They explained these results by noting that at high nucleation rates, more nanometre - sized particles are competing for condensable gases to grow to CCN sizes.
Consequently, each particle grows more slowly than they would otherwise do in a situation with lower nucleation rates.
Ions increase the nucleation rate by an additional factor of between two and more than ten at ground - level galactic - cosmic - ray intensities, provided that the nucleation rate lies below the limiting ion - pair production rate.
They find that atmospherically relevant ammonia mixing ratios of 100 parts per trillion by volume increase the nucleation rate of sulphuric acid particles by more than a factor of 100 to 1,000.
We find that atmospherically relevant ammonia mixing ratios of 100 parts per trillion by volume, or less, increase the nucleation rate of sulphuric acid particles more than 100 — 1,000-fold.
