Supporting Stations: McMurdo Station, South Pole Station
The National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ESRL) GMD will continue long-term measurements of ultra-violet (UV) radiation that influences climate and the ozone layer. The McMurdo Station work is 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 will be used for time-series analysis of multi-year data focusing on stratospheric ozone depletion; trans-Antarctic transport and deposition; interplay of the trace-gases 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
At South Pole Station, the Atmospheric Research Observatory (ARO) will be used for the NOAA instrument suite and the management of the Clean Air Sector. Two NOAA personnel will staff the observatory year around. Scientists will deploy for short periods throughout the austral summer performing upgrades and routine maintenance on the instruments at the South Pole and working at the ARO, in addition to the two core staff.
