Data-constrained Air Quality Modeling

About the NASA Postdoctoral Program

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 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.

CTM and AQ models are vital tools used to understand tropospheric chemical composition, air quality, and human health. Projects will use CTMs and AQ models combined with in situ and remote‑sensing data to better understand and forecast tropospheric chemistry and air quality from regional to global scales. Demonstration of how in‑situ and remote‑sensing data can improve the ability of CTMs and AQ models to replicate and forecast tropospheric composition is required.

Application of data‑assimilation techniques in CTMs and AQ models is encouraged. A wide variety of CTMs (e.g., WRF‑Chem, GEOS‑Chem) and AQ models (e.g., CMAQ) can be used. Near‑real‑time data from NASA satellites (e.g., OMI, TROPOMI, TEMPO) and ground‑based networks (e.g., TOLNet, Pandora) will be prioritized. The recently launched TEMPO sensor is especially encouraged.

• PhD in an Earth Science related field.
• Experience with running and developing 3‑D atmospheric CTMs and data assimilation techniques.
• Strong analytical skills and computer programming ability.
• Strong written and verbal communication skills.
