[en] Inspection and repair of tower structure and lift, instrument calibration have been done. Wireless data transmission to MIPS(Meteorological Information Processing System) has been done after collection in the DAS where environmental assessment can be done by the developed simulation programs in both cases of normal operation and emergency. Wind direction, wind speed, temperature, humidity at 67m, 27m, and 10m height and temperature, humidity, atmospheric pressure, solar radiation, precipitation, and visibility at surface have been measured and analyzed with statistical methods. At the site, the prevailing wind directions were SW in spring and summer, NNW in winter season. The calm distributed 28.6% at 67m, 20.5% at 27m, 39.2% at 10m height. 9 tabs., 4 figs., 6 refs. (Author)
