ABSTRACT
A partial solar eclipse occurred in South Korea on 22 July 2009. It started at 09:30 a.m. and lasted until 12:14 LST with coverage of between 76.8% and 93.1% of the sun. The observed atmospheric effects of the eclipse are presented. It was found that from the onset of the eclipse, solar radiation was reduced by as much as 88.1 approximately 89.9% at the present research centre. Also, during the eclipse, air temperature decreased slightly or remained almost unchanged. After the eclipse, however, it rose by 2.5 to 4.5 degrees C at observed stations. Meanwhile, relative humidity increased and wind speeds were lowered by the eclipse. Ground-level ozone was observed to decrease during the event.

Mentions: A meteorological map of 22 July 2009 is included in Fig. 2. Korea was under the influence of an anticyclone and fair weather with variable low clouds prevailed during the period of the partial eclipse. There were more clouds in southern Korea than in central Korea (cloud amount in Table 1). This was related to a stationary and rainy front situated along the line from Shanghai, China to the south of Japan. Likewise, there were considerable amounts of clouds over the Korea South Sea (Fig. 3).Fig. 2
