Description
ARM currently fields 5 Aerosol Observing Systems (AOS); 3 associated with Mobile Facilities and 2 at Fixed Sites plus a 6th unit, the Mobile Aerosol Observing System (MAOS) available for deployment alone or with other systems and providing space for advanced ARM capabilities. These systems contain a baseline suite of instruments providing in situ microphysical, compositional and optical properties along with associated precursor and local meteorological measurements. As recommended by ARM workshops and the Aerosol Measurement Science Group (AMSG), multiple activities will be undertaken in 2018 to enhance the breadth, utility and availability of these measurements. Major activities are expected to include: implementation of a sample drying system prior to optical measurements, analysis of the ENA site representativeness, determining replacement filter media for optical absorbance measurements, conversion of the MAOS A/C units into the AMF1 AOS and a standalone MAOS, and advancing HSRL and Raman Lidar data products to extract vertically resolved aerosol absorbance coefficients. Other supporting activities will include: producing a comparable size distribution product across 4 instruments and ~104 range in diameter, deploying an ozone analyzer at SGP, assessment of a kappa data product from the HTDMA, enhanced user data products for both types of ARM ACSMs, and enhancements to user accessibility of ARM aerosol data.
