Outline of Final Research Achievements

The high plateaus in west Tibet may provide promising sites for a part of global astronomical observation network. We have been conducting to search for good sites to monitor at Gar (Tibet) since 2010 after previous monitoring at Karasu (Xinjiang Uighur) and Oma (Tibet). Weather characteristics at Gar shows its high clear-sky ratios, comparable to Mauna Kea. A wind problem at Gar has been revealed in winter that higher wind speeds over 20m/sec occur frequently even though sky is clear.
To find more calm site both with high clear-sky ratios and mild wind speed, we have searched for another site, ZoZo Hill, near Gar. To clarify their weather characteristics, we have conducted numerical simulations at Gar and ZoZo Hill using Japan Meteorological Agency Non-Hydrostatic Model. ZoZo Hill shows nearly half wind speed than at Gar.
We hopefully should continue to monitor Gar site to clarify weather characteristics through a whole year and start site monitoring at ZoZo Hill in near future.
