Take5 Spot4 Level 2A

At the end of life of each satellite, CNES issues a call for ideas for short-term experiments taking place before de-orbiting the satellite. In 2012, CESBIO seized the opportunity to set up the Take 5 experiment at the end of SPOT4′ life : this experiment used SPOT4 as a simulator of the time series that ESA’s Sentinel-2 mission will provide.

On January 29, SPOT4’s orbit was lowered by 3 kilometers to put it on a 5 day repeat cycle orbit. On this new orbit, the satellite will flew over the same places on earth every 5 days. Spot4 followed this orbit until June the 19th, 2013. During this period, 45 sites have been observed every 5 days, with the same repetitivity as Sentinel-2.

Take5 Spot4 L2A are data ortho-rectified surface reflectance after atmospheric correction, along with a mask of clouds and their shadows, as well as a mask of water and snow.
