Abstract

The purpose of this study is to estimate the impact of rainfall measurement according to the installation
conditions of rain gauges: windbreak, grass mat, installation elevation or obstacle. Rain gauges were installed
by the standards of Korea Meteorological Administration(KMA), and the rainfall measurement was conducted
daily unit during two years(2007~2008). In conclusion, observed error of rain gauge did not affect whether
windbreak was installed or not. If there is the obstacle around rain gauge, average error rate was increased
about 3.3%: (2007year-2.49%, 2008year-4.10%). If rain gauge is located in a high place, average error rate
was increased about 4.89%. Additionally, the observed error of rain gauge according to the wind speed has
a positive correlation with obstacle and installation elevation and has a negative correlation with windbreak
and has no affection with grass mat.
