Arctic snow black carbon concentrations, and absorption by other light-absorbing aerosol
These data give estimates of black carbon (BC) mixing ratios from samples of snow or melting sea ice gathered by ourselves or by volunteers, mostly from 2006 to 2009 but with some data from earlier years. Almost all samples were collected in the spring season (March to early May) when the combinatio...
