Four seasons of Thomas Pesquet's shelterbelt by Sentinel-2

=>

On Feb 16 2017, French Astronaut Thomas Pesquet shot this photo from the International Space Station.



Thomas' followers quickly spotted a shelterbelt or windbreak in South Russia, near Volgograd [1]. Astronauts pictures are great to show the value of Earth observation from space. However for science applications, Thom_Astro cannot compete with Sentinel-2 satellites, which provide systematic, multispectral, coverage of the land surface, with a constant acquisition angle.
 
Below is a selection of four images taken by Sentinel-2A of the same site. On the autumn image, a thin layer of snow blown by the wind brings out the asperities of the surface. In the spring the melting snow reveals this fertile black soil or chernozem, which covers the great Russian steppes.
