David Butterfield is a Senior Scientist in NPL’s Air Quality and Aerosol Metrology Group and is a technical expert on air quality instrumentation and data. David runs the UK’s Particulate Equivalence measurement site at NPL, where real-time particulate analysers are tested against the manual reference method. This enables them to demonstrate equivalence and hence be used in National Air Quality Networks.
He performs key roles in delivering National Air Pollution Networks for the UK Government (Automatic Urban and Rural Network, Heavy Metals Network, Black Carbon Network and the Particle Number and Speciation Networks). He is currently Data Ratification Manager for the London sites contained in the Automatic Urban and Rural Network.
David is a member of 3 CEN/TC264 standardisation groups developing ambient air measurement standards for particulate mass concentration and speciation.
