Measurements of volatile organic compounds in the Northern Colorado Front Range in 2023

This dataset was collected by Colorado State University (CSU) students
during the spring 2023 and fall 2023 semesters as part of a course in the
Department of Atmospheric Science (ATS-716: Air Quality Characterization).
Measurements of volatile organic compounds (VOCs) were collected in
Northern Colorado, using a low-cost sensor called SENSIT SPOD. The SENSIT
SPOD sensor package combines wind field and air pollutant concentration
measurements to detect emission plumes and locate the source of those
emissions. The sensor measures non-speciated, uncalibrated concentrations
of a subset of VOCs. The sensor also measures temperature, relative
humidity, pressure, and wind direction and speed. The SPODs were used to
trigger the collection of whole air samples during periods with higher
concentrations of VOCs. Air samples from the triggered canisters were
analyzed at CSU using Gas Chromatography (GC) to provide a measure of
approximately 50 VOCs. An integrated canister was used to measure the
average concentration of approximately 50 VOCs over a one-week period.
After collection, sample air in the canisters was analyzed at CSU using
Gas Chromatography (GC).
