Instrumentation for Rainfall Sampling

Abstract

<p>An instrumentation package for sensing rainfall amount and intensity with fine time and space resolution is described. The package comprises a drop counter precipitation sensor, a microcomputer-based data acquisition system, and an intelligent data decoder. The accuracy of the precipitation sensor and the parameters that affect it are discussed. The reliability is reviewed and typical rainfall data are included. A comparison is made between the performance and accuracy of the new precipitation sensor and conventional tipping bucket raingauges. The merits and demerits of the new system are discussed.</p>
