HISCALE-SMPS

Holistic Interactions of Shallow Clouds, Aerosols, and Land-Ecosystems (HI-SCALE):Scanning Mobility Particle Sizer (SMPS)

21 April 2016 - 23 September 2016

Lead Scientist: Jerome Fast

Observatory: SGP (Southern Great Plains)

An SMPS instrument was requested to be deployed at the SGP Central Facility so that it can be used to calibrate EMSL's aerosol mass spectrometer (AMS) that will be deployed as part of HI-SCALE. We expect that 4-5 calibrations (about once per week) will need to be performed during both the spring and late summer HI-SCALE deployments. The calibrations need to be performed with the instruments side by side and since the AMS will be housed in the Guest Instrumentation Facility, it is desirable to have the SMPS available in the GIF for the calibrations. An aerosol particle sizer (APS) will also be at the SGP and measuring data during HI-SCALE. This instrument is designed to measure the size-resolved concentrations of coarser particles; therefore, another instrument is needed to sample smaller particles. It would be desirable to deploy the UHSAS for that purpose or to make sure some instrument is operating to measure size-resolved concentrations of smaller particles.
