Hi! I'm Omar! —
I am an air quality scientist engaged in interdisciplinary research at the intersection of climate change, air pollution , health, equity, and policy.
I explore how changes to human emission patterns could affect health and equity, how climate and air pollution interact, how remote sensing can be integrated with modeling, and how the sources that contribute to pollution vary across different geographies.
Outside of the research projects I have been involved in and the scientific papers I have published, I am interested in sharing the data I generate and in documenting and recording the different methods and techniques I use in tutorials!
Featured figures —
Below is a one-year simulation of surface-level PM2.5 concentrations simulated in a new nested South America domain (in prep) for the chemical transport model GEOS-Chem classic.
Accompanying this forward model simulation is an adjoint calculation of sensitivities of PM2.5 in the city of Santiago, Chile to emissions of its chemical precursors. In the below figure we calculate sensitivities to ammonia.
