GPM Ground Validation Advanced Microwave Precipitation Radiometer (AMPR) OLYMPEX V1

The GPM Ground Validation Advanced Microwave Precipitation Radiometer (AMPR) OLYMPEX dataset was collected by the AMPR instrument flown on the high altitude ER-2 research aircraft from November 9 - December 15, 2015, during the Olympic Mountains Experiment (OLYMPEX) field campaign conducted at Washington State’s Olympic Peninsula. AMPR is an airborne passive microwave radiometer from which cloud, precipitation, water vapor, wind speed and wind direction can be obtained using advanced algorithms with the 10.7, 19.35, 37.1, and 85.5 GHz microwave frequency brightness temperatures measured by AMPR. The primary goal of OLYMPEX was to validate rain and snow measurements in midlatitude frontal systems moving from ocean to coast to mountains. AMPR data at the Global Hydrology Resource Center (GHRC) DAAC include netCDF format data files of brightness temperature and PNG browse files of Quality Control Flags and Brightness Temperatures.

该GPM地面验证高级微波降水辐射计（AMPR）OLYMPEX数据集由搭载于高空ER-2研究飞机上的AMPR仪器于2015年11月9日至12月15日收集，该数据集是在华盛顿州奥林匹克半岛进行的奥林匹克山脉实验（OLYMPEX）野外考察期间获得的。AMPR是一种机载被动微波辐射计，通过采用先进的算法，可以从中获取云、降水、水汽、风速和风向信息，这些信息是通过AMPR测量的10.7、19.35、37.1和85.5 GHz微波频率的亮度温度得到的。OLYMPEX的主要目标是验证从中纬度海洋向海岸和山脉移动的锋面系统中的雨和雪的测量。全球水文学资源中心（GHRC）的DAAC中包含的AMPR数据为亮度温度的netCDF格式数据文件以及质量控制标志和亮度温度的PNG浏览文件。
