The Differential Aerosol Sizing and Hygroscopicity Spectrometer Probe (DASH-SP) is an in situ airborne spectrometer developed by Brechtel Manufacturing, Inc. It uses differential mobility analysis (DMA) with multiple humidification and sizing modules to measure aerosol optical size and hygroscopic growth factors. The probe can provide faster time resolution measurements compared to other hygroscopicity techniques. DASH-SP can measure aerosol particles in the size range of 0.1–1.0 μm and operates at the 532 nm wavelength.
