Laos is a longlocked country, many mountains and rivers are located in this country. Therefore, the humidity is high, and there are plenty of precipitations. JICA installed rain gauge in each place in order to measure river flow of Laos. As the result, in Pak Song of the southern district, the region where annual precipitation over 4000mm. An annual precipitation which exceeds 4000mm is observed in equatorial region. At the monthly precipitation of Pak Song(measurement point : Se Done)measured about 1400mm in July 1999. Thie value is equal to annual precipitation of Tokyo, Japan. We obtaine regional characteristics of satellite signals reception non-working rate by rain attenuation. In Laos, it was clarified that the heavy rain region was large.
