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 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 the on-going efforts in setting up a NUCAPS-NG EDR product development system using proxy/synthetics data sets provided by the EUMETSAT and generated at STAR for the IASI-NG and MWS instruments. In addition to augmenting the NUCAPS system using the IASI-NG proxy/synthetic data sets (0.125 cm-1, 16,921 channels, 4 x 4 field of views, FOVs), the high spectral resolution Fourier Transform Spectrometer data are transformed into various sensor/instrument configurations, such as (a) CrIS (0.625 cm-1, 2211 channels, 3 x 3 FOVs) and (b) current IASI (0.625 cm-1, 8461 channels with 2 x2 FOVs). Similarly, the MWS data are transformed into ATMS/AMSU-A/MHS field of regards (FOR) following sensor geometry/collocation criteria between hyperspectral IR sounders and the microwave instruments. NUCAPS EDR products generated for these instrument configurations are evaluated for relative performance assessment from these instrument configurations. This paper presents preliminary results on information content with different sets of spectral channels, cloud-clearing improvements realizable with different FOV configurations within the FOR retrievals, and assessment of both the NUCAPS first guess and the final physical retrieval products with the available instrument characteristics. The augmentation of the current NUCAPS system for the IASI-NG, along with the analysis tools adapted for IASI-NG, will help to alleviate any issues in the implementation and provide realistic results when applied to improved proxy data sets expected in the future for pre-launch characterization of the NUCAPS IASI-NG EDR products.
