Urban Composition

Our observations in New York City include measurements of carbon dioxide, methane and carbon monoxide from a tall building, ground-based mobile platforms and small aircraft. We also measure species that are co-emitted with methane from different sources, ethane and nitrous oxide, at the CUNY NGENS Observatory.

Remote Atmosphere

Our understanding of the atmospheric composition of the most remote regions of the world has been limited by a lack of observations - until now. Current Project: NASA ATom Project
