Aerosol number concentration

PM is measured using the optical particle counter (OPC GRIMM 190), which measures the size distributions for particle with diameters greater than 0.25 up to 32µm by means of 90° laser light scattering. The Aerosol number concentration measurement is a subset of core variables that are recommended by the GAW Scientific Advisory Group on Aerosols for long-term measurements in the global network.

Lineage
Measurement data from March 2006 are recorded at the station Nepal Climate Observatory at Pyramid in the Himalaya (Nepal, 5059 m asl) are part of ABC-DISC database, maintained by UNEP (United Nations Environmental Programme). Optical Particle Counter (OPC, GRIMM 190) determining the aerosol size distribution for particle diameters from 0.25 up to 32 µm in 31 channels, with an accuracy of 2%, on concentrations. Coarse particles, with diameters larger than 1 µm are considered as a proxy of dust aerosol. From the OPC measurements the mass concentrations of PM1 were derived. Due to instrument failure, the measurements were interrupted on 4 December 2007 and resumed on 5 February 2008.
