Home

Recent OMI data (from Jan 24, 2009) should be used with caution (read more).

This is the experimental BETA interface for visualization and analysis of the Aura OMI version 3 daily global level 2G data products. Available products include OMAEROG, OMAERUVG, OMDOAO3G, OMTO3G, OMSO2G, and OMHCHOG. The OMI L2G data are binned to 0.25°x0.25° grids, except for OMSO2G which are binned to 0.125°x0.125° grids. Before using it in L2G Giovanni, L2G data are filtered by good quality as defined by the science teams.

The OMI Level 3 daily gridded data are also available from Giovanni.

OMI Aerosol Wavelength

Select a wavelength value from the pulldown list. This option is only enabled if a parameter from the OMAEROG or OMAERUVG product is selected! Otherwise, this option is greyed-out and not available.

Wavelength

NOTE: Selected 3D parameters must have the same 3rd dimension (e.g., pressure, altitude, wavelength, etc.) units in order to enable the vertical level menu.
