Abstract

The characterization of seeing degradation induced by near-ground microturbulence is useful not only for selecting the optimum astronomical observatory site, but also for determining the suitable height above the ground for telescope installation. The near-ground contribution to seeing can be established by measurements of stellar image motion, and microthermal activity as a function of altitude. These techniques are applied to several superior sites known to have seeing < 1 arcsecond.
