International ATOVS Processing Package
Entry ID: IAPP

[ Get Service ]

Summary
Abstract: The International ATOVS Processing Package (IAPP) has been developed to retrieve atmospheric temperature and moisture profiles, total ozone and other parameters in both clear and cloudy atmospheres from ATOVS radiance measurements. The IAPP algorithm, which operates on NOAA-15 and later data, retrieves the parameters in 4 steps: 1) cloud detection; 2) bias adjustment; 3) regression retrieval; and 4) nonlinear iterative physical retrieval. A publication by Li, Wolf, Menzel, Zhang, Huang and Achtor, Journal of Applied Meteorology (August 2000) provides details on the algorithm.
