Research

Urban Composition & Chemistry: New York City

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. 

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. Current Project: NASA ATom Project

Invited presentation at AMS Annual Meeting 2021

Róisín gave an invited talk at the American Meteorological Society Annual Meeting which was held online instead of New Orleans in January 2021. Her talk was focussed on "Characterizing air masses in the remote atmosphere using in situ airborne observations: Nitrous Oxide - N2O" and highlights the nitrous oxide observations from the NASA ATom missions. A paper by Yenny Gonzalez Ramos will be submitted soon. 

Big shout out to all the NASA ATom Science Team for making this possible.
