InSAR stacks of southern Kyushu, Japan from ALOS

This repository contains the InSAR products used in Yunjun et al., 2021 (GRL). It includes two stacks of unwrapped interferograms in southern Kyushu Island, Japan from ALOS-1 ascending and descending orbit, respectively. Dataset 1: ALOS ascending track 424 frame 620-630. Date: 24 June 2006 - 7 April 2011 (29 acquisitions; 225 interferograms) Processor: ISCE-2/stripmapStack Configurations: AlosAT424F620_630.txt Dataset 2: ALOS descending track 73 frame 2970-2980 Date: 7 January 2007 - 20 April 2011 (21 acquisitions; 115 interferograms) Processor: ISCE-2/stripmapStack Configurations: AlosDT73F2970_2980.txt This is an input dataset (loaded in HDF5/MintPy format) for the time series analysis with MintPy. The HDF5/MintPy file (*.h5) structure is described in https://mintpy.readthedocs.io/en/latest/api/data_structure/. <pre><code># compress the folder and split into multiple files using multiple cores tar cvf - AlosAT424F620_630 | pigz -9 -p 6 | split -b 4000m - AlosAT424F620_630.tar.gz tar cvf - AlosDT73F2970_2980 | pigz -9 -p 6 | split -b 4000m - AlosDT73F2970_2980.tar.gz # untar/uncompress the multiple files cat AlosAT424F620_630.tar.gz* | tar xvfz - cat AlosDT73F2970_2980.tar.gz* | tar xvfz - </code></pre>本仓库收录了Yunjun等人2021年发表于《地球物理研究通讯(Geophysical Research Letters, GRL)》的研究中所使用的合成孔径雷达干涉测量(InSAR, Interferometric Synthetic Aperture Radar)产品。数据集包含两组分别来自日本九州南部区域的ALOS-1升轨与降轨解缠干涉图堆叠。 数据集1：ALOS升轨轨道424，幅编号620-630。时间跨度为2006年6月24日至2011年4月7日，共包含29景影像与225幅干涉图。处理软件为ISCE-2/stripmapStack，配置文件为AlosAT424F620_630.txt。 数据集2：ALOS降轨轨道73，幅编号2970-2980。时间跨度为2007年1月7日至2011年4月20日，共包含21景影像与115幅干涉图。处理软件为ISCE-2/stripmapStack，配置文件为AlosDT73F2970_2980.txt。 本数据集为采用MintPy进行时间序列分析的输入数据集，以HDF5/MintPy格式存储。HDF5/MintPy格式文件（*.h5）的结构说明可参考：https://mintpy.readthedocs.io/en/latest/api/data_structure/。 以下为文件夹压缩与分块传输的多核心加速命令： <pre><code># 使用多核心压缩文件夹并分块 tar cvf - AlosAT424F620_630 | pigz -9 -p 6 | split -b 4000m - AlosAT424F620_630.tar.gz tar cvf - AlosDT73F2970_2980 | pigz -9 -p 6 | split -b 4000m - AlosDT73F2970_2980.tar.gz # 解压合并分块文件 cat AlosAT424F620_630.tar.gz* | tar xvfz - cat AlosDT73F2970_2980.tar.gz* | tar xvfz - </code></pre>
