I got the suggestion from Matt, and try to achieve it. And I get the technic in a small Youtube tutorial about camera culling, which was created by Tim van Helsdingen
The idea is using a UVtexture node and get the camera distance by the projection mode. And then, use that to adjust your particle size with the VEX on the left.
Particle Floating
I adjust the value of my particle curve force and popwind force to get the results.
