Seasonal variability in atmospheric black carbon at three stations in South-Asia
Filter-based optical measurements of black carbon in air, a constituent of soot, have been determined with a 528 nm light source during the period from 1 June 2005 to 31 May 2009 on samples taken at Godavari in Nepal, Sinhagad in India and Hanimaadhoo in the Maldives.In order to reduce systematic errors due to the light scattering of non-absorbing
