Paper Abstract

We have been taking weather data at the location of the Subaru Telescope since 1999. We have also obtained the environmental data on many points in the telescope enclosure and on the telescope structure. Based on those, we will report the statistics of weather data and environmental condition around the Subaru Telescope as well as correlations among them. The statistics of nighttime clear sky ratios at Subaru Telescope site is presented. We have been gathering seeing data since the First Light of the Subaru Telescope in 1999, and we found a clear seasonal variation of the seeing size defined by FWHM method. A strong correlation between seeing sizes and wind velocities/directions is reported.
