Supporting Stations: McMurdo Station, South Pole Station
The National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ESRL) GMD will continue measurements of ultra-violet (UV) radiation that influences climate and the ozone layer. 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. Measurements will be used for time-series analysis of multi-year data records that focus on stratospheric ozone depletion; trans-Antarctic transport and deposition; interplay of trace-gas aerosols with polar-plateau solar and terrestrial radiation fluxes; the magnitude of seasonal and temporal variations in greenhouse gases; and the development of polar stratospheric clouds over Antarctica.
Field Season Overview
Operational requirements will continue as before, with the use of the Atmospheric Research Observatory (ARO) for the NOAA instrument suite and the management of the Clean Air Sector. A minimum of two NOAA personnel will staff the observatory year-round. 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. At no time will the NOAA/GMD South Pole ARO staffing be less than two. The need for space and logistics support for balloon launching will continue with only minor changes. The use of helium will continue with no changes. Air samples will be returned to NOAA/GMD in Boulder, Colorado on a regular schedule for analysis of carbon dioxide and other trace constituents.
