Abstract
Nitrogen oxides (NOX), including nitric oxide (NO) and nitrogen dioxide (NO₂), are atmospheric constituents that can contribute to nitrate deposition in seawater. Since nitrate availability can influence marine ecosystems, understanding atmospheric nitrogen inputs is important for characterizing nitrogen cycling in coastal environments. This dataset contains atmospheric NO and NO₂ measurements collected from July 5–6, 2023, in the marine boundary layer near Tampa Bay, Florida, at the University of South Florida St. Petersburg campus using a Teledyne T200UP Analyzer.
The dataset provides observations of atmospheric nitrogen oxide concentrations that can be compared with measurements of nitrate in rainwater and seawater to investigate potential sources and correlation of atmospheric nitrogen and nitrogen entering coastal waters. During the measurement period, NO₂ concentrations were generally 1–10 ppb, while NO concentrations were primarily 0–5 ppb, with occasional concentration spikes of 30 ppb. The measured NOX levels were consistent with typical marine boundary layer values and previous research. Researchers can reuse these data to reproduce analyses, compare atmospheric nitrogen concentrations across locations or time periods, validate atmospheric models, and support future research on coastal air quality, atmospheric nitrogen deposition, and marine nitrogen cycling. The dataset may also provide useful training or validation data for environmental data analysis and machine learning applications.
The Weather Climate and Society REU program invited 10 students from across the US to conduct research projects related to disaster-vulnerable communities in Florida and other extreme weather-affected areas. These projects were interdisciplinary, integrating social science and physical science aspects of severe weather, climate, and related disasters through field work, interviews, and/or spatial analysis of secondary data in GIS. The PI of this REU is Dr. Jennifer Collins.
