Figure: Total transmittance from surface to satellite (black line). The red line is the accumulated CRTM radiance Jacobian to ozone profile. Symbol “c” is the position at 331 nm used to estimate surface reflectance. The symbol “o” are the two channels, that we propose, to estimate the surface reflectance. The surface reflectance for other channels is either interpolated or extrapolated from the two reflectance at 347.6 nm and 371.8 nm.

UV Surface Reflectance from OMPS Nadir Mapper (NM) Radiance—Simulation and Assimilation

ESSIC/CISESS scientists Christopher Grassotti and Xingming Liang are co-authors in a recently published study that documents the first ultraviolet radiance assimilation for atmospheric ozone in the troposphere and stratosphere. The paper, titled “Experimental OMPS Radiance Assimilation through One-Dimensional Variational Analysis for Total Column Ozone in the Atmosphere”, was published in Remote Sensing and includes co-authors from the NOAA/NESDIS Center for Satellite Applications and Research.

Moradi to Assimilate Measurements from Active Spaceborne Radars

ESSIC/CISESS Associate Research Scientist Isaac Moradi is the PI of a proposal selected by NASA ROSES to assimilate measurements from active spaceborne radars into NASA GEOS model. The project will benefit from CloudSat CPR and GPM DPR observations and will be conducted in collaboration with Co-Is from NASA Global Modeling and Assimilation Office and the Mesoscale Atmospheric Processes Laboratory.

ESSIC Recognizes Distinguished Faculty and Staff

As a now traditional part of the ESSIC end-of-year Holiday Party, two annual peer awards were presented to honor the year’s Best Paper and the Employee of the Year. This year, Director Ellen Williams presented these awards to Toshi Matsui, Associate Research Scientist, as well as Donna Gray, Coordinator, and Luther Clark, IT Coordinator.

Moradi Convenes and Chairs Three AGU Sessions

ESSIC/CISESS Associate Research Scientist Isaac Moradi is convening and chairing three sessions at the American Geophysical Union Fall meeting, occurring virtually this year due to COVID-19. The sessions are “Data Assimilation, Reanalysis, and Observing System Simulation Experiments I”, “Data Assimilation, Reanalysis, and Observing System Simulation Experiments II Posters”, and “Calibration and Validation of Satellite Earth Observation Systems I Posters”.
