4/28 2004 13:40-18:00:  Check the accuracy of rain gauge. Precipitation data is not real.   By T. Koshida


5/25 2004 11:00-11:10: Change the program of data logger and tested rain gauge. Precipitation is not real.

Precipitation data from rain gauge before 5/25 2004 is quite smaller than real. Please look the data (Yotsuya-Taiyo-keiki-rain.txt) of rain gauge obtained at Taiyo-Keiki Co.,  Yotsuya in Tokyo where is about 5km south-west of IIS, instead of our data. By S. Miyazaki
