Arctic Methane, Carbon Aerosols, and Tracers Study Field Campaign Report
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)
The Arctic Methane, Carbon Aerosols, and Tracers Study was a measurement campaign at the National Oceanic and Atmospheric Administration (NOAA) Barrow Observatory and U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility North Slope of Alaska (NSA) sites in Barrow (formerly known as Utqiagvik) that involved the deployment of instruments to measure CH4, black carbon (BC), and source tracers. The campaign ran from September 1, 2014 to September 1, 2016 and was extended until July 30, 2017. We deployed an in situ instrument to measure methane, the ratio of its isotopologues 13CH4/12CH4, and ethane. We deployed a second instrument to measure carbon monoxide, carbonyl sulfide (COS), carbon dioxide, and water vapor. We also deployed an in situ instrument to measure BC, a single-particle soot photometer (SP2), at the nearby NOAA Barrow Observatory, co-located with the other NOAA aerosol instruments. Changes in emissions across different regions and seasons will be inferred using atmospheric transport and inverse modeling techniques.
