With its 900 km of shoreline, #NewYork city (like many other cities that border an ocean) is at risk of flooding due to rising sea levels. . Data show that since 1993, the global mean sea level has risen, on average, just over 3 mm every year. 📸 @CopernicusEU #Sentinel2.The upcoming @copernicus_eu Sentinel-6 Michael Freilich satellite, set to launch in November from California, US, is the first of two identical satellites that will provide observations of sea level change. Each Sentinel-6 satellite carries an altimeter that works by measuring the time it takes for radar pulses to travel to Earth’s surface and back again to the satellite. Combined with precise satellite location data, altimetry measurements yield the height of the sea surface. .
