    Title: " 中国気象衛星データから探る西チベットでの天文台サイト探査"
    Authors: 佐々木敏由紀, Toshiyuki Sasaki (NAOJ)
      An satellite weather data taken by Chinese weather sattelite FY2 are used to evaluate the weather conditions around the west Tibet by help of ground based sky-conditions during our monitoring at Ali. Rough estimate shows the site eastward from Ali looks better with good conditions in surrounded area.

● Report on Microthermal measurement at Karasu during Oct 26-28, 2007. ( pdf (1.4MB) ) Passworded
    [Abstract] Atmospheric turbulence is measured with microthermal sensors at 5 heights (36.15m, 19.15m, 10.15m, 6.25m and 4.15m) at Karasu during Oct 26 and 28, 2008. Microthermal measurements show that the surface turbulent layer affects below 19m high. Seeing sizes are estimated from microthermal measurements with an average of estimated seeing is 0.196 arcsec at ground level, larger than 0.1 arcsec observed at other observatory sites. Karasu site may be affected considerably with atmospheric turbulence triggered by mountain-lee-wave triggering mechanism.
● Report on analysis using satelliete database: FriOWL and CLAUS ( pdf (3.3MB) ) Passworded
    [Abstract] Using FriOWL and CLAUS weather database, China mainland is investigated to search for areas with good astronomical conditions. Five sites (Karsu, Oma, Hami, Xinglong, and Yunnan) are studied and compared; Oma area is relatively better in Tibet where diurnal variations of weather conditions should be investigated. Karasu shows not so good conditions. An area around Hami shows potentiality for good astronomical observations in China.
