Tropospheric Data from the United States

There are several tropospheric data fields available from the U.S. Tropospheric constituent species are limited primarily to ozone and water vapour abundance. Global satellite fields such as cloud optical thickness/fraction, aerosols, surface UV, etc., are important for the analysis of the troposphere which includes climate change applications and the effects on the photochemistry of constituents in models. The first section gives a summary of the data fields most used, together with some current developments at NASA in deriving tropospheric ozone profiles. The upcoming EOS Aura tropospheric constituent measurements are then discussed.
