TES/OMI Aura L2 Ozone Special Observation V003

TOL2O3S_3 is the Tropospheric Emission Spectrometer (TES)/Aura Level 2 (L2) Atmospheric Temperatures Limb Version 3 data product. It is derived from TES nadir and OMI (Ozone Monitoring Instrument) hyper-spectral measurements from the Aura satellite to jointly estimate an atmospheric ozone (O3) profile with extended vertical range compared to profiles retrieved from the individual measurement. TES and OMI stand-alone O3 profile retrievals are largely complementary, with TES IR measurements being largely sensitive to lower to middle troposphere while OMI total column O3 in the upper troposphere and lower stratosphere. TES nadir and OMI locations are paired within 6-8 min and within 220 km. The paired radiance measurements of the two instruments in each location are optimally combined to retrieve a single O3 profile along with other trace gases whose signal interferes with that from O3. This combined O3 profile has a vertical resolution and vertical range that is an improvement over the two stand-alone products, especially in the upper troposphere/lower stratosphere. This Aura TES-OMI O3 product using TES and OMI processing results will provide a unique data set for studying tropospheric transport of air pollutants and troposphere-stratospheric exchange processes.
