Japanese term meaning wave (“nami”) in a harbour (“tsu”). A series of travelling waves of extremely long length and period, usually generated by disturbances associated with earthquakes occurring below or near the ocean floor. (Also called seismic sea wave and, incorrectly, tidal wave). Volcanic eruptions, submarine landslides, and coastal rock falls can also generate tsunamis, as can a large meteorite impacting the ocean. These waves may reach enormous dimensions and travel across entire ocean basins with little loss of energy. They proceed as ordinary gravity waves with a typical period between 10 and 60 minutes. Tsunamis steepen and increase in height on approaching shallow water, inundating low-lying areas, and where local submarine topography causes the waves to steepen, they may break and cause great damage. Tsunamis have no connection with tides; the popular name, tidal wave, is entirely misleading.

Landsat Collection 2 Surface Temperature products are generated from several input data sources and atmospheric profiles. This includes NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Emissivity Dataset (GED).   The ASTER GED dataset is created from all clear-sky pixels of ASTER scenes acquired from 2000 through 2008. While this dataset has a global spatial extent, there are areas that are  missing the mean emissivity information due to persistent cloud contamination in the ASTER measurements. When mean emissivity information is missing, the Surface Temperature product will contain areas of missing data.  Learn more: Landsat Collection 2 Surface Temperature data gaps due to missing ASTER GED
