Brief Bio

Dr. Natalya Kramarova is a research scientist at the Atmospheric Chemistry and Dynamics Lab (code 614) in NASA Goddard Space Flight Center (GSFC). Dr. Kramarova’s primary field of research is related to remote sensing of atmospheric gases.

Dr. Kramarova received her MS degree in physics (2000) and later a Ph.D. Degree in Physics and Mathematics (2007) from Moscow State University, Russia. She worked on developing a radiative transfer algorithm and studying long-term ozone variability. In 2010-2017 Dr. Kramarova worked for Science Systems and Applications Inc. at NASA GSFC, characterizing ozone profile retrievals from NASA’s UV sensors (SBUV, OMPS). In January 2018 she joined NASA GSFC (code 614).

Dr. Kramarova is a member of the OMPS (Ozone Mapping and Profiler Suite), EPIC and SAGE III Science Teams. She is working on improvements for the ozone profile retrieval algorithm and on characterization of the retrieval errors.
