ALOS-2

Overview

The Advanced Land Observing Satellite-2 (ALOS-2) is follow-on mission from the "DAICHI", which contributed to cartography, regional observation, disaster monitoring, and resource surveys. ALOS-2 will succeed this mission with enhanced capabilities.

Specifically, JAXA is conducting research and development activities to improve wide and high-resolution observation technologies developed for DAICHI in order to further fulfill social needs.

Flood Proxy Map depicting areas of Southeastern Texas that are likely flooded as a result of Hurricane Harvey, shown by light blue pixels.
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this Flood Proxy Map depicting areas of Southeastern Texas that are likely flooded as a result of Hurricane Harvey, shown by light blue pixels. The map is derived from synthetic aperture radar amplitude images from the European Space Agency's (ESA) Sentinel-1 satellite, taken before (August 5, 2017) and after (August 29, 2017) Hurricane Harvey made landfall...

NASA-Produced Maps Help Gauge Italy Earthquake Damage
NASA/JPL-Caltech-produced maps of damage in and around Amatrice, Italy, from the Aug. 2016, quake, based on ground surface changes detected by Italian and Japanese radar satellites. The color variations from yellow to red indicate increasingly more significant ground surface change. Credits: NASA/JPL-Caltech/JAXA/ASI/European Union - Joint Research Centre/Google Earth A NASA-funded program provided valuable information for responders and groups supporting the recovery efforts for the Aug...

Flood extent map created by the ARIA team at NASA-JPL/Caltech, derived from the ALOS-2 ScanSAR data acquired 8/27/17 (~1:30PM Central Time) over Texas including Houston.
The above image is a screenshot of the flood extent map created by the ARIA team at NASA-JPL/Caltech, derived from the ALOS-2 ScanSAR data acquired on 8/27/17 (~1:30PM Central Time) over Texas including Houston. This Flood Proxy Map (FPM) covers an area of 350-by-350 km and is derived from Japan Aerospace Exploration Agency's (JAXA's) ALOS-2 PALSAR-2 pre- (2017-07-30) and post-event (2017-08-27) Synthetic Aperture Radar (SAR) amplitude images. The pixels in light...

Radar image of Amatrice Italy Earthquake
NASA and its partners are contributing observations and expertise to the ongoing response to the Aug. 23, 2016, magnitude 6.2 Amatrice earthquake in central Italy caused widespread building damage to several towns throughout the region. This earthquake was the strongest in that area since the 2009 earthquake that destroyed the city of L'Aquila. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory, Pasadena,...
