Urban Composition and Chemistry in NYC

We are currently measuring carbon dioxide, methane and carbon monoxide in Harlem and around the city as part of our research on urban composition and chemistry in New York City. We are also measuring carbon fluxes around the LDEO campus in Palisades, NY.

Carbon Dioxide and Methane in the Arctic

The Arctic is warming at twice the rate of the global average and soils are rapidly warming. Our research concentrates on carbon dioxide and methane fluxes in Arctic and Boreal ecosystems.

Carbon fluxes in mid-latitude Ecosystems

For the past decade, observations of carbonyl sulfide (OCS or COS) have been investigated as a proxy for carbon uptake by plants.

Remote Atmosphere Composition

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