The University of Wisconsin-Madison SSEC is pleased to announce the release of the NOAA Unique Combined Atmospheric Processing System (NUCAPS) for IASI Version 1.0 software for retrieval of atmospheric profiles of temperature, moisture and trace gasses as well as cloud-cleared radiances from input satellite data. This version supports retrievals from the Infrared Atmospheric Sounding Interferometer (IASI), the Advanced Microwave Sounding Unit-A (AMSU-A), and the Microwave Humidity Sounder (MHS) that fly on board the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) Metop-A and Metop-B satellites. It is being released as part of the Community Satellite Processing Package (CSPP).
NUCAPS development is led by Walter Wolf and Lihang Zhou at the NOAA NESDIS Center for Satellite Applications and Research (STAR). This CSPP release was created in close collaboration with Chris Barnet (the NOAA government science lead for NUCAPS from 2003 to 2013) and his staff of developers of the NUCAPS science code, Antonia Gambacorta and Nadia Smith.
This CSPP release provides NUCAPS IASI Version 1.0, adapted and tested for operation in a real-time Direct Broadcast (DB) environment. The software contains binary executable files and supporting static data files, as well as input and output files for verification of a successful installation. Source code for the NUCAPS IASI package is not included in this release. CSPP NUCAPS for IASI uses Level 1 inputs generated from the ATOVS and AVHRR Pre-processing Package (AAPP) supported by the EUMETSAT NWP Satellite Application Facility (SAF).
