WMO Expert Meeting on Global Total Atmospheric Deposition
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".
Colloquium at the University of Washington
This week, Jeff is visiting the University of Washington to speak at their Department of Atmospheric Science colloquium about our group's research. The title of his talk is: "Checking Atmospheric Chemistry's Pulse: Modeling and Remote Sensing of Biosphere Interactions".
Geddes Group @ AGU
This week, two members of the Geddes group will be attending the Fall Meeting of the American Geophysical Union in Washington, DC.
Anthony will be presenting a poster called "Long-term Global Multi-physical Modelling of Ozone Dry Deposition Velocity - with Focus on Process Uncertainty and Implication on Air Quality Modelling" (see the abstract here).
Jeff will be presenting a talk called "Characterizing sea breeze effects on surface ozone concentrations in the Boston region, and implications for remote sensing of local air quality" (see the abstract here).

Chemistry Seminar at BU
Today, Jeff will be giving the Department of Chemistry PChem Seminar in LSE 103 at 2pm. The title of his seminar is: "Keeping and Eye on the Atmosphere: Modeling and Remote Sensing of Atmospheric Chemistry". https://www.bu.edu/chemistry/seminars/p-chemseminars/
Article Published in Atmospheric Measurement Techniques
Nitrogen dioxide (NO2) is found in the troposphere (the layer of the atmosphere closest to the surface) and in the stratosphere (the layer of the atmosphere that protects us from harmful UV radiation). When we measure NO2 from space-based instruments, we measure the combined NO2 in both layers. Separating the stratospheric and tropospheric content is critical to the application and interpretation of these satellite observations. In our latest article that has just been published in Atmospheric Measurement Techniques, we show how this will be possible for a new geostationary satellite instrument called TEMP (anticipated to launch sometime around 2021).

Research on Tap: Understanding and Forecasting Change in Our Natural World
This afternoon, Jeff is participating in a "Research on Tap" event at BU, focused on gathering together investigators across many disciplines who are interested in exploring how to forecast changes in the natural world. Jeff will be discussing links between variability in the natural environment and global air quality. The event was hosted by Gloria Waters (Vice President and Associate Provost for Research at BU) and Prof. Mike Dietze (Associate Professor in the Department of Earth & Environment at BU).
GEMS Meeting in Seoul
This week, Jeff is in Seoul, Korea, to attend the 9th Geostationary Environmental Monitoring Spectrometer (GEMS) Science Team Meeting. GEMS is a geostationary satellite instrument that will be dedicated to monitoring tropospheric pollution over Asia. Jeff will be presenting his work on an algorithm to separate the signal of NO2 in the stratosphere from the total atmospheric column, in order to determine the amount of NO2 in the troposphere alone.
Welcome to Marissa
Welcome to Marissa Lee, who is joining the Geddes group as a work-study student this year. Marissa is an undergraduate student at Boston University, majoring in Earth and Environmental Science with a minor is Remote Sensing and GIS.
Is the U.S. the cleanest country on the planet?
Last week, Jeff was quoted in an article from politifact.com discussing the truth in a statement from President Trump about how clean the air and water is in the United States. Thanks to Manuela Tobias for reporting.
Welcome to Taylor
Welcome to Taylor Adams, who is joining the Geddes group as a Ph.D. student this fall. Taylor earned a BA in Chemical and Biomolecular Engineering from the University of Tennessee Knoxville. In addition to research with the Geddes group, Taylor will be in the inaugural cohort of the BU URBAN trainee program.
