Effect of the Summer Monsoon on Aerosols at Two Measurement Stations in Northern India ? Part 1: PM and BC Concentrations

Popis výsledku v původním jazyce

Particulate matter (PM) and equivalent black carbon (BCe) concentrations were measured at two locations in northern India during 2006?2010. The average monsoon time concentrations were decreased by 55?70 % compared to the pre-monsoon average concentrations at both stations, decreasing as a function of the total local rainfall during the monsoon season. In addition to loss processes, aerosol concentrations during the early monsoon were found to be affected by primary emissions, most likely from dust events from the Thar Desert. This resulted in elevated fractions of the coarse mode, PM2.5?10 at both stations. We also determined the characteristic transition times between the pre-monsoon, monsoon and post-monsoon. The shorter transition times in Mukteshwar were probably related to the more intense rains due to the mountain location, and the fact that the station was most of the time in the free troposphere.
