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（cloud particle size distributions, PSDs）与质量尺度分布（mass-size distributions, MSDs），数据源自搭载于NASA DC-8型飞机机翼的两台探测仪器：DMT降水成像探针（DMT Precipitation Imaging Probe, PIP）以及SPEC二维立体探针（SPEC Two-Dimensional Stereo probe, 2D-S）。数据采集于2022年7月8日至30日开展的高冰水含量（High Ice Water Content, HIWC）外场试验，试验基地设于佛罗里达州杰克逊维尔市。研究飞行航线覆盖墨西哥湾、大西洋及加勒比海区域，主要针对典型喷气式客机巡航高度下的高冰水含量区域开展观测。此外，多数飞行任务包含多段低空飞行航段，用于测量海洋性浓积云的气溶胶与微物理廓线。本数据集还包含2022年9月30日一次飞行任务的额外数据文件，该任务并非2022年HIWC试验的飞行场次，而是使用同一架飞机开展的HIWC 2022后续观测任务。
