And when modeling their behavior, they found that these pollution - modified particles have a large influence on cloud properties via ice crystal number concentration and ice water content. (pnnl.gov)
Total number concentration was dominated by frequent new particle formation and particle growth events. (en.ilmatieteenlaitos.fi)
While large particles such as these do not contribute substantially to the particle number they do make a substantial contribution to particle mass, to number concentration of cloud condensation nuclei, and strongly affect radiative properties of the aerosol. (arm.gov)
