Antarctic moisture flux and net accumulation from global atmospheric analyses

CO2 flux history 1982–2001 inferred from atmospheric data using a global inversion of atmospheric transport

Based on about 20 years of NOAA/CMDL’s atmospheric CO2 concentration data and a global atmospheric tracer transport model, we estimate interannual variations and spatial patterns of surface CO2 fluxes in the period 01/1982–12/2000, by using a time-dependent Bayesian inversion technique. To increase the reliability of the estimated temporal features, particular care is exerted towards the select...

Atmospheric concentrations and air-water flux of organochlorine pesticides along the Western Antarctic Peninsula.

Air, seawater, sea ice, and snow were collected during the austral winter (September-October 2001) and summer (January-February 2002) along the Western Antarctic Peninsula. Hexachlorobenzene (HCB) > heptachlor > alpha- and gamma-hexachlorocyclohexane (HCH) and heptachlor epoxide, were the most frequently detected organochlorine pesticides in air. HCB and HCH levels declined over the past 20 yea...

Spatial and Temporal Variability of Antarctic Precipitation from Atmospheric Methods

The spatial and temporal variability of net precipitation (precipitation minus evaporation/sublimation) for Antarctica derived from the European Centre for Medium-Range Weather Forecasts operational analyses via the atmospheric moisture budget is assessed in comparison to a variety of glaciological and meteorological observations and datasets. For the 11-yr period 1985–95, the average continent...

Atmospheric Soundings of Temperature, Moisture and Ozone from AIRS

Antarctic atmospheric temperature trend patterns from satellite observations

[1] Tropospheric temperatures in the Antarctic are retrieved by linearly combining satellite-borne Microwave Sounding Unit (MSU) channels 2 and 4 observations. We show good agreement between satellite-inferred temperature trends and radiosonde observations. It is illustrated that the Antarctic troposphere has cooled in the summer and fall seasons since 1979, in agreement with Thompson and Solom...
