SBU Ceilometers IMPACTS

The SBU Ceilometers IMPACTS dataset includes ceilometer cloud height measurements collected by the Vaisala CL51, Vaisala CT25K, and Lufft Ceilometer CHM 15k ceilometers operated by the State University of New York (SUNY) Stony Brook University. These data were collected during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign, a three-year sequence of winter season deployments conducted to study snowstorms over the U.S. Atlantic coast. IMPACTS aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The ceilometer dataset files are available from January 1, 2020, through March 2, 2023, in netCDF-3 and netCDF-4 formats.

SBU Ceilometers IMPACTS 数据集收录了纽约州立大学石溪分校（SUNY Stony Brook University）所运营的 Vaisala CL51、Vaisala CT25K 以及 Lufft Ceilometer CHM 15k 云高计所采集的云层高度测量数据。这些数据是在针对大西洋沿岸威胁性暴风雪的微物理和降水调查（IMPACTS）野外考察活动中收集的，该活动为为期三年的冬季部署序列，旨在研究美国大西洋沿岸的暴风雪。IMPACTS 的目标在于：（1）提供对理解雪带形成、组织及演化的关键性观测；（2）探究雪粒子微物理特性及其可能的生长机制在雪带之间的变化；（3）提升降雪遥感解释和建模能力，以显著推进预测能力的提升。该云高计数据集文件以 netCDF-3 和 netCDF-4 格式提供，时间跨度从 2020 年 1 月 1 日至 2023 年 3 月 2 日。
