SSEC and CIMSS Scientists in the News: Scientists at the University of Wisconsin-Madison (UW) Space Science and Engineering Center (SSEC) and the Cooperative Institute for Meteorological Satellite Studies (CIMSS) provide expert interviews, imagery and case studies to promote science. This week: 1) CIMSS Satellite Blog contributors Scott Lindstrom, Margaret Mooney and Scott Bachmeier published these case studies: "SAR data over Tropical Cyclone Freddy in the Indian Ocean" (Feb. 9), "Tropical Cyclone Gabrielle in the Coral Sea" (Feb. 8), "Clear skies over the western Great Lakes" (Feb. 8), "Rapidly intensifying midlatitude cyclone off the US East Coast" (Feb. 6), "SAR Observations near American Samoa (part III)" (Feb. 6), "Differences in ice reflectivity over Hudson Bay" (Feb. 6), "Sentinel 1A SAR data over the South Pacific" (Feb. 5), "Wildfires in Chile" (Feb. 4), "Great Lakes Ice Extent" (Feb. 4), "Train derailment and fire in Ohio" (Feb. 3) and "Ice storm across the Southern Plains and Mid-South" (Feb. 3).

PUBLICATIONS:

Paper published on inter-calibration of GEO sounder and imager: A manuscript titled "Inter-Calibration of Geostationary Imager Infrared Bands Using a Hyperspectral Sounder on the Same Platform" has been published in Geophysical Research Letters (https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2022GL101628. This study shows that the imager and hyperspectral IR sounder on the same platform have the unique advantages: the inter-calibration can be conducted for all viewing angles and at all times. The inter-comparison of GIIRS and AGRI under homogeneous scenes shows that the differences are scene temperature dependent, less dependent on cloudiness and local zenith angle, and exhibit significant diurnal variations. (Z. Li, CIMSS, 608-890-1982)

CrIS polarization correction paper published: The following paper by Taylor et al. was published on 26 January 2023: Taylor, Joe K., Henry E. Revercomb, David C. Tobin, Robert O. Knuteson, Michelle L. Loveless, Rebecca Malloy, Lawrence Suwinski, Flavio Iturbide-Sanchez, Yong Chen, Glen White, Joe Predina, and David G. Johnson, 2023,  "Assessment and Correction of View Angle Dependent Radiometric Modulation due to Polarization for the Cross-Track Infrared Sounder (CrIS)", Remote Sensing, 15(3), 718. https://doi.org/10.3390/rs15030718. The paper presents a model for the polarization-induced calibration bias and the associated correction for the CrIS instrument, along with details of the model parameter determination, and the impact of the correction on the calibrated radiances for a range of scene temperatures and types.
