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

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)
