Kivalina subsidence observations

Updated on 2023-10-4 to correct scaling error. The original estimates were a factor of two too large. Corrected version. The original estimates (v1.0) were a factor of two too large due to a coding error. Thaw-season subsidence in [m] near Kivalina, Northwestern Alaska, derived from Sentinel-1 observations. For each year yyyy from 2017-2019: yyyy_de_dl.tif contains the early-mid-season (10 June - 10 August) and late-season (10 August - 10 September) subsidence estimated from the spline reconstruction yyyy_timeseries.tif contains the regularly sampled, unconstrained subsidence The dates are: 2017: ['20170604T173314', '20170616T173315', '20170628T173316', '20170710T173316', '20170722T173317', '20170803T173318', '20170815T173318', '20170827T173319', '20170908T173319']2018: ['20180611T173321', '20180623T173322', '20180717T173323', '20180729T173324', '20180810T173325', '20180822T173325', '20180903T173326']2019: ['20190606T173327', '20190618T173327', '20190630T173328', '20190712T173329', '20190724T173330', '20190805T173330', '20190817T173331', '20190829T173332', '20190910T173332']本数据集于2023年10月4日更新，以修正缩放误差。原始估算值偏大了一倍。 修正版本说明：因编码错误，原始（v1.0版）估算值偏大了一倍。 本数据集为基于哨兵-1（Sentinel-1）观测数据提取得到的阿拉斯加西北部基瓦利纳（Kivalina）附近区域的解冻季地面沉降量（单位：米）。 针对2017至2019年的每一年yyyy： yyyy_de_dl.tif 包含通过样条重建得到的季中早期（6月10日至8月10日）与季末（8月10日至9月10日）地面沉降估算结果。 yyyy_timeseries.tif 包含经规则采样的无约束地面沉降时序数据。 对应观测日期如下： 2017年：['20170604T173314', '20170616T173315', '20170628T173316', '20170710T173316', '20170722T173317', '20170803T173318', '20170815T173318', '20170827T173319', '20170908T173319'] 2018年：['20180611T173321', '20180623T173322', '20180717T173323', '20180729T173324', '20180810T173325', '20180822T173325', '20180903T173326'] 2019年：['20190606T173327', '20190618T173327', '20190630T173328', '20190712T173329', '20190724T173330', '20190805T173330', '20190817T173331', '20190829T173332', '20190910T173332']
