NASA 2017 Summer Intern

NASA - Global Modeling and Assimilation Office (GMAO)

June 2017 - August 2017

Advisor- Anton Darminov

Performed experiments with the GEOS GOCART aerosol model testing how changes to particle initial size distribution and gravity settling (dry removal) effective size globally alter dust column mass and AOD. Results were shown at the 2017 summer intern research poster session.

Assimilation of AVHRR Data in a Reanalysis Context

Conference: AGU Fall 2020 Meeting (Virtual)

Abstract : 

The Advanced Very High-Resolution Radiometer (AVHRR) is a broad-band, four or five channel scanner, sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum. Data records from AVHRR instruments on-board Polar Orbiting Satellites span 30 years. The AVHRR radiance from the Infra-red channels have been directly assimilated over the ocean in NASA GEOS system since 2012 and have made a positive contribution towards the skin temperature analysis. Given the positive impact of the assimilation of AVHRR radiance it is necessary to exploit the data for reanalysis related application. The AVHRR data is currently being re-processed at GMAO NASA for historical periods and assimilated in the planned upcoming reanalysis framework. In this poster a description of the re-processing of AVHRR data is provided and a case study from 2004 based on Hurricane Katrina is presented.
