Publications concerning this project

Six, D., M. Fily, S. Alvain, P. Henry, and J-P. Benoist, 2004: Surface Characterisation of the Dome Concordia area (Antarctica) as a potential satellite calibration site, using Spot 4/Vegetation instrument. Remote Sensing of Environment, 89, 83-94. In this study, the snow surface of the high plateau of the East Antarctic Ice Sheet, particularly the Dome C area (75°S, 123°E), is used first to test the quality of this site as a ground calibration target and then to determine the inter-annual drift in the sensitivity of the VEGETATION sensor, onboard the SPOT4 satellite.

Hudson, S.R. and R.E. Brandt, 2005: A Look at the Surface-Based Temperature Inversion on the Antarctic Plateau. J. Climate, 18, 1673-96. This paper analyzes several aspects of the temperature inversion near the Antarctic snow surface. While the work was conducted primarily as part of the SPARCLE project, it contains some data collected during this project at Dome C.

Hudson, S.R., S.G. Warren, R.E. Brandt, T.C. Grenfell, and D. Six, 2006: Spectral Bidirectional Reflectance of Antarctic Snow: Measurements and Parameterization. J. Geophys. Res., 111, D18106, doi:10.1029/2006JD007290. This paper presents the BRDF observations we made at Dome C along with a parameterization for the anisotropic reflectance factor of Antarctic snow.

Warren, S.G., R.E. Brandt, and T.C. Grenfell, 2006: Visible and Near-Ultraviolet Absorption Spectrum of Ice from Transmission of Solar Radiation into Snow. Appl. Opt., 45, 5320-5334, doi:10.1364/AO.45.005320. This paper shows a derivation of the absorption spectrum of ice at wavelengths 350 to 600 nm. This absorption spectrum was inferred from measurements of the transmission of light into the snow at Dome C, and it resolves previous discrepencies between laboratory and similar field measurements.

Hudson, S. R. and S. G. Warren, 2007: An Explanation for the Effect of Clouds over Snow on the Top-of-Atmosphere Bidirectional Reflectance. J. Geophys. Res., in press.This paper uses the BRDF parameterizations from Hudson et al. 2006 to explain the effects clouds over snow on the directional reflectance seen by satellites.
