Paper Abstract

Atmospheric phase stability was studied on two high elevation sites in the southwestern U.S. during the winter months. Results indicate that the phase stability is significantly better on the South Baldy site than on the Springerville site on long baselines at high frequency. On the South Baldy site high quality imaging is possible in a dynamic range greater than or equal to 100 at 230 GHz over half the time in the compact 70 m configuration. Phase stable observations at 230 GHz in the 3000 m array are possible only about 15 percent of the time, but self-calibration or fast external calibration make it possible to perform high frequency, long baseline observations for about 40 percent of the time.
