What is this data?
The data was collected by ESA (European Space Agency) satellite launched in 2002, which carried an array of nine Earth-observation instruments that gathered information using a variety of measurement principles. ASAR (Advanced Synthetic Aperture Radar) was the largest single instrument, operated in the C- band in a wide variety of modes, detecting changes in surface height with sub-millimeter precision.
Currently Envisat is inoperative; ESA formally announced the end of its mission in May 2012.
