Nystuen9818726Building on prior development and laboratory tests of acoustic rainsensing technology, field-deployable acoustic rain gages will beconstructed and tested under operational conditions. The acousticgages will be mounted on two TAO moorings in the tropical Pacific.Data from the acoustic instruments will be compared with data fromcapacitance rain gages located on the same moorings and with rainfallestimates deduced from satellite observations. The rainfall observations will be combined with upper ocean salinity measurementsfrom the moorings to examine the fresh water budget of the upper ocean.

在声学雨感技术的先前开发和实验室测试的基础上，将建造现场可部署的声学雨计，并在操作条件下进行测试。声学仪器将安装在热带太平洋的两个TAO系泊处。来自声学仪器的数据将与位于相同系泊处的电容雨量计的数据以及从卫星观测推断的降雨量进行比较。降雨观测将与系泊处的上层海洋盐度测量相结合，以检查上层海洋的淡水收支。
