New Pandora Papers Published!
Our group recently published two new papers on Pandora data collected in the Boston area:
(1) "Sampling sub-pixel scale variability in total column NO2 within a coastal urban environment: Observations from Pandora and implications for satellite remote sensing" published in Environmental Science: Atmospheres.
Taylor Adams shows how well Pandoras can capture neighborhood-scale variability in nitrogen dioxide, and shifts in emissions over time, that remain unresolved by current satellite observations even after oversampling.
(2) "Observing complexity in the evolution of formaldehyde in a coastal urban environment with Pandora spectrometer" published in Environmental Science: Atmospheres.
Claire Naughton shows that elevated formaldehyde in Boston is often driven by the entrainment of long-range transport inputs during boundary layer development, a process that is not temporally resolved by traditional EPA HCHO sampling.
TEMPO Data, Applications, Research, and Technology (DART) Meeting
This week Jeff attended the TEMPO DART meeting hosted at the University of Iowa in Iowa City. He presented a talk titled, "Seeing the Daily Cycle: Examining Diurnal Patters in TEMPO and Pandoras".
International GEOS-Chem Meeting in St Louis
This week Jeff and Matt were in St. Louis for the 12th International GEOS-Chem Meeting hosted at Washington University St. Louis. Matt discussed his work looking at long-term trends and variability in NH3, and Jeff discussed the FarmFlux mission.
FarmFlux Science Team Meeting
The very first FarmFlux Science Team meeting was hosted at Colorado State University in Fort Collins this week. It was terrific to get all the science PIs together and chat about our exciting plans. Our first flights with the small aircraft will begin this fall!
Geddes Group @ AGU New Orleans
This week, members of the Geddes group are presenting work at the American Geophysical Union meeting in New Orleans:
- Claire Naughton, Connecting Surface-Column HCHO Observations Using Pandora Spectrometers in a Coastal Urban Environment.
- Rachel Mooers, Mapping NO2 Variability with a Custom Pandora Sky Scan Azimuth Schedule at Multiple Locations in Boston.
- Anthony Wong, Warming-Induced Increases in Agricultural Soil NH3 and NOx Emissions Could Worsen PM2.5 Air Quality.
Jeff is also a co-author on the following presentations:
- Masoud Ghahremanloo, Comprehensive Analysis of Bias in TEMPO NO₂ Column Densities & Generating Deep-Learning-Based TEMPO Products.
- Xiong Liu, A New Era of Air Quality Monitoring from Space over North America with TEMPO: Mission Status from First Two Years in Orbit.
Seminar at the Center for Astrophysics | Harvard & Smithsonian
Today, Jeff is giving the Atomic and Molecular Physics Seminar at the Center for Astrophysics | Harvard & Smithsonian in Cambridge MA.
The title of his talk is "From the Satellite to the Street: Urban Air Quality Insights from Ground-BaseD Remote Sensing".
TEMPO Science Team Meeting
This week, Rachel Mooers and Jeff Geddes are attending the TEMPO Science Team Meeting at the Center for Astrophysics | Harvard & Smithsonian in Cambridge MA.
Rachel is presenting a poster called "TEMPO versus Pandora NO2 in U.S. Cities".
Jeff is presenting a talk called "A Closer Look at Diurnal Variability from TEMPO and Pandora Measurements in Boston and Salt Lake City".
Telluride Workshop on Mapping Urban Air
This week, Jeff is attending a workshop hosted by the Telluride Science & Innovation Center. The title of the workshop is: "Mapping Urban Air: Linking Observations and Processes". Jeff will be presenting work on our group's Pandora measurements in Boston and Salt Lake City, emphasizing the importance of these ground-based observations in interpreting new data from the TEMPO satellite instrument.
Atmospheric Chemistry Gordon Research Conference
This week, Jeff is attending the Atmospheric Chemistry Gordon Research Conference in Maine. He is presenting a poster titled "Mapping Urban Air Quality with Remote Sensing".
Congrats Arden!
We congratulate Arden Radford on a successful PhD defense! Thanks for all the dedication, hard work, and collegiality, Arden! Your contributions have been immensely appreciated by our group and the BU community.
