This federal contract award, number NNX15AJ51A, is a grant for research provided by the National Aeronautics and Space Administration (NASA) to Duke University for a project aimed at improving atmospheric composition-climate modeling capabilities at the NASA Goddard Institute for Space Studies (GISS). The $572,884.23 grant will fund a collaboration between the Shindell Research Group at Duke University and NASA GISS, bringing together expertise in atmospheric chemistry, aerosols, and climate modeling. The project focuses on (1) coordinating composition modeling to keep pace with developments in GISS's climate model, and (2) applying the composition-climate model to better understand the climate system's response to inhomogeneously distributed ozone and aerosol forcing. This contract award does not have a set-aside designation.

We propose to restore a longstanding collaboration between the shindell research group, now located at duke university, and NASA giss on atmospheric compositionclimate interactions. The project brings together the expertise of the shindell group in atmospheric chemistry and aerosols with that of giss in coupled climate modeling, and builds on the historical partnership in the analysis of the climate response to various forcing agents (including inhomogeneous ones) by members of both teams (e.g. shindell, schmidt, miller). The research is directed at (1)coordinating composition modeling to improve the current capabilities at giss and maintain those as the rest of the climate model continues to develop, for example in the higher resolution cubed-sphere versions, and (2) applying the compositionclimate model to better understand the response of the climate system to the inhomogeneously distributed ozone and aerosol forcing and to understand the role these play in the simulation of hemispheric and regional scale historical climate changes.
