Datacubes of InSAR time series for active volcanoes

Datacubes of InSAR time series for the 20 volcanoes (*) flagged in the paper "Large-scale demonstration of machine learning for the detection of volcanic deformation in Sentinel-1 satellite imagery" by Biggs et al. (Bull Volc, 2022). Each file contains the time series of cumulative displacements for one volcano in the *.nc format. There are four fields with "DATA" : cumulative LOS displacements (unit=meters), "lon" : longitude (unit=degrees), "lat" : latitude (unit=degrees) and "time" : number of days since the first date. The first date can be found in the attribute "units" of the variable "time". (*) The five volcanoes: Sierra Negra, Fernandina, Cerro Azul, Wolf and Alcedo volcanoes are contained in the single file "galapagos_128D_09016_110500.nc".本数据集涵盖Biggs等人2022年发表于《火山学通报》（Bull Volc）的论文《机器学习在哨兵1号（Sentinel-1）卫星影像火山形变检测中的大规模演示》中标记的20座火山的合成孔径雷达干涉测量（Interferometric Synthetic Aperture Radar, InSAR）时间序列数据立方体。每个文件以nc格式存储单座火山的累积位移时间序列。文件包含四个字段："DATA"字段存储累积视线向（Line-of-Sight, LOS）位移（单位：米），"lon"字段存储经度（单位：度），"lat"字段存储纬度（单位：度），"time"字段存储距首次观测日期的天数；首次观测日期可通过变量"time"的"units"属性获取。注：其中5座火山——Sierra Negra、Fernandina、Cerro Azul、Wolf及Alcedo火山，均包含在单个文件"galapagos_128D_09016_110500.nc"中。
