Róisín Commane

Principal Investigator

My research focuses on the surface - atmospheric exchange that affects atmospheric composition.

I'm at atmospheric chemist interested in longer-lived trace gases and the processes that drive how much of these gases we see in the atmosphere. I'm interested in ecosystem interactions with the atmosphere in Arctic, mid-latitude and urban environments. Recently I've been leading the development of a measurement network for CO2 and methane around New York City. 

Before that I spent time measuring CO2, CH4, N2CO in the remote atmosphere on the NASA DC-8 aircraft as part of the ATom project. I also work on understanding carbon dioxide and methane in the Arctic as part of the NASA CARVE and ABoVE projects. Our recent CARVE journal articles include Commane et al., PNAS, 2017. Prior to that, I developed a laser spectrometer instrument to measure fluxes of carbonyl sulfide (OCS) and deployed this instrument at Harvard Forest, MA. I worked to understand the processes controlling the OCS flux through collaboration with colleagues in the ecological sciences. Related OCS publications include Commane et al, PNAS, 2015.
