基于多源卫星测高数据的青藏高原湖泊水位（2010-2020）

该数据集为基于多源卫星测高数据的青藏高原湖泊水位（2010-2020）。该数据集包括4种：CryoSat-2 L1B Baseline D 提取的244个湖泊水位 （2010-2020年）；ICESat-2 ATL13 提取的356个湖泊水位 （2018-2020年）；Sentinel-3A SRAL L2 提取的125个湖泊水位 （2016-2020年）；Sentinel-3B SRAL L2 提取120个湖泊的水位 （2018-2020年）。数据包括日期、十进制日期、水位、标准差以及每个湖泊的地理位置。
数据集文件命名：位于data文件夹下的湖泊水位数据以文本格式存储，文件的名称为“ID.txt”，其中ID代表湖泊的ID号，比如1.txt就代表这个文件描述湖泊ID 为1的湖泊水位；位于location文件夹下的数据表示每个湖泊的位置，文件名中的ID号可以在字段ID中对应。

This dataset provides lake water level records (2010–2020) for lakes on the Qinghai-Tibet Plateau, generated using multi-source satellite altimetry data. It includes four subsets of data:
1. 244 lake water level records (2010–2020) extracted from CryoSat-2 L1B Baseline D;
2. 356 lake water level records (2018–2020) extracted from ICESat-2 ATL13;
3. 125 lake water level records (2016–2020) extracted from Sentinel-3A SRAL L2;
4. 120 lake water level records (2018–2020) extracted from Sentinel-3B SRAL L2.
The dataset contains the following attributes for each lake: date, decimal date, water level, standard deviation, and geographic location.
Regarding file naming: Lake water level data are stored in plain text format under the `data` folder, with filenames in the format "ID.txt", where "ID" represents the unique ID number of the lake. For example, 1.txt describes the water level data for the lake with ID 1. The data stored under the `location` folder contain the geographic locations of each lake, and the ID number in the filename corresponds to the ID field in the dataset.
