Role of graphitic carbon particles in radiative transfer in the arctic haze

摘要: Large concentrations of combustion-generated graphitic carbon particles have been identified at ground level and altitude in the Arctic atmosphere. Concentrations these during certain times year altitudes are comparable to those urban centers United States. These particles, which a structure similar black, on molecular using Raman spectroscopy sites Alaskan, Canadian, Norwegian Arctic. The black very effective absorbers solar radiation can lead significant heating effects, depending primarily their distribution time space. Recent measurements from an airplane indicate that high occur throughout troposphere, be significantly higher than level. implications results radiative transfer will discussed.
