Basic knowledge of Cloud Condensation Nuclei (CCN) is necessary to understand the nature of the difficulties in testing the CLAW hypothesis. Here is a supplementary explanation. Know that there are conditions under which microparticles can grow to cloud condensation nuclei.
Even normal marine chemistry and marine science do not go into this content. You need to know how aerosols condense and grow cohesively, and that there are conditions under which they become cloud condensation nuclei (cloud nuclei). If you know this, "you can talk about aerosol science and cloud science like you know it."
This is a condensation of condensible molecules and particle nucleation. The key is not to increase the number of atmospheric particles in mid-air particle nucleation.
There are fine particles that grow buzzing up to cloud particles, and there are fine particles that stop growing in the middle of the cloud. Know that the nature of the original fine particles (the amount of solute) is the determining factor.

【Particle size range classification】Aerosol particles with diameters of 0.01 μm or less are called nuclei mode, 0.1 μm or less are called coagulation mode, 0.1 to 1 μm are called accumulation mode, and 1 μm or more are called coarse mode.
The mechanism by which airborne particles are collected by the filter has been explained.
