NASA's ARIA Along-Track Deformation Map
NASA's ARIA Along-Track Deformation Map Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA’s Jet Propulsion Laboratory in Pasadena, California, and Caltech, also in Pasadena, using synthetic aperture radar (SAR) data from the Japanese Aerospace Exploration Agency (JAXA) Advanced Land Observing Satellite-2 (ALOS-2) PALSAR-2, generated maps of the deformation of Earth’s surface caused by the Sept. 28, 2018 magnitude 7.5 earthquake under Sulawesi island, Indonesia, near the city of Palu. The along-track deformation map measures horizontal deformation in the satellite-track direction, roughly south.  The false-color maps show the amount of permanent surface movement that occurred almost entirely due to the quake, as viewed by the satellite, during a 42-day interval between two ALOS-2 wide-swath images acquired on August 20 and October 1, 2018 (both UTC).

GPM IMERG precip measurements from Hurricane Michael
Video of GPM Rainfall Data From Michael This animation shows the NASA Integrated Multi-satellitE Retrievals for GPM (IMERG) rainfall accumulation estimates from Hurricane Michael October 1- 5, 2018 when rainfall was getting more concentrated over the western Caribbean. The Global Precipitation Measurement mission or GPM's constellation of satellites provides rainfall data to make rainfall estimates. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA. IMERG indicated that rainfall accumulation totals of over 12 inches fell in the Caribbean Sea east of Honduras during this period.

GPM overpass of hurricane michael on 10/8/18
The GPM Microwave Imager (GMI) has 13 channels that view different aspects of the hurricane in different ways. This overpass of Hurricane Michael on Oct. 8th, 2018 shows the combined low, mid, and high-frequency GMI channels along with the retrieved rain rate for the same overpass developed by combining all channels to understand the precipitation structure.

NASA's AIRS Captures Hurricane Michael 
NASA's Aqua satellite flew over Hurricane Michael on October 8, 2018 at 2:47 p.m. EDT (1847 UTC). The NASA AIRS instrument captured Hurricane Michael's strongest storms. AIRS also captured a thick band of storms feeding into the center from the eastern quadrant. In those areas cloud top temperatures as cold as -63 degrees Fahrenheit were found. Storms with cloud top temperatures this low have the capability to produce heavy rainfall.

NASA's MODIS Instrument Captures Hurricane Michael
On October 8, 2018 the MODIS instrument aboard NASA's Aqua satellite captured a visible image of Hurricane Michael when it was a Category 1 hurricane near the western tip of Cuba. Aqua is a NASA Earth Science satellite mission collecting information about the Earth's water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. Additional variables also being measured by Aqua include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures.

ARIA DPM Update
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and Caltech in Pasadena, CA created a Damage Proxy Map (DPM) version 0.7 depicting areas in Central Sulawesi, Indonesia, including the city of Palu that are damaged. The damaged areas are depicted as red and yellow pixels. Damage occurred as a result of the magnitude 7.5 earthquake on September 28, 2018. The map is derived from synthetic aperture radar (SAR) images from the ALOS-2 satellite, operated by Japan Aerospace Exploration Agency (JAXA).  The map covers an area of 67 by 70 kilometers, shown by the large red polygon. Each pixel measures about 30 meters across. The color variation from yellow to red indicates increasingly significant ground surface change. Preliminary validation was completed through collaboration with the Earth Observatory of Singapore comparing local media information and photos. Damage proxy maps are used as a guide to identify damaged areas; however, the maps may be less reliable over vegetated areas. For example, the scattered single colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does mean that damage has not occurred. The DPM was created by the NASA-JPL / Caltech ARIA team, and the ALOS-2 data was provided by JAXA. The Earth Observatory of Singapore coordinated with the Sentinel Asia to timely task the ALOS-2 satellite. The algorithm development was carried out at JPL under a contract with NASA.
