Abstract

The Compact Lightweight Aerosol Spectrometer Probe (CLASP) is an optical particle spectrometer capable of measuring size-resolved particle concentrations in 16 user-defined size bins spanning diameters in the range 0.24 < D < 18.5 μm at a rate of 10 Hz. The combination of its compact nature and lightweight and robust build allows for deployment in environments and locations where the use of the larger, heavier, more traditional instrumentation would prove awkward or impossible. The high temporal resolution means it is particularly suited to direct measurements of aerosol fluxes via the eddy covariance technique. CLASP has been through an extended evolutionary development. This has resulted in an instrument whose performance characteristics are well established.
