AOS: Humidified Tandem Differential Mobility Analyzer

The sgpaoshtdmaS01.a1 datastream contains measurements of aerosol concentration and particle size distribution from the Aerosol Observing System (AOS) Humidified Tandem Differential Mobility Analyzer. This instrument is part of the AOS and measures aerosol properties by analyzing particle size distribution under different humidity conditions. The data were collected at Facility S01 (Supplemental 1, Lamont, OK), which is located at the SGP site (Southern Great Plains), between March 28, 2016, and June 8, 2016.
