AB: Geophysical parameters derived from AIRS/AMSU-A observations are important for both improving numerical weather prediction and studying climate variability and trends. For the latter purpose, interannual differences of AIRS monthly mean products should be consistent with those of analogous geophysical parameters derived from other sources, where they are accurate, and add new information where they are less accurate. AIRS/AMSU-A data has been analyzed for the months of January 2003 and January 2004. Monthly mean temperature and water vapor fields of retrieved parameters have been generated and compared to comparable fields obtained from collocated ECMFW 6-hour forecasts to determine the degree that AIRS inter-annual difference fields are consistent with expectations at locations and pressure levels where ECMWF forecasts should be accurate, and add information where ECMWF forecasts are questionable. AIRS inter-annual differences are also compared with inter-annual differences of TOVS Pathfinder Path-A products, CERES OLR, and Spencer and Christy MSU2R and MSU4 products to assess compatibility with long term satellite data sets.
