science team leader). The algorithm developer is Wenhan Qin.

The OMGLER product file is produced in the version 4 netCDF format. Each file contains GLER data for the daylit portion of an orbit (~53 minutes). There are approximately 14 orbits per day.
Files are roughly 15 MB in size.
