News & Announcements
This week, members of the Geddes group will be in San Francisco for the 2019 Fall Meeting of the American Geophysical Union.
Anthony is presenting a poster called "Potential of Constraining Ozone Dry Deposition Using Eddy Flux Measurements" on Tuesday (see the conference abstract here).
Jeff is co-convening sessions on Tuesday and Wednesday on Atmosphere-Biosphere Interactions and Atmospheric Chemistry, consisting of two oral sessions (here and here) and two poster sessions (here and here).
Follow the meeting on Twitter with the hashtag #AGU19.
Modeling the deposition of ground-level ozone to vegetation surfaces continues to be a painpoint in global models of atmospheric chemistry. We compared a variety of approaches, and discuss implications on interannual variability and long term trends. Read about this and more in Anthony's article that was just published in Atmospheric Chemistry & Physics.
Welcome to Arden Radford, who is joining the Geddes group as a Ph.D. student this fall. Arden earned a BA in Economics, and Astronomy, from Wellesley College, and is a recent alum of our MA in Remote Sensing & Geospatial Sciences at BU. In addition to research with the Geddes group, Arden is a participating student of the BU URBAN trainee program.
This week, Jeff is attending the Gordon Research Conference in Atmospheric Chemistry being held at the beautiful Grand Summit Hotel at Sunday River in Newry, Maine. He is presenting a poster called: "Biogenic ozone precursors in nonattainment regions of the US: Decreasing sensitivity to isoprene, increasing vulnerability to soil NOx".
The TEMPO Science Team converged on Madison, Wisconsin this week for the annual Science Team Meeting. TEMPO is a geostationary satellite instrument dedicated to monitoring tropospheric pollution over North America from space every hour of the day. For updates on the TEMPO instrument, check out the website here. We anticipate to hear an announcement of a host for TEMPO this summer, and at that point should have an idea of when to expect lift-off!
This year, Jeff was presenting his work on establishing an intra-urban network of ground-based remote sensing instruments in Boston for monitoring tropospheric trace gas column variability at the neighborhood-level. This work will help us link the latest satellite observations of atmospheric composition to air quality at the surface.
We congratulate Ph.D. Candidate Anthony Wong for successfully passing his qualifying exam. The qualifying exam consists of a week of written questions, followed by an afternoon-long oral exam. Well done, Anthony!
Last week was the 9th International GEOS-Chem Meeting at Harvard University. The meeting consists of rapid-fire presentations about model development and science, and break-out sessions to discuss priorities and future plans. The full program and webcast is available here.
Past IGC presentations: Check out Jeff’s presentation at the 2017 meeting discussing long-term deposition of reactive nitrogen oxides here, and his presentation at the 2015 meting about the development of a new land cover module here.
Research led by collaborators at the University of Virginia was recently highlighted in Science Magazine.
Jeff is a co-author on the original study, published in Environmental Science & Technology earlier this month, entitled "Observing Severe Drought Influences on Ozone Air Pollution in California". In this work, University of Virginia graduate student Angelique Demetillo and PI Sally Pusede describe their analysis that shows how the extended drought in California impacted surface ozone production by altering the natural emissions of biogenic hydrocarbons.
This weekend, Jeff spoke at the BU Astronomical Society's first annual weather balloon launch event. The afternoon consisted of talks from faculty and graduate students, as well as tours of the BU observatory, and scientific demonstrations, all organized by the BUAS students
This week, Jeff is in Geneva participating in the latest Global Atmospheric Watch Expert Meeting on Measurement-Model Fusion for Global Total Atmospheric Deposition (MMF-GTAD) at the World Meteorological Organization in Geneva. The title of his talk is: "Update and Future Directions of Satellite/Remote Sensing Activities Related to MMF-GTAD".
