Paper Abstract

This work describes an iterative algorithm capable of determining the atmospheric parameters (temperature and water vapour profiles) by using NOAA ATOVS data and “in situ” observations currently collected at the Broglio Space Centre (BSC, located in Malindi-Kenya, 40 E, 3 S) of the Centro di Ricerca Progetto San Marco (CRPSM) of the University of Rome “La Sapienza” (Italy). The method is based on the usual approach to the problem of retrieving atmospheric characteristics: 1. a forward model (using the Modtran atmospheric code); 2. a numerical method for solving systems of non-linear equations (by means of a Broyden’s Quasi-Newton methods and a regularization method coupled with a preconditioning to computing stabilized solutions to the ill-posed problems). The retrieval method for the temperature and water vapour is discussed in detail; comparisons are also made with available co-located atmospheric information from balloon-based soundings. The aim of this paper is to evaluate the accuracy of the estimate of the tropical atmosphere parameters using a retrieval algorithm developed by authors, based on Broyden’s method for systems of non-linear equations.
