Lasers seem to end after a few hundred meters because of the planetary boundary layer. According to this this is because of the effects of particles that exist because of air interaction with the particles on the ground. However, what the article fails to explain is when the PBL is at its thickest. Does anyone know of when the PBL is thick to make the longest apparent beams?
