AB: TES is one of four instruments on board the Aura spacecraft, launched on July 16, 2004. TES is an infrared Fourier transform spectrometer with a pointing system that allows staring at individual ground locations in the nadir view. The first spectra from TES were obtained in late August, and a special observation period in late September will focus on the south central Atlantic. Ozone mixing ratios in the upper troposphere are usually high at this time, because of transport of ozone formed from biomass burning in Africa. Ozonesondes will be launched several times a week from Ascension Island (8§S) during Aura overpasses in September, specifically for early validation studies of the TES nadir product. We will present the results of this validation, and discuss the capabilities of TES based on this work.
