Postdoc: Satellite-based urban CO2 and air pollutant emissions

JPL/NASA • Pasadena, CA

7d • Onsite

About The Position

The postdoctoral researcher will investigate urban fossil fuel CO₂ and air pollutant emissions using satellite observations, emission inventories, and data assimilation. The research will characterize spatial and temporal emission patterns across major cities worldwide, from city to sub-city scales, and examine relationships with urban development, emission sources, and mitigation strategies.

The researcher will combine satellite-based CO₂ emission estimates from OCO-2/3 with air pollutant emission estimates informed by observations from TEMPO, GEMS, and TROPOMI, leveraging JPL’s MOMO-Chem and CMS-Flux systems. The work includes analyzing urban emission distributions and trends, comparing satellite-based estimates with multiple emission inventories, and applying the modified environmental Kuznets curve (MEKC) framework to examine emission changes in relation to economic development and mitigation efforts.

The research will advance understanding of urban emission processes, inform improvements to emission inventories, and support assessment of climate and air quality mitigation strategies. The researcher is expected to develop reproducible analysis methods, collaborate with interdisciplinary research teams, and publish findings in peer-reviewed scientific journals. The appointee will conduct research in collaboration with the JPL advisor, resulting in publications in the open literature. The postdoctoral position is awarded for a minimum one-year period and may be renewed for up to three years.
