Excess ground ice profiles from Sentinel 1

Maps of excess ice content profiles were estimated from Sentinel-1 subsidence observations. Results for three study regions in Alaska are included:

Happy Valley, Brooks Foothills

Ice Cut, Brooks Foothills

Kivalina, Northwestern Alaska

The results for each region are contained in the corresponding .zip file. The subfolders correspond to the different years. The content of each subfolder are as follows:

meta.txt: human-readable metadata: geolocation information (rasterio affine transformation, projection, size of image, vertical grid [m])

e_mean.npy: array containing the posterior mean of the excess ground ice profiles e [-]

e_quantile.npy: array containing the 10th and 90th posterior percentile of the excess ground ice profiles e [-]

本数据集的过量冰含量剖面分布图基于哨兵-1号（Sentinel-1）沉降观测数据估算得到，包含阿拉斯加3处研究区域的分析结果：
1. 布鲁克斯山麓快乐谷（Happy Valley, Brooks Foothills）
2. 布鲁克斯山麓冰蚀区（Ice Cut, Brooks Foothills）
3. 阿拉斯加西北部基瓦利纳（Kivalina, Northwestern Alaska）

各区域的分析结果存储于对应的.zip压缩文件中，其子文件夹按不同年份划分。每个子文件夹内包含以下文件：
- meta.txt：可读元数据文件，包含地理定位信息（rasterio仿射变换参数、投影信息、图像尺寸以及垂直网格[单位：m]）
- e_mean.npy：存储过量地下冰剖面e的后验均值的数组，无量纲[-]
- e_quantile.npy：存储过量地下冰剖面e的后验10分位数与90分位数的数组，无量纲[-]
