Rain gauges: weather instruments tour
This plastic cylinder will hold 25 mm of rain water. If more than that amount of rain falls between observations, the overflow will be caught in the white outside container. The white container can be lifted off its mounting post to pour the contents into the cylinder. The excess rainfall can be measured--25 cm at a time--in this same cylinder to arrive at a total.
A second type, the tipping bucket rain gauge, can be used at either manned or automatic stations. It can be connected to send electronic impulses to either a chart recorder for people to look at or to a computer system for transmission as part of an automatic weather report. Although it looks much the same as the standard rain gauge, it's bigger and the mechanism inside is completely different. Let's cut one open and have a look inside!
