Abstract

Cluster Analysis as a Quality Control/Quality Assessment Method for Background Atmospheric Non-Methane Hydrocarbon Measurements A contribution to subproject TOR-2 L Haszpra\ K Radios^ and J Bartholy^ ' Institute for Atmospheric Physics, Hungarian Meteorological Servce, H-1675 Budapest, P. O. Box 39, Hungary * Department of Meteorology, Eotvos Lordnd University, H-1083 Budapest, Ludovika ter 2, Hungary Basic concept Reactive non-methane hydrocarbon (NMHC) species play a crucial role in tropospheric ozone formation. For modelling the ozone formation and spatial distribution, reliable and representative NMHC measurements are required. The paper presents a mathematical statistical method which helps the quality control/quality assessment of the non-methane hydrocarbon data. Each natural or anthropogenic NMHC source has its own, specific hydrocarbo
