Picarro Trace Gases (CO, CO2, CH4, H2O) https://data.eol.ucar.edu/dataset/644.011 Summary The Picarro G2401-M instrument measures ambient trace gases (CO, CO2, CH4, H2O) reported every 2 seconds in ICARTT Format. The Picarro was deployed on the Wyoming Sprinter Mobile Laboratory (WySP) in Salt Lake City, UT during the SLC-SOS field campaign. Field calibrations of CO, CO2, and CH4 were performed using calibration tanks from NOAA and Airgas. H2O was not calibrated during the campaign and has not had calibration factors applied for this dataset.
