Project Description:
At the South Pole, NOAA's Global Monitoring Division (GMD) collects year-round long-term measurements of trace atmospheric constituents that influence climate change. These measurements are part of NOAA's effort to determine and assess the long-term build-up of global pollutants in the atmosphere. The measurements are used for time-series analysis of multi-year data records that focus on stratospheric ozone depletion, trans-Antarctic transport and deposition, interplay of the trace gases and aerosols with 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. Other objectives of the research are to determine the rate at which concentrations of these atmospheric constituents change and to examine the sources, sinks, distributions, budgets and trends. The data help climate modelers and diagnosticians determine how the rate of change of these parameters affect climate, particularly when the data are included in climate-model studies.

Field Season Overview:
Each austral summer, two project team members staff the Atmospheric Research Observatory (ARO). Other personnel deploy for shorter periods throughout the field season to perform upgrades and routine maintenance on the instruments. Over the austral winter, two NOAA personnel will remain on station to continue observations and measurements.

Deploying Team Members:

  • Kelli-Ann Bliss
  • Ross Burgener
  • James Butler (PI)
  • Joseph Phillips
  • William Roth
  • Sebastian Stewart
