The Millimeter Array (MMA) is proposed to operate on baselines of up to 3 km at frequencies up to 350 GHz. Since no operating interferometer can indicate the expected phase stability on such baselines on high, dry sites, NRAO has undertaken a site survey, measuring the opacity and estimating the phase stability on baselines ranging from about 100 m to 5 km with a tipping radiometer. Radiometers have sampled the atmospheres at South Baldy, NM, and Springerville, AZ, and NRAO has recently started taking data at the 12,200 foot VLBA site on Mauna Kea.
