Harvard Atmospheric Chemistry Seminar
This week, Jeff was invited to give the Atmospheric & Environment Chemistry Seminar at Harvard University. His talk is called "Clear Skies Ahead? New Challenges and Opportunities in Remote Sensing of Urban Air Quality".
Check out the abstract for the seminar here.
American Meteorological Society Meeting
This week, two members of our group attended the American Meteorological Society Meeting in Baltimore.
Graduate student Rachel Mooers attended the AMS as a student volunteer. Thanks for your dedication, Rachel!
Graduate student Arden Radford presented a poster on our NOAA-funded CO2-AQ-USA project. The title of Arden's poster is: "Local to Regional Heterogeneity in Greenhouse Gas - Air Pollutant Emission Control Co-Benefits: New Insights from Emission Inventory and Ambient Measurement Syntheses in Boston and Salt Lake City". Check out the full abstract here, and a copy of the poster below.
UPDATE: Arden's poster won an Outstanding Student Poster Presentation Award! Congratulations Arden!
Geddes Group @ AGU 2023
Check out all the great work from grad students and postdocs in the Geddes Research Group at this year's Fall Meeting of the AGU in San Francisco (and virtually)!
Bo Wang submitted an abstract on our work estimating the sensitivity of global ozone deposition flux calculations to various input sources: https://agu.confex.com/agu/fm23/meetingapp.cgi/Paper/1339498.
Jeff Geddes submitted an abstract on our Pandora observations in Salt Lake City: https://agu.confex.com/agu/fm23/meetingapp.cgi/Paper/1258763.
Jeff is also co-author on four additional abstracts from collaborators around the country.
Pandora User Group Meeting in DC
This week, Jeff is attending the Pandora User Group Meeting in Washington DC. This meeting brings together investigators from around the world who are operating Pandora instruments. Jeff is giving a research talk on our measurements in Boston and Salt Lake City.
Details of this meeting are shared here.
Welcome Claire!
The Geddes Group welcomes Claire Naughton, who is joining the group as a PhD student this fall. Claire has an undergraduate degree from the University of Wisconsin-Madison. Welcome Claire!
New Publications!
Fresh off the press, our group just published a pair of papers in JGR-Atmospheres on coastal urban air quality. We examine a variety of challenges and opportunities in high resolution modeling and remote sensing observations.
In postdoc Bo Wang's modeling paper, we show how sea breeze frontal dynamics and urban NOx titration effects drive strong heterogeneity in high O3 pollution that is not captured by the current monitoring network:
In grad student Taylor Adams' paper, we combine Pandora-derived NO2 column measurements with surface concentrations to constrain the role of boundary layer dynamics and to highlight the value of remote sensing in characterizing sea breeze dynamics:
These recent contributions provide new process-level insight following an earlier climatological analysis we performed with routine monitoring observations that broadly examined the role of sea breezes on air quality in the Boston area.
TEMPO Science Team Meeting in Huntsville
This week, the TEMPO Science Team Meeting is taking place at the University of Alabama, Huntsville. Jeff is participating on a panel discussing the instrument's capabilities to resolve fine spatial gradients in pollution.
This will be the first meeting since the launch of TEMPO in April (time lapse photo below, with details here)!
Seminar at MIT
This week, Jeff is the invited speaker in MIT's Program in Atmospheres, Oceans, and Climate Seminar Series. In this talk, Jeff will discuss the group's activities related to ground-based remote sensing of coastal air quality and relevance for new satellite-based observations.
American Chemical Society Meeting in Indianapolis
This week, Jeff is in Indianapolis to speak at the Spring 2023 American Chemical Society Meeting. His talk is called "Sources and Sinks in the Biosphere: Advancing the Predictive Capacity of Ecosystem-Atmosphere-Chemistry Interactions".
American Meteorological Society Meeting
This week, graduate student Rachel Mooers is in Denver presenting her work on comparing GEOS-CF predictions with observations of nitrogen dioxide derived from the TROPOMI satellite. See her abstract here:
