Other Monitors

When planning any atmospheric precipitation measurement, contact the National Meteorological Institute or equivalent organization for expert assistance.

Various types of open containers and man-made natural surfaces are used to collect impurities deposited by atmospheric forces. Open containers are generally polyethylene, polypropylene, or glass funnels or cylinders. Various modified gauge types are designed for special purposes.

Precipitation intensity, volume, and duration data should be collected during qualified sample events, and for monitoring programs. Nonrecording gauges are used for measurement by most government hydrological and meteorological services. The ordinary rain gauge used for daily readings is a collector above a funnel leading to a receiver. Continuous registration has also been incorporated into rain gauges. Precipitation recorders in general use are the weighing, tipping-bucket, or float type. If the standard rain gauge is sited in the wind direction, it should be surrounded by an 0.4 m-high screen. A wind shield consisting of a frame of hanging strips is placed within 1 m of the recorder.
