AOS: Humidified Tandem Differential Mobility Analyzer

The mosaoshtdmaM1.a1 datastream contains measurements of aerosol concentration and particle size distribution from the Aerosol Observing System (AOS) Humidified Tandem Differential Mobility Analyzer. This instrument, part of the AOS, measures aerosol properties to provide insights into aerosol behavior. The data were collected at Facility M1, which is part of MOSAIC (Drifting Observatory for the Study of Arctic Climate), a study conducted at the MOS site on the Arctic Ocean using a Mobile Facility (MOSAiC), between October 11, 2019, and October 1, 2020.
