Summary:

The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology, both in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas in Northeastern Mozambique, that are likely damaged (shown by red and yellow pixels) as a result of Cyclone Kenneth. The map was derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellite, operated by the European Space Agency (ESA). The images were taken before (April 16, 2019) and after (April 28, 2019) the landfall of the cyclone (Category 4) on April 25, 2019.

Suggested Use:

The color variation from yellow to red indicates increasingly more significant ground surface change. This damage proxy map should be used as guidance to identify damaged areas, and 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 not necessarily mean no damage.

Satellite/Sensor:

Synthetic Aperture Radar (SAR) on European Space Agency's (ESA) Copernicus Sentinel-1A satellite

Resolution: 30 meters

Credits:

Contains modified Copernicus Sentinel data (2019) analyzed by the NASA-JPL/Caltech ARIA team. The DPM was created by the NASA-JPL/Caltech ARIA team in collaboration with the Earth Observatory of Singapore (EOS), and the data were provided by the European Space Agency. The algorithm development was carried out at JPL under a contract with NASA.
