Dust FluxJouzel et al. 1987 Click here to download dataThis file contains age, flux (in milligrams of dust per year per square meter). This was deduced from the published data (Petit et al., 1990) assuming a dust density of 2. Original data are smoothed using a spline function. This file is not as complete as the dust concentration data given above. Note that the calculation of flux assumes knowlegde of the snow accumulation rate; the calculation here assumes the original Lorius et al. (1987) age-depth and vertical strain model.
