About Us

Researchers in the Atmospheric Chemistry Group study soluble acidic gases and aerosols in the Earth’s atmosphere that can scatter and absorb sunlight, thus impacting air quality and climate. We have led complex international airborne campaigns — often involving both remote sensing and in situ sampling approaches — to take comprehensive measurements of gases and aerosols in the atmosphere, as well as the microphysics of those aerosols. In addition, we also investigate urban air quality involving partnerships with the community.

The group currently includes two PIs; Jack Dibb and Katharine Duderstadt, and occasional undergraduate researchers.

Atmospheric Impacts of Energetic Particles

We use the Whole Atmosphere Community Climate Model (WACCM-CESM) from the National Center for Atmospheric Research (NCAR), combined with spacecraft and ground-based observations, to quantify the atmospheric impacts of energetic particles from the Earth’s magnetosphere, the Sun, and our galaxy. These high-energy electrons, protons, and ions increase hydrogen oxide radicals (HOx) and nitrogen oxides (NOx) in the upper atmosphere, accelerating the destruction of stratospheric ozone (O₃) and potentially affecting global climate. The Atmospheric Chemistry Group collaborates with researchers in the Space Science Center, NCAR, NASA, and Boston University to integrate space-based measurements — such as data from NSF FIREBIRD CubeSats, NASA Van Allen Probes, and NOAA POES spacecraft, including instruments developed at UNH—into atmospheric model simulations to assess these impacts.

Air Pollution and Community Science

We are also developing expertise in community science, combining atmospheric modeling, low-cost air quality sensors, and community observations to help residents understand local air pollution. By integrating scientific tools with community knowledge, we provide actionable information that enables people to respond and protect their health. We work with partners such as the American Geophysical Union’s Thriving Earth Exchange, environmental advocacy nonprofits, community organizers, and residents to design and carry out projects. These collaborations also give undergraduate students hands-on research experience, allowing them to apply their skills to address real-world community needs.

After a two-year break due to COVID-19 precautions, large collaborative field campaigns began again in 2022

Alaskan Layered Pollution and Chemical Analysis (ALPACA) Field Experiment

The Alaskan Layered Pollution And Chemical Analysis (ALPACA) field experiment was a collaborative study designed to improve understanding of pollution sources and chemical processes during winter (cold climate and low-photochemical activity), to investigate indoor pollution, and to study dispersion of pollution as affected by frequent temperature inversions. A number of the research goals were motivated by questions raised by residents of Fairbanks, Alaska, where the study was held.

Jack participated in the ALPACA air quality campaign in Fairbanks, January-February, 2022. He collected aerosol on filters and surface snow samples several times per day. Snowpits were also sampled down to the ground at the beginning, middle and end of the campaign.  All samples were analyzed (using our groups established techniques) in a lab at UAF immediately after sampling.

It turned out that COVID cases were still ramping up in Alaska in early 2022, peaking in Fairbanks in the middle of the campaign. Precautions taken by our large international team limited exposure and cases, but also limited the face to face interactions that make collaborative field work great for building and strengthening networks.

Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ)

The Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) is an international cooperative field study designed to address local air quality challenges. Specifically, ASIA-AQ will contribute to improving the integration of satellite observations with existing air quality ground monitoring and modeling efforts across Asia. 

Jack served as Co-mission scientist for the NASA DC-8 during ASIA-AQ, February – March, 2024. He flew as platform scientists on all of the flights, characterizing the composition of the atmospheric boundary layer above large urban areas (and the surrounding rural regions) in the Philippines, South Korea, Thailand, and Taiwan.

Quality-controlled data were released by all members of the team late in 2024 with analysis and preparation of papers in progress.

Student Airborne Research Program (SARP)

The Student Airborne Research Program (SARP) is an eight-week summer internship for rising-senior undergraduates, held annually on the East and West coasts of the United States. Students gain hands-on research experience in all aspects of a scientific campaign by engaging in field research and data analysis, with access to one or more NASA Airborne Science Program flying science laboratories. 

Students will not only participate in airborne data collection, but also take measurements at field sites. Using data from the campaign and NASA's extensive archive, they will design, implement, and present their own independent research projects. Throughout the process, students are supported by a team of faculty and graduate mentors who guide them as they develop their research skills. The program concludes with a 12-minute scientific presentation, where students share the results of their research.

Mid-Atlantic Gas Emissions Quantification (MAGEQ)

 In summer 2025, NASA has multiple aircraft in the MD/VA area flying for separate missions. Leveraging these systems in a coordinated fashion  allows us to better support GHG Center priorities and needs of local stakeholders.

  • Demonstrate and compare emissions estimation techniques in priority regions – urban, wetland, agricultural, and coal mining areas
  • Prototype methodology for scaling from detailed measurement periods to annual estimates needed by stakeholders
  • Complement ground observations with airborne data to improve utility of satellite observations for environmental management

Jack served as platform scientist/nominal PI for the NASA P3 during SARP and MAGEQ, June–July, 2025.

Sunlight Absorption of the Greenland ice sheet Experiment (SAGE)
[NASA Interdisciplinary Science Program]

Our group quantified black carbon (BC) and major soluble ions (including tracers of dust and biomass burning smoke) in ~ 5000 snow samples collected from 65 snow pits in the central and northwestern portions of the Greenland ice sheet. Fieldwork was conducted by collaborators at Dartmouth College and CRREL via surface traverses in the spring of 2013 and 2014. Our results were instrumental in showing that on the high plateau of the ice sheet the abundance of BC and dust is too small to have a significant impact on albedo (hence snow melt) and did not contribute to the record wide spread melt event in summer 2012. We have also shown that the combination of satellite data products and a state of the art regional chemical transport model can connect BC from smoke in the snow in Greenland to specific fires, but the model does not accurately simulate the amount of BC that is deposited to the snow which is critical to estimate the likely impact of increasing wildfires on the contributions of Greenland melt to global sea level. The team is wrapping up several additional papers which will show that: a lot of processes need to combine in a precise way to deposit enough smoke derived BC on Greenland that it could promote melt (many smoke plumes pass over the ice sheet but leave little or no signal in the snow), and that BC in the snow is more significant climatically than BC in the atmosphere. In fact, smoke over the ice sheet tends to cool the surface snow despite warming the layer of the atmosphere containing the smoke and exerting positive forcing at the top of the atmosphere. 

Korean-US Air Quality Mission (KORUS-AQ)
[NASA Tropospheric Chemistry Program]

The KORUS-AQ mission is a collaborative analysis of Korean air quality conducted between NASA and the Korean National institute of Environmental Research (NEIR). The mission field work was completed in spring of 2016 and utilized measurements from several aircraft, marine vessels, and satellites. The combined data set is one of the largest yet compiled by NASA in a single mission of this type. The primary objectives of the mission aim at understanding the dynamic processes affecting the atmosphere of western Asia, and those impacts on the Korean Peninsula. South Korean atmosphere is in constant flux from biogenic and anthropogenic inputs both domestic and from abroad and complex meteorology adds further levels of seasonal variation. The Atmospheric group of the UNH ERSC played a major role in airborne measurements during the mission. Operating several instruments onboard the NASA DC-8 flying laboratory, both gas and particle phase chemistry were measured. Some major constituents measured by the group include the soluble ions (Ca2+, Mg2+, SO42-,NO3-, Cl-,Br-) as well as gas phase HN03. Current research is focused on understanding how Asian dust acts as a transport mechanism for anthropogenic pollution produced in the industrial centers of eastern China to the Korean mainland. Asian dust is quite pervasive in Korea and regularly leads to visibility and health problems; the loading of anthropogenic acids further complicates the negative effects of dust. Current research will be presented at the 2017 American Geophysical Union’s annual meeting in New Orleans. 

Atmospheric Tomography Mission (ATom)
[NASA Earth Venture Suborbital Program]

Between 2016 and 2018, we are participating in a campaign dubbed the Atmospheric Tomography Mission, or “ATom”. With a team of about 25 research groups from around United States in addition to aircraft personnel, we are studying human produced pollution, greenhouse gasses, and how reactive gasses interact in the remote troposphere and lower stratosphere (0.2 – 12 km). Understanding of the production of, lifetime, and impacts on chemistry and radiative forcing of fine particulate (aerosols) is also a very high priority. All of these measurements are used to improve the predictive capability of global climate models while helping validate space based remote sensors. This series of campaigns consists of 4 month-long global scale science campaigns (August, 2016; February and October, 2017; and May 2018) flying the DC-8 mobile laboratory around the world from its home base in Palmdale, California. Destinations along the route include Anchorage, Alaska; Kona, Hawaii; Nadi, Fiji; Christchurch, New Zealand; Punta Arenas, Chile; Ascension Island; Terceira, Azores; and Thule, Greenland. Flights to Alaska and Greenland extend to ~ 80 N and for the last two campaigns we will fly South from Chile to ~ 75 S. Each flight consists of making measurements while continuously profiling from 500 feet above sea level to the maximum altitudes that the plane can safely achieve to get a comprehensive representation of the surrounding environment. A concerted effort is being made to make this data available for public use as soon as possible. Currently, as of August 2017, the data collected during the first campaign (August, 2016) is available at the NASA Earth Science Project Office website. https://espoarchive.nasa.gov/archive/browse/atom with a planned release of the February, 2017 data in December, 2017. 

Fire Influence on Regional and global environments Experiment (FIREX)
[NOAA Climate Program]

FIREX is a study on “The Impact of Biomass Burning on Climate and Air Quality: An Intensive Study of Western North America Fires”. Our contributions will be collaborative studies with researchers from Brown University; 1) at the Forest Service firelab in Missoula, some of which have already been conducted, and 2) sampling wildfire smoke plumes from a mobile lab over the summers of 2018 and 2019. Our sampling is focused on nitrogen oxide compounds, with measurements designed to determine both concentration and isotopic composition of NOx (= NO + NO2), HNO3, HONO and aerosol nitrate in wildfire smoke in the Western United States. There will be focus on taking measurements at night, as well as during the day, to potentially fill in gaps in current scientific knowledge especially by sampling closer to fires and much closer to the ground than the NOAA, NASA and NSF aircraft also participating in the study will be able to. NOx compounds play an important role in the oxidation capacity of the atmosphere, and are the primary source of HNO3 and particulate nitrate; two major contributors to acid rain and nitrogen deposition. Nitrogen oxide compounds found in wildfire smoke can be transported long distances and have far reaching impacts on air quality, climate and ecosystem health. NOx contributions from wildfires have seasonal impacts on pristine regions that are particularly sensitive to regional haze and nitrogen deposition. Isotopic composition tracking has the potential to enhance understanding of the transformation and fate of NOx compounds as they move further from the fire source.

Atmospheric Impacts of Energetic Particles (Sun-to-Ice)
[NSF Frontiers in Earth System Dynamics]

Simulations using the Whole Atmosphere Community Climate Model (WACCM-CESM) from the National Center for Atmospheric Research (NCAR) combined with observations from spacecraft and ground-based monitors allow us to quantify atmospheric impacts of energetic particles from the Earth’s magnetosphere, the Sun, and our galaxy. These high-energy electrons, protons, and ions can enhance hydrogen oxides radicals (HOx) and total reactive odd nitrogen (NOy) in the upper atmosphere, leading to the destruction of stratospheric ozone (O3) and potentially influencing global climate. Members of the Atmospheric Chemistry Group have been working with researchers in the Space Science Center to quantify these atmospheric impacts, using space-based data from instruments developed at UNH (e.g., on board the NSF FIREBIRD CubeSats and NASA Van Allen Probes spacecraft) as input to atmospheric model simulations. Solar and galactic cosmic rays that fluctuate with solar activity also produce radioactive isotopes such as 14C, 10Be, and 36Cl in the atmosphere that are eventually sequestered at the surface in paleoclimate archives such as ice cores and tree rings. Our hope is to combine satellite and ground-based measurements of cosmic rays, global climate modeling, and paleoclimate archives to develop reconstructions of historical solar activity. Understanding past solar activity will greatly improve the ability to predict the frequency and strength of future solar storms as well as possible solar influences on global and regional climate. We are also conducting WACCM simulations of 7Be, a relatively short-lived radioisotope produced in the upper atmosphere by cosmic rays, along with 222Rn (and decay product 210Pb), a radioisotope emitted at the Earth’s surface. Comparisons of model results with global observational networks can enhance our understanding not only of energetic particle impacts but also stratosphere-troposphere exchange and aerosol deposition. The plan is to compare these WACCM simulations with similar work being done using the GEOS-Chem model.
