Aerosol Properties & Processes: Instruments

Spectrometers for Optical Aerosol Properties (SOAP)

Spectrometers for Optical Aerosol Properties (SOAP) is a compact, low maintenance instrument that measures aerosol extinction and absorption at 532 nm. Extinction is measured by cavity ringdown spectroscopy and absorption by photoacoustic spectroscopy.
