This dataset contains single particle soot photometer measurements made at the IAP-Beijing site during the summer and winter APHH-Beijing campaign for the Atmospheric Pollution & Human Health in a Chinese Megacity (APHH) programme.

Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Meteorological Particle Sensor between 2004 and 2007. During this time the particle sensor was at Sparsholt College, Hampshire, after which it was re-located to Chilbolton. The dataset contains measurements of the size of individual particulates including rain, snow, and hail, as well as estimates of drizzle, total rainfall and liquid water content.
