Róisín gave an invited seminar in the Dept of Physics at University of Toronto, with a quick side trip to visit colleagues at Environment and Climate Change Canada. Thanks to host Debra Wunch!
Roisin attended the NASA ATom Science Team meeting in Boulder, CO and presented the group’s work on African air quality.
Roisin attended the CO2-USA (CO2 Urban Synthesis and Analysis Network) workshop in beautiful Salt Lake CIty to learn about carbon fluxes from various urban areas in the US.
Roisin also participated in the Arctic Data Center's Permafrost carbon synthesis working group in Santa Barbara, CA (website). With researchers from Germany, Japan, Korea, US, Canada and Finland, we had a great overview of pan-Arctic flux sites and much progress was made!
Emily has joined the group as a G1 gradutate student in DEES. Welcome Emily!
Maggie is continuing her summer research on Arctic methane into her Senior Research Thesis at Harvard College.
Bronte is continuing in the group as a research assistant at Lamont for the fall semester, with a continuing focus on developing an urban carbon measurement network.
Luke is continuing as a long-distance postdoc with regular trips to NY from Boston.
Roisin spent the start of the semester traveling and presenting the group's work. She presented our Arctic carbon…

During the recent extreme temperature and air quality episode, Róisín was out at Brookhaven airport to help John Mak, from Stony Brook University, with flight prep. John was measuring ozone and NOx and also flew our Picarro CRDS instrument that measures CO2, CH4 and CO. John completed two successful flights each of Saturday and Sunday and analysis of the data is ongoing.
Over all it was a successful, if (heat) exhausting weekend!
Ludda Ludwig has been awarded a Future Investigator in NASA Earth and Space Science and Technology (FINESST) fellowship for her work on Hierarchical Scaling of Carbon Fluxes from Terrestrial-Aquatic Interfaces in the Arctic. Congratulations Ludda! We're excited to have Ludda begin her graduate work in September.

Róisín Commane, Emily Follansbee, Chandler Morris, and Charlotte Kwong travelled to Petersham, MA to visit the Harvard Forest research facility in June 2019. Our aim was to make qualitative observations pertaining to studies of trace gas fluxes of CH4, OCS, and O3, to change the setup and gather data from OCS sensors for observing patterns in stomatal conductance.

Congratulations to Margaret Powell for winning the Hoopes Prize for her senior thesis at Harvard College: "Four Years of Alaskan Methane Emissions from the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) Aircraft Campaign". She was nominated by her primary supervisor Prof. Steve Wofsy.
Roisin and Emily visited John Mak's group at Stony Brook University on Long Island on April 30. John gave us a tour of his lab before we visited the New York State Dept of Environmental Conservation air quality measurement site at Flax Pond (you can find the online data here!), which is just to the north of Stony Brook University.
John will be flying around New York City and out over the Long Island sound as part of the New York State Energy Research and Development Authority (NYSERDA) funded and Northeast States for Coordinated Air Use Management (NESCAUM) coordinated …
We're delighted to announce that we were recently funded by New York State Energy Research and Development Agency (NYSERDA) to work on a project lead by Lee Murray, University of Rochester (PI) and Eric M. Leibensperger, SUNY Plattsburgh. We will make continuous measurements of methane at air-quality monitoring sites in New York State. This project aims to constrain regional upwind emissions of methane arriving into New York from neighboring states (hello Pennsylvania and New Jersey :) and examine the downwind impacts of those emissions on…
Maggie Powell joined us at Lamont to lead group meeting this week. She presented her impressive senior thesis work at Harvard College, which focuses on Arctic methane from the NASA CARVE aircraft program. Maggie will be working on a manuscript based on this work over the summer before she leaves for a masters program in Germany in September.
Our NSF funded project to look at how mercury from the atmosphere ends up in forest soils got some media coverage!

The project is a collaboration with Prof. Daniel Obrist at UMass Lowell and there is a Postdoctoral Research position available in Daniel's group.
Project Overview and Details
Roisin made her first trip to Albany, NY for the New York State Energy Research and Development Authority (NYSERDA) Energy-Related Air Quality and Health Effects Research Workshop. It was great to hear about all the wonderful monitoring and research going on in New York State and City!

The final day of the meeting was the Long Island Sound Tropospheric Ozone Study (LISTOS) science team meeting, with a discussion of…
Ludda will be joining the Department of Earth and Environmental Science PhD program in the fall of 2019. Her interests are scaling methane and carbon dioxide emissions, climate change impacts on Arctic carbon cycling through wildfires and permafrost thaw, and coupled biogeochemical cycling at terrestrial-aquatic interfaces. Ludda received her M.Sc. in Biological Sciences from the University of Alaska Fairbanks and B.A. in Biology, Chemistry, Mathematics, and Environmental Studies from St. Olaf College
