ClearSkyRatio_GarOmaKarasuSubaruOAO_9_2
Comparison of Clear Sky Ratio at Karasu, Oma, Ali in Tibet, OAO (Japan), Subaru Telescope/Hawaii Haleakala/Maui/Hawaii, and Chajnantor/Chile

InstrumentLayout
    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 Simulation in west Tibet using WRF and JMA-NHM]
   (click here to refer to Weather Simulation Page (need UID/PWD))
  • WRF (Weather Research and Forecasting )
    WRF has been used to simulate weather environments around Ali By Dr. Wang/NAOC. Simulated data have been transferred to U-Hiroshima and anaslysed at NAOJ.

    Surface Wind Speed map on 2010-01-01, simulted w/WRF by Dr.Wang.

    Surface Wind Speed map and Verticval distribution on 2010-01-01, simulted w/WRF by Dr.Wang.

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