AB: AIRS and MODIS data the the Upper Troposphere and Lower Stratosphere (UT/LS) are validated and used to understand the covariation of clouds and humidity in this critical and sparsely observed region of the atmosphere. AIRS and MODIS data are validated against in-situ aircraft data of trace gases and clouds from the NASA WB57 aircraft in January and February 2004. Satellite observations compare well to aircraft data; temperature is generally within $\pm$1.5K and water vapor is within $\pm$25% of aircraft observations for pressures above 150 hPa and mixing ratios above 10ppmv. Thicker cirrus clouds are well resolved from the satellite. 2 years of data from AIRS and MODIS are used to illustrate the climatology of Temperature, Ozone & Water Vapor in the UT/LS. As an example of the potential of this data, the data is used to demonstrate the covariation of clouds from MOIDS and humidity from AIRS.
