Exposure of black carbon (BC) is associated with a variety of adverse health outcomes. A number of optical methods for estimating BC on Teflon filters have been adopted but most assume all light absorption is due to BC while other sources o...
Long-term study of cloud condensation nuclei (CCN) activation of the atmospheric aerosol in Vienna [0.03%]
维也纳大气气溶胶云凝结核(CCN)活性的长期观测研究
