Nucaps Hyperspectral Infrared Atmospheric Sounding Product System: Products, Performance, and Algorithm Refinements for IASI-NG

Abstract

The NOAA Unique Combined Atmospheric Processing System (NUCAPS) is currently the National Oceanic and Atmospheric Administration (NOAA) operational hyper-spectral infrared sounding product system for deriving vertical profiles of temperature, water vapor, ozone, and trace gas products (CO, CH4, and CO2). In pursuance on the use of European Organisation for the Exploitation of Meteorological Satellite Second Generation (EUMETSAT-SG, expected launch in 2022) IASI Next Generation (IASI-NG) hyperspectral observations, NOAA Center for Satellite Applications and Research (STAR) has initiated refinements to the NUCAPS algorithm to produce NOAA unique products from the IASI-NG and accompanying Microwave Sounder (MWS). This paper presents an overview of the NUCAPS Suomi-NPP/NOAA-20 products performance and on-going efforts in setting up a NUCAPS-NG product development system using proxy/synthetic data sets provided by the EUMETSAT and generated at STAR for the IASI-NG instrument.
