Both recent and some older field measurements reveal condensation nucleus concentrations which attain local maxima within clouds. Model calculations are presented which suggest that, if the enhanced actinic radiation flux in clouds is taken into account, homogeneous, bimolecular nucleation within clouds is a viable mechanism for production of such particles.
