  • New Aerosol Hygroscopicity Kappa Data Available

    Sample CCNSMPSKAPPA plots from the Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign in Colorado show kappa values within critical diameter-supersaturation field space (top) and a time series of kappa (bottom) on March 15, 2022, at ARM’s Aerosol Observing System (AOS) site on Crested Butte Mountain. The CCN particle counter and SMPS operated as part…

  • New Aerosol Hygroscopicity Kappa Data Ready for Evaluation

    Sample CCNSMPSKAPPA plots from the Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign in Colorado show kappa values within critical diameter-supersaturation field space (top) and a time series of kappa (bottom) on March 15, 2022, at the Crested Butte Mountain Resort site.

  • New Aerosol Hygroscopicity Kappa Data Released for 3 ARM Sites

    Sample CCNSMPSKAPPA plots from the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign show kappa values within critical diameter-supersaturation field space, top, and a time series of kappa, bottom, on November 15, 2018. Hygroscopicity is the ability of a particle to take up moisture from the environment and is important for understanding the formation…

  • Aerosol Hygroscopicity Kappa Data Product Available for Evaluation

    Sample plots from ARM’s Southern Great Plains atmospheric observatory show kappa values within critical diameter-supersaturation field space, top, and a time series of kappa, bottom. A new value-added product (VAP) from the Atmospheric Radiation Measurement (ARM) user facility calculates the hygroscopic properties of measured aerosol particles. Hygroscopicity is the ability of a particle to take…
