GPM GROUND VALIDATION CONICAL SCANNING MILLIMETER-WAVE IMAGING RADIOMETER (COSMIR) IPHEx

The GPM Ground Validation Conical Scanning Millimeter-wave Imaging Radiometer (CoSMIR) IPHEx dataset consists of brightness temperatures from 9 channels as measured by the CoSMIR instrument onboard the NASA ER-2 aircraft during the Global Precipitation Mission (GPM) Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign in North Carolina. The goal of IPHEx was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. CoSMIR is a conical and cross-track scanning radiometer with frequencies centered at 50.3, 52.8, 89.0, 165.5, 183.31 ±1, 183.31±3, and 183.31±7 GHz. Data files are available from May 7, 2014 through June 14, 2014 in ASCII format, with browse images available in the postscript format.

GPM 地面验证锥形扫描毫米波成像辐射计（CoSMIR）IPHEx 数据集包含由 NASA ER-2 飞机上搭载的 CoSMIR 仪器在北卡罗来纳州进行的全球降水任务（GPM）综合降水和水文学实验（IPHEx）野外考察期间测量的9个通道的亮度温度。IPHEx 的目标在于评估卫星降水测量的准确性，并利用所收集的数据为该地区的流域水文学模型提供支持。CoSMIR 是一种锥形和交叉扫描的辐射计，其工作频率集中在 50.3、52.8、89.0、165.5、183.31 ±1、183.31±3 和 183.31±7 GHz。数据文件以 ASCII 格式提供，时间跨度为 2014 年 5 月 7 日至 2014 年 6 月 14 日，同时提供可浏览图像，格式为 PostScript。
