GCOS target requirements for Biomass were set as follows (GCOS-200):
Variable/Parameter | Horizontal Resolution | Vertical Resolution | Temporal Resolution | Accuracy | Stability |
---|---|---|---|---|---|
Aboveground Biomass | 1 km | N/A | Annual | < 20% error for biomass values > 50 t/ha, and < 10% for biomass values ≤ 50 t/ha | N/A |
LPV Biomass contributes toward action items T36, T52, T53, T54, T55, T56 (2016 IP, GCOS-200).
The CEOS WGCV LPV Biomass Focus Area, in collaboration with the CEOS Land Surface Imaging - Virtual Constellation (LSI-VC) Forests & Biomass focus area, and others within CEOS contributing to the Agriculture, Forestry and Other Land Use (AFOLU) global stocktake, have created dashboard for the visualization of biomass products.
The Biomass Earthdata Dashboard was created by the NASA-ESA Multi-mission Algorithm and Analysis Platform (MAAP), and multiple biomass products are currently being analyzed through an open science Biomass Harmonization Activity that utilizes the MAAP.
GEDI launch, December 5, 2018
SAOCOM-1B Launch, Aug 30, 2020
There are currently ten BIOMASS-relevant missions expected to provide biomass estimations this decade.
The biomass focus area is engaged with the CEOS agencies involved, and will collaborate on site information and protocol development to maximize the utility of data, tools, and information for the benefit of all missions.
Below are details of recent and upcoming missions related to biomass estimation. At right are two recent successful mission launches.

The CEOS ad hoc Space Data Coordination Group (SDCG) for the Global Forest Observations Initiative (GFOI) was created to support the GFOI and forest carbon tracking. The biomass focus area collaborates with the SDCG and GFOI and together will promote the uptake of the forthcoming biomass protocol.
NASA and ESA have collaborated on a project together to support aboveground biomass research. The project is called the Multi-Mission Alogrithm and Analysis Platform (MAAP). The MAAP project will bring together data, algorithms and compute together in a cloud environment to address challenges of sharing and processing multiple data sources related to NASA and ESA missions, such as BIOMASS, NISAR, and GEDI.
GEO-TREES: Forest Biomass Reference System from Tree-by-Tree Inventory Data. This is a community-led activity to support the ongoing collection of new high-quality biomass reference data and the distribution and sharing of these data, building on existing networks and partnerships. This project, initiated in January 2021, was borne out of the CEOS LPV Validation Protocol development effort, and has recently received a very large (12M USD) investment from the Bezos Earth Fund. The GEO-Trees efforts will be coordinated by the Smithsonian Tropical Research Institution.
