Local and Regional Contributions to Tropospheric Ozone Concentrations
Callum E. Flowerday, Ryan Thalman, Jaron C. Hansen
The Wasatch Front in Utah, USA, is currently a non-attainment area for ozone according to the Environmental Protection Agency's (EPA) National Ambient Air Quality Standards (NAAQS)…
Twenty-Year Review of Outdoor Air Quality in Utah, USA
Callum E. Flowerday, Ryan Thalman, Jaron C. Hansen
Air quality is a prevalent concern due to its imposing health risks. The state of Utah, USA, has, at times over the last 20 years, experienced some of the worst air quality in the…
Broadband Cavity-Enhanced Absorption Spectroscopy (BBCEAS) Coupled with an Interferometer for On-Band and Off-Band Detection of Glyoxal
Callum E. Flowerday, Ryan Thalman, Matthew C. Asplund +1
Glyoxal CHOCHO is a trace gas in the atmosphere, often used as an indicator of biogenic emissions. It is frequently compared to formaldehyde concentrations, which serve as indicato…
Detection of Sulfur Dioxide by Broadband Cavity-Enhanced Absorption Spectroscopy (BBCEAS)
Ryan Thalman, Nitish Bhardwaj, Callum E. Flowerday +1
Sulfur dioxide () is an important precursor for the formation of atmospheric sulfate aerosol and acid rain. We present an instrument using Broadband Cavity-Enhanced…
Absorption cross-sections for the 5th and 6th vibrational overtones in a series of short chained alcohols using incoherent broadband cavity enhanced-absorption spectroscopy (IBBCEAS)
Callum E. Flowerday, Nitish Bhardwaj, Ryan Thalman +3
Absorption cross-sections for the 5th (6 0) and 6th (7 0) OH overtones for gas-phase methanol, ethanol, and isopropanol were measured using a slow flow ce…
Deconvolution of Interplanetary Transport of Solar Energetic Particles
D. Ruffolo, T. Khumlumlert, W. Youngdee
We address the problem of deconvolving the effects of interplanetary transport on observed intensity and anisotropy profiles of solar energetic particles with the goal of determini…
