北半球湖冰厚度数据集（1992-2019，2071-2099）

本数据集包含：（1）基于测高卫星提取的北半球16个大型湖泊水库冰厚数据，时间跨度为1992-2019年，时间分辨率10天，文件名为Altimetric LIT for 16 large lakes.xlsx；（2）基于遥感湖冰模型的北半球1,313个面积50km^2以上湖泊的逐日湖冰厚度和湖泊表面积雪深度数据，时间跨度为2003-2018年，文件格式为nc格式；（3）未来湖冰厚度变化的预测情况，时间跨度2071-2099年，文件为table S1.xlsx；（4）一个用于查找湖泊的对照表，包含湖泊ID，名称，地理坐标和面积等信息。本数据集可以为全球湖冰和湖面积雪研究提供基础信息，便于深入理解在变化环境下湖冰的演变规律及其对湖泊生态环境和区域社会经济的影响。

This dataset includes the following components:
(1) 16 sets of lake ice thickness (LIT) data for large lakes and reservoirs in the Northern Hemisphere extracted from altimetric satellites, spanning the period from 1992 to 2019 with a 10-day temporal resolution, stored in the file *Altimetric LIT for 16 large lakes.xlsx*;
(2) Daily lake ice thickness and snow depth over lake surface data for 1,313 lakes in the Northern Hemisphere with an area of ≥50 km², derived from remote sensing lake ice models, covering the period from 2003 to 2018, saved in netCDF (.nc) format;
(3) Projections of future lake ice thickness changes, spanning the period from 2071 to 2099, stored in the file *table S1.xlsx*;
(4) A lake lookup table containing basic information such as lake ID, lake name, geographic coordinates, and lake area.

This dataset provides fundamental data for global lake ice and lake snow cover research, facilitating in-depth understanding of the evolution patterns of lake ice under changing environmental conditions, as well as its impacts on lake ecological environments and regional socio-economic development.
