Paper on impact of detector heterogeneity on NWP forecasts published: A paper entitled “Investigating the Sensitivity of NCEP's GFS to Potential Detector Heterogeneity of Hyperspectral Infrared Sounders” authored by Agnes Lim (Cooperative Institute for Meteorological Satellite Studies, CIMSS), Sharon Nebuda (CIMSS), James Jung (CIMSS) and Joe Predina (Logistikos Engineering) had been published in Earth and Space Science (https://doi.org/10.1029/2021EA001891). Field-of-view (FOV) heterogeneity on numerical weather prediction (NWP) analyses and forecasts was assessed in a pseudo-observing system simulation experiment (OSSE) framework to understand its impact. Results showed infrared hyperspectral detector heterogeneity influences selection of clear profiles as the National Center for Environmental Prediction's (NCEP) current thinning algorithm prefers warmer pixels. Bias correction schemes poorly characterize biases introduced by detector heterogeneity. Unremoved biases are assimilated as “information” resulting in a biased analyses and degraded forecasts. (A. Lim, CIMSS, 608-263-6720)

Manuscript accepted to Public Discussion Forum at ACPD: A manuscript titled "The Mount Everest Plume in Winter", authored by Edward Hindman from the City College of New York and Scott Lindstrom from the Cooperative Institute for Meteorological Satellite Studies (CIMSS), has been accepted for preprint posting and interactive peer review at Atmospheric Chemistry and Physics Discussions (ACPD), part of Atmospheric Chemistry and Physics (ACP) of Copernicus Publishing. The article includes visible imagery from Himawari-8 (processed with geo2grid, a software package developed at CIMSS) that show snow plumes downwind of Mt. Everest. (S. Lindstrom, CIMSS, 608 263 4425)

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 Bachmeier and Tim Schmit published these case studies: "Blowing snow across parts of Minnesota and Iowa" (Jan. 6), "Winter storm affecting the Mid-Atlantic states" (Jan. 3), "There GOES 2021" (Jan. 1), "Marshall Fire near Boulder, Colorado" (Dec. 30).
