CLOud Processing of regional Air Pollution advecting over land and sea (CLOPAP) was a NERC Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00147 - Duration 2002 - 2005) led by Prof. Tom Choularton, University of Manchester. CLOPAP was an aircraft measurement campaign using the FAAM BAe-146-301 aircraft to make measurements of the ageing of the London plume in the cloudy boundary layer. Measurements were made of the evolution of trace gases, aerosol and cloud properties. These were supported by modelling studies. The flights were scheduled to take place between March and September 2005. With an additional flight in September 2006. The dataset includes data from - core FAAM instruments. - from non-core instruments fitted for the campaign including the UMIST aerosol mass spectrometer, gas probes and particle physics instruments.
