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!

By Jeffrey GeddesJune 6th, 2023in News

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

By Jeffrey GeddesMay 1st, 2023in News

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)!

WMO Measurement-Model Fusion for Global Total Atmospheric Deposition Workshop

By Jeffrey GeddesOctober 6th, 2022in News

This week, Jeff is participating in the World Meteorological Organization's Measurement-Model Fusion for Global Total Atmospheric Deposition Workshop, being held virtually and in person in Geneva.

Jeff is giving two talks about research and developments in the Geddes Group: (1) "A Pilot Project for Operational Global O3 Surface Flux Estimates"; and (2) "What is the View from Space? Opportunities and Challenges in Satellite-Informed Methods for Total Atmospheric Deposition Estimates".

Visiting Salt Lake City

By Jeffrey GeddesAugust 18th, 2022in News

This week, Jeff is in Salt Lake City visiting the University of Utah. He is checking in on our Pandora deployment, and giving a seminar for the Department of Atmospheric Sciences seminar series. The title of his talk is, "Challenges and Opportunities in Coastal Urban Air Quality Monitoring: Lessons from the Boston Basin".
