Single particle composition measured during the AGINSGP field experiment

Overview:

Size-resolved, single particle composition of ambient aerosol during the AGINSGP field campaign was measured by the miniSPLAT. The miniSPLAT is a single particle mass spectrometer that sizes particles using two scattering lasers, desorbs and ionizes them with a UV excimer (193 nm), and measures their composition using a bipolar time-of-flight analyzer (Zelenyuk et al. 2015). Data presented here are the time, vacuum aerodynamic diameter, and bi-polar spectrum (resolution of 1 m/z) for each particle.

Air was drawn into the GIF through custom aluminum stack inlets (6” inner diameter) attached vertically to the outer GIF wall and the GIF outside platform. A blower pulled air through the stacks at a velocity of 1 m/s. Aerosol instruments subsampled via wall ports, through either 3/8” or 1/4" copper lines, depending on sample flow of the instrument.

Single particle composition of ice crystal residuals was measured by the miniSPLAT during select sampling periods. These data are not reported here, but will be made available separately.
