EPCAPE-PT-LANL Measurements: Gas Monitors
- ORNL
Coastal cities offer a unique environment for studying aerosol-cloud interactions and the effects of urban emissions on cloud properties. As part of the Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE), the Partitioning Thrust by Los Alamos National Laboratory (EPCAPE-PT-LANL) was conducted. Our campaign focused on measuring the optical and chemical properties of aerosols and their interactions within marine stratocumulus clouds in La Jolla, California. EPCAPE-PT-LANL enhances the primary goals of EPCAPE through innovative observations of vapor-phase transitions between aerosols and cloud droplets, the impact of black carbon on aerosol-cloud dynamics, and the effects of cloud processing on aerosol optical properties.
Instrument: G2401 Gas Concentration Analyzer (Picarro)
Data Notes: The Picarro G2401 gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.
Header:
- CO[ppm]: Concentration of carbon monoxide (CO) measured at the time of sampling, expressed in parts per million (ppm).
- CO2[ppm]: Concentration of carbon dioxide (CO2) measured at the time of sampling, expressed in parts per million (ppm).
- CH4[ppm]: Concentration of methane (CH4) measured at the time of sampling, expressed in parts per million (ppm).
- H2O[%]: Water vapor content in the air at the time of the measurement, expressed as a percentage
