We are currently measuring carbon dioxide, methane and carbon monoxide at the CUNY NGENS Observatory in Harlem during the COVID-19 shutdown. The change in the concentrations of all of these gases has been quite large. More work is needed to quantify how much is a reduction in emissions vs good weather conditions.
The Arctic is warming at twice the rate of the global average and soils are rapidly warming. Current projects: Scaling carbon fluxes across the YK Delta
For the past decade, observations of carbonyl sulfide (OCS or COS) have been investigated as a proxy for carbon uptake by plants. Current Project: Mercury in forests
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
