(Notes: Gar is recoginized as Ali, please)

Site map of Site Monitoring in west China, starting in 2007 to the present.
Gar (5036m) and ZoZo Hill(4619m),
possibly better sites in Ali area, Tibet
Comparison of Clear Sky Ratio at Karasu, Oma, Gar/Ali in Tibet, OAO (Japan), Subaru Telescope/Hawaii Haleakala/Maui/Hawaii, and Chajnantor/Chile

( click here to D/L in pdf )
    When avilability on usage of telescope is limited under wind speed less than 14m/sec, the ratio of ClearSky is down to nearly the same level at OAO (Okayama, Japan), terribly!
Weather monitoring at Oma during Jan 2009 to Jun 2009.
Weather monitoring at Gar during Jan 2013 to Jun 2013.

Vertical Wind Speed Profile, simulated w/WRF at Gar and ZoZo Hill


Vertical Wind Speed profiles around midnight are shown at site locations A1, B1 at Gar, and ZoZo Hill added with high peaks #1 and #2 near ZoZo Hill.

Wind speed profiles around midnight in Jan,2010, in which high speeds are shown in upper atmosphere layers.

  • WRF (Weather Research and Forecasting )
    WRF has been used to simulate weather environments around Gar By Dr. Wang/NAOC. Simulated data have been transferred to U-Hiroshima and anaslysed at NAOJ.

  • JMA-NHM (Japan Meteorological Agency NonHydrostatic Model)
    Dr. Naoe has conducted to simulate weather environments around Gar and summarized the results.
