Faculty Profile

Mark Zondlo is associate professor of Civil and Environmental Engineering, and associate director of external partnerships in the Andlinger Center for Energy and the Environment, both at Princeton University. Zondlo’s research interests include atmospheric chemistry, cloud microphysics and chemistry, atmosphere-surface fluxes of nitrogen, water, and carbon, aerosol particle chemistry and dynamics, global air pollution, and laser sensor development.

The focus of Mark’s project is to identify how remote sensing measurements of ammonia (NH3) can be used to help improve air quality forecasts of PM2.5, a criteria pollutant that has proven difficult to reduce in urban regions. Ammonia is a critical trace gas precursor for PM2.5 in many areas, yet its measurements and emissions are poorly constrained. Recent advances in satellite measurements of ammonia offer new opportunities to constrain emission inventories and help to develop mitigation pathways for improved PM2.5 reduction. The specific research objectives of this project are the following:

  1. To validate absolute column NH3 amounts from IASI and CrIS with a suite of insitu/ ground-based measurements under a range of environments (pollution, thermal contrast, surface properties such as sand, water) and at the single pixel scale.
  2. To demonstrate how individual (i.e. not co-averaged in space/time) satellite NH3 measurements can be used to help improve air quality forecasts, particularly with respect to short-term (daily/weekly) spatiotemporal variations.
  3. To link NH3 measurements at the individual overpass “snapshot” times with the broader temporal patterns of emissions/concentrations throughout the day/night.
