Advancing geostationary infrared sounding, and its application. By: 1 Gary S. Wade, with input from 1 Timothy J. Schmit, 2 James P. Nelson III, 2 Jun Li, 2 Zhenglong Li, and 1 Robert M. Aune, among others 1 NOAA/NESDIS/St. AR/Co. RP/Advanced 2 Space Satellite Products Branch (ASPB) and Science and Engineering Center (SSEC), all within the Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin-Madison Presented during visit to the National Weather Service (NWS) Storm Prediction Center (SPC) in Norman, OK on 29 May 2009 2

An Improved GOES Sounder Retrieval Algorithm 24 Apr 2007 Improvements were made to the Ma et al. (1999)-based version of the GOES physical retrieval algorithm by employing: (1) a regression-retrieved temperature and moisture firstguess (versus a forecast), (2) a real covariance matrix for the first-guess (versus a correlation coefficient matrix), (3) a new radiance bias adjustment scheme along with inverted cone filtering, and (4) the “PFAAST” transmittance model (for calculated radiances). Better stability evolution An improved retrieval algorithm has been demonstrated in: Li, Z. , J. Li, W. P. Menzel, T. J. Schmit, J. P Nelson III, J. Daniels, and S. A. Ackerman (2008), GOES Sounding improvement and applications to severe storm nowcasting, Geophys. Res. Lett. , 35, L 03806, doi 10. 1029/2007 GL 032797. 3
