title: InSAR time-series for the Kirishima volcanic complex in Kyushu, Japan from ALOS-1/2

description: This repository contains the InSAR displacement products used in Yunjun et al., 2021, GRL (submitted). It includes the InSAR observations (time-series and average velocity) and geodetic modeling results of the Kirishima volcanic complex from ALOS-1 during 2006-2011 and from ALOS-2 during 2015-2019 in both ascending and descending orbits. SAR data Overview: ALOS-1 ascending track 424 frame 620-630 (24 June 2006 - 7 April 2011; 29 acquisitions) ALOS-1 descending track 73 frame 2970-2980 (7 January 2007 - 20 April 2011; 21 acquisitions) ALOS-2 ascending track 131 frame 620 (30 September 2014 - 2 July 2019; 36 acquisitions) ALOS-2 descending track 23 frame 2970 (9 Feburay 2015 - 19 August 2019; 49 acquisitions) InSAR stack in HDF5/MintPy format: AlosAT424F620_630.tar.gz: https://zenodo.org/record/4499238 AlosDT73F2970_2980.tar.gz: https://zenodo.org/record/4499238 Alos2AT131F620.tar.gz: https://zenodo.org/record/4499208 Alos2DT23F2970.tar.gz: https://zenodo.org/record/4499208 InSAR time-series (for all acquisitions) in HDF-EOS5 format: ALOS_SM_424_0620_0630_20060624_20110407_N31880_N31980_E130820_E130920.he5 ALOS_SM_073_2970_2980_20070107_20110420_N31880_N31980_E130820_E130920.he5 ALOS2_SM_131_0620_20140930_20190702_N31880_N31980_E130820_E130920.he5 ALOS2_SM_023_2970_20150209_20190819_N31880_N31980_E130820_E130920.he5 InSAR time-series (for acquisitions before destructive eruptions for better spatial coverage) in HDF-EOS5 format: ALOS_SM_424_0620_0630_20060924_20101120_N31880_N31980_E130820_E130920.he5 ALOS_SM_073_2970_2980_20070107_20110118_N31880_N31980_E130820_E130920.he5 ALOS2_SM_131_0620_20140930_20171010_N31880_N31980_E130820_E130920.he5 ALOS2_SM_023_2970_20150209_20170918_N31880_N31980_E130820_E130920.he5 InSAR average velocity in HDF5/MintPy format: VEL_ALOS_A424_20080929_20100705.h5 VEL_ALOS_D073_20081012_20100302.h5 VEL_ALOS2_A131_20150106_20171010.h5 VEL_ALOS2_A131_20171219_20190702.h5 VEL_ALOS2_D023_20150209_20170918.h5 VEL_ALOS2_D023_20171211_20190819.h5 Unwrapped interferograms of the 2011 Shinmoe-dake eruption (reconstructed from time-series): AlosAT424_20100102_20101120.unw (pre-eruptive inflation).
