OMI/Aura Surface UVB Irradiance and Erythemal Dose Daily L2 Global Gridded 0.25 degree x 0.25 degree V3 (OMUVBG)

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aura/omi/data2028

This is Level-2G daily global gridded Aura-OMI Spectral Surface UVB Irradiance and Erythemal Dose product (OMUVBG).

Description

The OMUVBG is a special Level-2 Global Gridded type data Product (referred as Level 2G or L2G) where Level-2 or swath pixel data are binned (but not averaged)into 0.25x0.25 degree global grids. It contains the data for all L2 scenes that have observation time between UTC times of 00:00:00 and 23:59:59.9999.

All ancillary parameters such as latitude, longitude, time, solar and viewing angles are also saved for each pixel. First two dimensions of each parameter correspond to spatial (Lat/Lon based) Grid ID and third dimension identifies the pixel or observed scene (referred as 'candidates' ID). Scientists can apply a data filtering scheme of their choice, average good quality pixels data in each grid and create their Level-3 products.

The OMUVBG files are available in the version 5 EOS Hierarchical Data Format (HDF-EOS5). Each file contains daily data from the day lit portion of the globe. The maximum file size for the OMUVBG data product is about 128 MBytes.
