Accumulation rain gauge
From Glossary of Meteorology
accumulation rain gauge[edit | edit source]
(Also called accumulative rain gauge.) A class of rain gauges in which the precipitation is accumulated over time.
The depth of accumulated precipitation can be determined by the level of a float, by weighing, or by manual direct measurement of water depth. For long-term, unattended operation a known amount of liquid that prevents evaporation is placed in the collection container.
