GPM GROUND VALIDATION ADVANCED MICROWAVE PRECIPITATION RADIOMETER (AMPR) IPHEX V2

The GPM Ground Validation Advanced Microwave Precipitation Radiometer (AMPR) IPHEx dataset was acquired by the AMPR instrument flown aboard the high altitude ER-2 aircraft during the IPHEx field campaign in North Carolina from May 1, 2014 through June 14, 2014. The goal of IPHEx was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. These files include the Level 2B calibrated and georeferenced brightness temperature for the four AMPR-observed frequencies (10, 19, 37, 85 GHz). These data are archived in a netCDF-4 format that contains the calibrated brightness temperatures in addition to ER-2 aircraft navigation and instrument scene georectification variables. Corresponding browse imagery are also available in JPG format. A set of Python software has been developed for reading, plotting, and providing some additional analysis capabilities.

GPM 地面验证高级微波降水辐射计（AMPR）IPHEx 数据集，系由搭载于高空 ER-2 飞机上的 AMPR 仪器在 2014 年 5 月 1 日至 2014 年 6 月 14 日于北卡罗来纳州进行的 IPHEx 场地实验期间所采集。IPHEx 的目标在于评估卫星降水测量的精确度，并利用所收集的数据对区域内的水文模型进行应用。这些文件包含了四个 AMPR 观测频率（10、19、37、85 GHz）的二级 B 级校准及地理定位亮度温度。这些数据以 netCDF-4 格式存档，其中包含校准后的亮度温度，以及 ER-2 飞机导航和仪器场景地理校正变量。同时，还提供了相应的 JPG 格式浏览图像。一套 Python 软件也已开发，用于读取、绘图以及提供一些额外的分析功能。
