Description
Description
Light-absorbing particles (LAPs) deposited at the snow surface significantly reduce its albedo and strongly affect the snow melt dynamics. To better quantify the spatial variability of LAP deposition on snow, Gaillard et al. (2024) have generated a global climatology of LAP deposition on snow. It combines a climatological dataset of LAP deposition rates (Black Carbon (BC) and dust) over the period 1979-2015 (Zhao et al., 2018) with a global dataset of snow cover (Romanov, 2017) to obtain a climatology of LAP deposition rates on snow. The climatology is accompanied by the 25th and 75th percentiles of LAP deposition rates on snow to quantify the inter-annual variability of LAP deposition on snow.
The data are distributed in a NetCDF file (climato_tot_publish_v2.nc). More details about the dataset and the file format are given in the file readme_climatology_v2.pdf.
