Because the COP30 local weather convention will get underway in Brazil, the world’s consideration is as soon as once more drawn to the plight of the Amazon – the planet’s largest and most important rainforest. With the European Area Company’s Earth Explorer Biomass satellite tv for pc now in orbit, ESA helps Brazil put together to rework this new mission’s groundbreaking knowledge into actionable data for shielding the rainforest and confronting local weather change.
Launched earlier this yr, the Biomass mission is designed to unlock novel insights into how forests are altering and their pivotal function in regulating Earth’s carbon cycle.
It’s the first satellite tv for pc to hold a P-band artificial aperture radar – its sign able to penetrating forest canopies to measure woody biomass: trunks, branches and stems. These measurements function a proxy for carbon storage, the evaluation of which is the mission’s main goal.
The supply of those novel measurements is, no doubt exceptional, however it is vital that customers are geared up with the know-how to take advantage of them to their full potential.
To this finish, ESA, the Brazilian Nationwide Institute for Area Analysis (INPE) and the Brazilian Area Company (AEB) not too long ago joined forces in Belém to evaluate how greatest to take advantage of Biomass’ knowledge.
ESA’s Head of Inexperienced Options Division, Inge Jonckheere, mentioned, “We’re working to bridge the hole between obtainable satellite tv for pc knowledge and their sensible utility in Brazil’s nationwide monitoring efforts, together with reporting to worldwide local weather frameworks.
“Collaborating carefully with our Brazilian companions is crucial to make sure that Biomass and different satellite tv for pc knowledge are absolutely built-in into their knowledge processing methods, supporting the creation of native, nationwide and regional knowledge merchandise.”
ESA’s Biomass Processor Growth Supervisor, Muriel Pinheiro, famous, “Biomass is the primary P-band artificial aperture radar mission in house, and its knowledge are anticipated to carry unprecedented perception into forest construction.
“Getting ready the Brazilian forestry neighborhood for utilizing all of the Biomass knowledge merchandise is key, not solely to make sure the early uptake of the info, but additionally to advertise unbiased validation, which is absolutely aligned to the mission’s open-science oriented technique.”
Alessandra Gomes from INPE, added, “The INPE–ESA collaboration will permit scientists to judge how the ESA Biomass mission can present new and unprecedented insights into world forest carbon dynamics, particularly within the Amazon the place cloud cowl and dense cover situations make monitoring notably difficult.”


Because of the lengthy wavelength of P-band, the radar sign, relying on the polarisation, emitted by the Biomass satellite tv for pc penetrates the entire forest layer and the sign is scattered again by the person parts of the forest cover.
On this means, the measured sign carries details about the forest construction and can be utilized to deduce parameters corresponding to forest biomass and forest top.
A be aware on the photographs
The primary picture, inside the textual content above, is a map for reference and a strip displaying Biomass knowledge which depicts forest top in a bit of rainforest that stretches from northern Brazil to Suriname. This seize additionally features a nook of the Tumucumaque Mountains Nationwide Park.
Then the 2 side-by-side pictures above reveal the forest at completely different heights. The picture on the left reveals the forest ground, whereas the picture on the best captures the cover about 30 metres above the bottom.
The vertical profile beneath is a bit of forest within the Tumucumaque Mountains Nationwide Park, deep within the Amazon rainforest – it gives a glimpse into how forest construction varies throughout the panorama.
Stefano Tebaldini, Affiliate Professor on the Politecnico di Milano and who leads the science for Biomass, mentioned, “The Biomass satellite tv for pc carries a completely polarimetric artificial aperture radar, which means it may well transmit and obtain indicators in two orthogonal linear polarisations – horizontal and vertical.
“Every polarisation channel supplies several types of details about the forest. However to seize particulars corresponding to forest top and the construction beneath the cover, the satellite tv for pc should go over the identical space a number of instances – a method often known as artificial aperture radar interferometry. Biomass can be the primary radar mission in house to incorporate a devoted tomographic section, permitting us to construct vertical cross-sections of forested areas.
“In brief, deciphering and making use of the eventual knowledge – Biomass remains to be in its commissioning section – is a posh course of, however ESA helps to be sure that customers can absolutely harness this info for science and environmental administration.”
It’s vital to notice that the Biomass satellite tv for pc remains to be in its commissioning section, so these knowledge will not be but appropriate for scientific use. Nonetheless, with ESA’s steerage, examples like these are already serving to Brazil’s scientific neighborhood put together for the wealth of knowledge the mission will quickly ship.
In the meantime, at COP30, ESA’s Head of Actionable Local weather Info Part, Clement Albergel, mentioned, “Policymakers from nations across the globe are right here assessing progress below the Paris Settlement.
“ESA’s function, on this respect, is to offer clear and dependable knowledge that permits nations to trace their progress and strengthen nationwide local weather motion – our fundamental effort right here is carried out by our Climate Change Initiative, to which the Biomass mission will contribute as soon as it’s absolutely commissioned.
“Nonetheless, the worth of efforts made to assist nations use particular knowledge for their very own wants can’t be underestimated, notably in the case of assessing the well being of forests and the way they’re being altered, which might be tackled as a part of the general Earth Motion factor of ESA’s FutureEO programme.”
