Abstract

Changes in snow reflectivity as a function of dustfall were used to measure dust deposition rates in terms of satellite reflectivity data. The results show that for dry snow conditions, snow reflectivity can be approximated by Kubelka-Munk theory. Dustfall above threshold values of 10μg/cm2 can be detected using Land-sat computer tape data. Determination of dust deposition over ice-covered lakes and harbors appears in good agreement with sampling measurements.
