Above-ground biomass in tons/ha estimated from SAR images, acquired by Copernicus Sentinel-1A in 2015, for a 150 x 90 km2 east-west transect in Southern Sweden, including the lakes of Vänern and Vättern.
The region is characterised by productive forests, cropland, pasture and lakes. Detailed and up-to-date information on forest biomass obtained with Sentinel-1 imagery support the work of forest agencies, land owners, climate and environmental modellers.

Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission is currently a constellation with two satellites, Sentinel-2A and Sentinel-2B; a third satellite, Sentinel-2C, is currently undergoing testing in preparation for launch in 2024.[4]
The mission supports a broad range of services and applications such as agricultural monitoring, emergencies management, land cover classification or water quality.
Sentinel-2 has been developed and is being operated by the European Space Agency, and the satellites were manufactured by a consortium led by Airbus Defence and Space.
The Sentinel-2 mission has the following key characteristics:
