Dust and Black Carbon in Seasonal Snow Across Northern China
Snow is the most reflective natural surface on Earth. Its albedo (the fraction of sunlight reflected) can be reduced by small amounts of dark impurities such as dust and black carbon (BC) particles. This effect is significant for climate and the hydrological cycle. BC has previously been measured in...
