This 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.
