A study on a validation of a new precipitation measuring method by using a droplet counting precipitation
Toshiro KUMAKURA
Tipping bucket precipitation gauges have been used in a conventional precipitation measuring in Japan,
which measure each 0.5 mm of the precipitation. We are able to employ a newly usable precipitation gauge,
called a droplet counting gauge. It can measure about each 0.005 mm as a water droplet detected by an optical active sensor.
Then we develop a new measuring method which uses dropping time interval.
This method has a merit of introducing the high measuring time resolution.
We carried out some observations with two precipitation gauge, the tipping bucket gauge and the droplet counting gauge, to validate the new method on the rain.
We found that the measuring results with the new method were about 1.06 times larger than the result with the tipping gauge,
which was thought that these values had errors of formulation and observing locations of two gauges, and this relationship had fine correlation on the rain.
