Bin schemes

Definition

Bin schemes are methods used to categorize and group particles or cloud microphysical variables into specific size ranges or bins, facilitating the study of cloud microphysics and precipitation processes. By organizing data into discrete bins, researchers can analyze the distribution of particle sizes, concentrations, and other properties, providing insights into cloud formation, development, and behavior.
