GPM GROUND VALIDATION DC-8 NAVIGATION AND HOUSEKEEPING DATA GCPEX

The GPM Ground Validation DC-8 Navigation and Housekeeping Data GCPEx dataset, which is composed of two types of files. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. National Suborbital Education and Research Center (NSERC) of the University of North Dakota (UND) provided geo-located housekeeping data containing attributes, such as altitude, pressure, air speed, and wind speed. The NASA DC-8 Navigation data in comma delimited IWG1 format were collected and utilized in-flight during the GCPEx mission and retrieved from the Real-Time Mission Monitor. Both file types are available for most of the dataset dates, however please note that there are a few dates where only the IWG1 formatted data is available.

GPM 地面验证 DC-8 导航与维护数据 GCPEx 数据集，由两种类型的文件构成。GCPEx 通过收集微物理特性、相关遥感观测以及降水雪的协调模型模拟，解决了 GPM 雪量检索算法的不足。北达科他大学（UND）的国家亚轨道教育与研究中心（NSERC）提供了包含如高度、气压、空速和风速等属性的地理定位维护数据。NASA 的 DC-8 导航数据以逗号分隔的 IWG1 格式收集，并在 GCPEx 任务期间空中采集，并从实时任务监控器中检索。这两种文件类型在数据集的大部分日期中均可用，但请注意，在少数日期中仅提供 IWG1 格式的数据。
