The firm Kayrros and its partners, the LSCE (CEA-CNRS-UVSQ) and INRAE, are launching the first measurement platform to monitor, on a regional scale, the capacity of forests to reduce atmospheric CO2. These open access data are based on spatial observations of biomass and capitalize on nearly 30 years of research.
The Biomass Carbon Monitor provides data going back to 2011, and will be updated four times per year. It provides governments, forest managers and citizens with science-based validated information to monitor the evolution of the carbon stocks contained in forests and, in particular, to measure the losses induced by extreme climate events.
Globally, the data show that some 760 million metric tons of carbon per year were removed from the atmosphere and stored by forest. This removal of carbon offsets the annual CO2 emissions associated from China during the same period. However, while most forests in the northern hemisphere trap carbon, many tropical regions affected by deforestation release carbon.
The following is an overview of what has been observed since 2011:
"This is a revolutionary tool that complements the inventories and spatial observations already available, by providing comprehensive information on how the carbon stored by biomass evolves over time," says Philippe Ciais, a researcher at the LSCE.The Biomass Carbon Monitor is based on observations by the SMOS (Soil Moisture and Ocean Salinity) mini-satellite of the European Space Agency (ESA). Its instruments make it possible to probe the entire vegetation layer, not just the top of the canopy. This approach is particularly adapted to dense vegetation and semi-arid regions, for which very few ground-based inventories are available. It allows seasonal monitoring of carbon losses and gains by vegetation, in relation to climate change. Click here for more information.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
