The Olympic Mountains Experiment (OLYMPEX) is a ground validation field campaign designed to verify and validate satellite measurement of precipitation from the constellation of satellites known as the Global Precipitation Measurement (GPM). The primary goal of OLYMPEX is to validate rain and snow measurements in midlatitude frontal systems moving from ocean to coast to mountains and to determine how remotely sensed measurements of precipitation by GPM can be applied to a range of hydrologic, weather forecasting and climate data. OLYMPEX will have a wide variety of ground instrumentation, and several radars and aircraft monitoring oceanic storm systems as they approach and traverse the Peninsula and the Olympic Mountains. The intensive observing period will be from November 2015 through February 2016.
