Observations of biogenic volatile organic compounds over a mixed temperate forest during the summer to autumn transition
(2022-09-26)The exchange of trace gases between the biosphere and the atmosphere is an important process that controls both chemical and physical properties of the atmosphere with implications for air quality and climate change. The ... -
Measurements of Volatile Organic Compounds in an Occupied Classroom
(2022-07-27)This dataset contains measurements of indoor air quality made in an occupied classroom at the University of Wisconsin, Madison. The measurements are described in detail in the attached readme file. Measurements include: ... -
Observation-Based Constraints on Modeled Aerosol Surface Area: Implications for Heterogeneous Chemistry
(2022-05)Heterogeneous reactions occurring at the surface of atmospheric aerosol particles regulate the production and lifetime of a wide array of atmospheric gases. Aerosol surface area plays a critical role in setting the rate ... -
Efficient production of carbonyl sulfide in the low-NOx oxidation of dimethyl sulfide
(Geophysical Research Letters, 2021-11-08)The oxidation of carbonyl sulfide (OCS) is the primary, continuous source of stratospheric sulfate aerosol particles, which can scatter shortwave radiation and catalyze heterogeneous reactions in the stratosphere. While ... -
Oceanic emissions of dimethyl sulfide and methanethiol and their contribution to sulfur dioxide production in the marine atmosphere
(Atmospheric Chemistry and Physics Discussions, 2021-10-18)Oceanic emissions of dimethyl sulfide (CH3SCH3, DMS) have long been recognized to impact aerosol particle composition and size, the concentration of cloud condensation nuclei (CCN), and Earth’s radiation balance. The impact ... -
Marine gas-phase sulfur emissions during an induced phytoplankton bloom
(2021-07)The oxidation of dimethyl sulfide (DMS; CH3SCH3), emitted from the surface ocean, contributes to the formation of Aitken mode particles and their growth to cloud condensation nuclei (CCN) sizes in remote marine environments. ... -
Simultaneous Detection of Ozone and Nitrogen Dioxide by Oxygen Anion Chemical Ionization Mass Spectrometry: A Fast Time Response Sensor Suitable for Eddy Covariance Measurements
(Atmos. Meas. Tech., Published by Copernicus Publications on behalf of the European Geosciences Union., 2020-04-01)We report on the development, characterization, and field deployment of a fast time response sensor for measuring ozone (O3) and nitrogen dioxide (NO2) concentrations utilizing chemical ionization time-of-flight mass ... -
The sensitivity of benzene cluster cation chemical ionization mass spectrometry to select biogenic terpenes
(Atmos. Meas. Tech., Published by Copernicus Publications on behalf of the European Geosciences Union., 2018-06-07)Benzene cluster cations are a sensitive and selective reagent ion for chemical ionization of select biogenic volatile organic compounds. We have previously reported the sensitivity of a field deployable chemical ionization ... -
