Characterization of Atmospheric Aerosol in the US Southeast from Ground and Space-Based Measurements, and GEOS-Chem Model

About the role

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Responsibilities

To unravel the complex nature of aerosol effects on the surface temperature in the SEUS region we will investigate how SEUS aerosol with observationally constrained optical properties and vertical distributions impact surface temperatures. We will analyze in-situ, aircraft, and satellite data from the Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) 2013 field campaign in conjunction with GEOS-Chem transport model in order to:

• Quantify vertically resolved microphysical (size distribution) and optical properties (refractive index, SSA) of summertime aerosols in aerosol-dominated regions of the SEUS;
• Generate a multi-year record of region-specific aerosol products, and establish a relation to decadal temperature trends;
• This work will allow us to evaluate the impact of aerosol in the SEUS, and establish whether aerosols are the primary driver of temperature trends in the region.
