UATAQ Trace Gases (NO, NO2, NOx, O3, CO2, CH4, H20) https://data.eol.ucar.edu/dataset/644.005 Summary The Utah Atmospheric Trace Gas & Air Quality (UATAQ) lab provided measurements of NO, NO2, NOx, O3, CO2, CH4, H20 at various locations in Salt Lake City, UT for the 2024-07-01 to 2024-08-31 time period. All data is valid at specific points based on location name, but the trx01 and trx02 files were NO2 measurements atop light-rail train cars in the valley. UATAQ Sites location information can be found in the UATAQ_site_config.pdf file in the Documentation section below. Additionally, these dates were removed for T200 and T400 instruments at the UOU; 6/13/24 18:55, 7/10/24 19:30, 7/19/24 10:00, 7/24/24 10:00, 7/31/24 16:45, 8/08/24 17:30, 8/13/24 18:00, 8/19/24 17:15, 8/29/24 14:15. All files are named like SLCSOS-{site}-{instrument}_{observation_type}_{start_date}_{version}.ict Identifiers * Local archive identifier: 644.005 * doi:10.26023/XWJY-BHGY-EV0V https://doi.org/10.26023/XWJY-BHGY-EV0V Versions 1.0 Citation Mineau, J., Humble, H. 2025.
