Supporting Stations: Palmer Station
The National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory Global Monitoring Division (ESRL-GMD) will continue long-term measurements of ultra-violet (UV) radiation that influences climate and the ozone layer. The observations are made in conjunction with ongoing worldwide measurements of carbon dioxide, methane, carbon monoxide, aerosols, water vapor, surface and stratospheric ozone, chlorofluorocarbons, and the ozone layer. The measurements are used for time-series analysis of multi-year data focusing on stratospheric ozone depletion, trans-Antarctic transport and deposition, the interplay of trace-gas aerosols with the solar and terrestrial radiation fluxes on the polar plateau, the magnitude of seasonal and temporal variations in greenhouse gases, and the development of polar stratospheric clouds over Antarctica.
Field Season Overview
The Palmer Station Research Assistant (RA) provides year-round support for the UV monitoring instruments. One participant is scheduled to deploy to Palmer in March 2023. Additionally, the RA performs Scripps, CCGG, and HATS air sampling. A site visit to the NOAA Boulder location is required prior to RA deployment. Additional training is provided for the Research Associate during turnover between RAs on the Ice.
