Cloud Particle Probe Microphysics

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.

本数据集包含来自NASA DC-8飞机上安装的两个翼载仪器——DMT降水成像探头（PIP）和SPEC二维立体探头（2D-S）——所获取的云粒子尺寸分布（PSD）和质量-尺寸分布（MSD）。数据采集于2022年7月8日至30日举行的“高冰水含量”（HIWC）野外考察活动，考察地点位于佛罗里达州的杰克逊维尔。研究飞行主要在墨西哥湾、大西洋和加勒比海进行，聚焦于典型喷气式飞机巡航高度上的高冰水含量区域。此外，多数飞行任务还包括一系列低空飞行段，以测量海洋 towering cumulus 云的气溶胶和微物理特征。此外，还包含了2022年9月30日的一次飞行数据，该次飞行并非HIWC 2022活动，而是对HIWC 2022的后续研究，采用相同的飞机进行。
