GPM Ground Validation NCAR Particle Probes IPHEx

The GPM Ground Validation NCAR Particle Probes IPHEx dataset consists of Ice Water Content (IWC), particle number concentration normalized by bin width, and total particle number concentration data that were collected from three particle probes onboard the University of North Dakota (UND) Citation II aircraft during the Global Precipitation Mission (GPM) Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx). These instruments include the PMS Two-Dimensional Cloud probe (2D-C), the SPEC Two-Dimensional Stereo probe (2D-S), and the SPEC High Volume Precipitation Spectrometer version 3 (HVPS-3). The IPHEx campaign took place in North Carolina with the goal of evaluating the accuracy of satellite precipitation measurements and using the collected data for hydrology models in the region. The campaign’s intense study period occurred from May 1 through June 15, 2014. All instruments are two-dimensional optical array probes which record images of particles that travel through the sampling area. The data files are available from May 9 through June 12, 2014 in ASCII format using the NASA Ames format specification. Browse images of instrument array 5-sec measurements are available in PNG format.

该GPM地面验证项目之NCAR粒子探测器IPHEx数据集由冰水含量（IWC）、按分箱宽度归一化的粒子数浓度以及总粒子数浓度数据组成，这些数据是在全球降水测量任务（GPM）地面验证综合降水与水文实验（IPHEx）期间，由北达科他大学（UND）Citation II飞机上的三个粒子探测器收集所得。这些仪器包括PMS二维云探测器（2D-C）、SPEC二维立体探测器（2D-S）以及SPEC高量程降水光谱仪第3版（HVPS-3）。IPHEx活动在北卡罗来纳州举行，旨在评估卫星降水测量的准确性，并利用所收集的数据对该地区的水文模型进行研究。该活动的密集研究期从2014年5月1日至6月15日。所有仪器均为二维光学阵列探测器，记录通过采样区域的粒子图像。数据文件以ASCII格式、遵循NASA艾姆斯格式规范，从2014年5月9日至6月12日可用。5秒测量值的仪器阵列浏览图像以PNG格式提供。
