Lake Ulansu Ice Phenology Data (1941–2023)

This dataset contains the ice phenology data of Lake Ulansu from 1941 to 2023, derived using passive microwave data for the period 1979–2023 and extended back to 1941 through a random forest model. The data provides insights into the freeze-up start, break-up end, and ice cover duration, contributing to the understanding of ice phenology in the context of climate change.

本数据集涵盖1941年至2023年乌梁素海（Lake Ulansu）的冰物候（ice phenology）数据。其中1979年至2023年时段的数据通过被动微波数据（passive microwave data）反演得到，并借助随机森林模型（random forest model）将数据序列回溯延伸至1941年。该数据集包含封冻起始日期、融冰结束日期与冰盖持续时长等核心信息，可为气候变化背景下的湖泊冰物候研究提供重要支撑。
