HIWC_2022: Cloud Particle Probe Microphysics. Version 1.0

This dataset consists of cloud particle size distributions (PSDs) and mass-size distributions (MSDs) derived from two wing-mounted instruments installed on the NASA DC-8 aircraft: the DMT Precipitation Imaging Probe (PIP), and the SPEC Two-Dimensional Stereo probe (2D-S). The data were collected during the High Ice Water Content (HIWC) field campaign from July 8-30, 2022, based out of Jacksonville, Florida. Research flights were conducted over the Gulf of Mexico, the Atlantic Ocean, and the Caribbean Sea, primarily focusing on areas of high ice water content at typical jet aircraft cruise altitudes. Additionally, most flights included a series of low-level flight legs to measure aerosol and microphysical profiles of oceanic towering cumulus clouds. There are additional data files from a flight on September 30, 2022. This was not a HIWC 2022 flight, but was a follow-on to HIWC 2022 using the same aircraft.

本数据集包含云粒子尺度分布（PSDs）与质量尺度分布（MSDs），数据来源于安装于NASA DC-8型飞机机翼上的两款仪器：DMT降水成像探针（PIP）与SPEC二维立体探针（2D-S）。
该数据采集于2022年7月8日至30日在佛罗里达州杰克逊维尔开展的高冰水含量（HIWC）野外试验期间。科研飞行区域覆盖墨西哥湾、大西洋与加勒比海，核心研究对象为典型喷气式客机巡航高度下的高冰水含量区域。
此外，多数飞行任务包含多段低空航段，用于测量海洋性浓积云的气溶胶与微物理廓线。
另有2022年9月30日一次飞行的附加数据文件，此次飞行并非2022年HIWC试验的常规飞行，而是使用同款飞机开展的HIWC 2022后续任务。
