Cloud Condensation Nuclei (CCN) Calculator

Introduction : This calculator calculates the number of nuclei of a certain radius size in a volume of air with a concentration of c. Cloud Condensation Nuclei or CCN are the basis of cloud formation. Dust or aerosol particles collect moisture from the air thus forming CCN. In this calculator, you have two input values:
  1. Constant dependent on the total concentration of particles (c)
  2. Particle radius (R) in micrometers (um)

The algorithm for the number density of the cloud condensation nuclei is:
