To investigate new particle formation (NPF) events in urban and forest environments, number size distributions of ultrafine particles were measured at an urban site and a deciduous forest site in Sapporo, Northern Japan, during the summers of 2011 and 2010, respectively. The burst of nucleation mode particles at the urban site typically started in the morning (07:00-11:30 local time, LT) with simultaneous increases in SO 2 and O 3 concentrations and the UV index under clear (sunny) weather
