Description

The National Oceanographic and Atmospheric Administration (NOAA) Global Monitoring Division (GMD) team will continue long-term measurements of trace constituents that influence climate and the ozone layer. The work done at Palmer Station is in conjunction with the ongoing worldwide measurements of carbon dioxide, methane, carbon monoxide, aerosols, water vapor, surface and stratospheric ozone, chlorofluorocarbons, and the ozone layer. This is part of NOAA's effort to determine and assess long-term buildup of global pollutants in the atmosphere. Measurements will be used for time-series analysis of multi-year data records that focus on the stratospheric ozone depletion; trans-Antarctic transport and deposition; interplay of trace-gas aerosols with polar plateau solar and terrestrial radiation fluxes; magnitude of seasonal and temporal variations in greenhouse gases; and polar stratospheric cloud development over Antarctica.

Field Season Overview

The Palmer Station Research Assistant will provide year-round support for the UV monitoring instruments. Typically there are site visits by one NOAA UV instrument technician every two years. Additionally, the RA performs Scripps, CCGG, and Halocarbon and other Atmospheric Trace Gasses (HATS) air sampling. Due to the COVID-19 pandemic impacts, visits scheduled for 2020-21 have been deferred to a later date.
