Field Campaigns

A major component of my research involves traveling around the US and the world to sample the composition of the atmosphere. These campaigns are often large collaborative efforts involving multiple institutions and an army of dedicated scientists. The list below includes those in which I have been involved, through measurements and/or subsequent data analysis.

NTERFAACE, Summer 2026(?): NASA mission focused on rates and fates of U.S. agricultural emissions.

GOTHAAM, Summer 2025(?): Detailed study of the complex marine, biogenic, and urban processes controlling air quality in the New York Metropolitan Area. Sponsored by NSF.

ALEGROS, Summer 2024: NASA and EPA-sponsored intensive flights to map concentrations and emissions of reactive and greenhouse gases in U.S. cities (Baltimore, Philadelphia, Los Angeles, and others) under TEMPO satellite observations. 

ASIA-AQ, Winter 2024: NASA-led investigation of air quality in multiple Asian countries, including Philippines, Korea, Thailand, and Taiwan. Also the last mission of the DC-8.

AEROMMA, Summer 2023: NOAA mission to investigate marine and U.S. urban photochemistry.

BlueFlux, 2022 - 2024: NASA Carbon Monitoring System mission to map the surface-atmosphere exchange of carbon dioxide and methane in southern Florida (Everglades and Big Cypress National Parks)

ACCLIP, Summer 2022: NASA/NSF joint mission on upper tropospheric outflow from the Asian Monsoon.

FIREX-AQ, Summer 2019: NASA/NOAA joint mission to understand the emissions and fate of smoke from wild and agricultural fires.

SARP, Summer 2017-ongoing: NASA's Student Airborne Research Program, designed to immerse undergraduate rising seniors in NASA's suborbital research (not just chemistry!).

CARAFE,  Fall 2016 and Spring 2017: First-ever airborne observations of carbon dioxide, methane, and heat fluxes using the NASA C-23 Sherpa.

ATom, 2016 - 2018: A series of four around-the-world missions on the NASA DC-8 to map the background composition of the troposphere.

KORUS-AQ, Spring 2016: Flying a new compact formaldehyde instrument on the Hanseo King Air to characterize air quality in South Korea. 

SONGNEX, Spring 2015: Airborne measurements on the NOAA WP-3D over shale oil and natural gas extraction regions.

WINTER, Winter 2015: An airborne campaign on the NSF C-130 to examine near-surface chemistry throughout the Eastern US whens its cold.

CONTRAST, Winter 2014: An airborne campaign on the NSF G-V studying surface-to-TTL (50,000 ft) transport and convection in the tropical western Pacific.

SEAC4RS, Summer 2013: An airborne campaign using the NASA DC-8 and ER-2 aircraft to study composition-cloud-climate coupling throughout the US.

SOAS, Summer 2013: Ground and tower-based observations in the heart of the "isoprene volcano" to characterize chemistry at the urban-rural interface and its impacts on air quality and climate.

SENEX, Summer 2013: Airborne measurements on the NOAA WP-3D to investigate the interaction of urban pollution with natural emissions in the southeast US.

PEGASOS, Spring/Summer 2012:  Zeppelin-borne observations of near-surface gas-phase, aerosol and physical processes within contrasting photochemical regimes.

BEACHON, Summer 2010:  Ground-based observations aimed at characterizing biosphere-atmosphere interactions in a Ponderosa pine forest.

ACCRONIM, Winter 2009:  A ground-based intensive to characterize the role of chlorine in continental multi-phase processing of pollutants.

ICEALOT, Winter 2008:  A ship-based research cruise to map out atmospheric chemistry in the North Atlantic Arctic spring.

BEARPEX, Summer 2007 and 2009:  Tower observations in a rural forest to study the synergy of anthropogenic and biogenic influences at the urban-rural interface.

INTEX-B, Spring 2006:  Ground-based measurements to assess the impact of trans-Pacific pollutant transport on atmospheric composition in the US.
