Aerosol Hygroscopicity Kappa Data Product Available for Evaluation
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 up moisture from the environment and is important for understanding the formation of cloud condensation nuclei (CCN). Users can now evaluate this VAP, called CCN…
