Abstract

An instrument having a logarithmic response is described that continuously measures rates of rainfall over the range 0.3–350 mm h−1 by determining the electrical power required to evaporate the water as it arrives on an exposed sensor. Laboratory calibration experiments illustrate characteristics of the instrument, and field tests show agreement with a standard tipping-bucket raingage.
