Droplet Aerosol Analyser (DAA) for Measuring Ambient Cloud and Fog Droplets

DESCRIPTION

The Droplet Aerosol Analyser (DAA) is an advanced instrument designed to measure the number size distribution of ambient cloud and fog droplets, as well as interstitial particles under ambient conditions. It also provides insights into the number size distribution of dry residual particles and the correlation between ambient diameter and dry diameter on a single droplet or particle basis. The DAA has been effectively employed in significant studies, including results from Great Dun Fell, England, in 1995, showcasing its capability to generate detailed 3-dimensional data sets.
