The validation of satellite-based land products relies heavily on in-situ or fiducial reference measurements (FRMs) collected over an ensemble of globally representative sites, providing consistent, high quality and traceable reference data. These sites must ensure adequate representation of different land cover and ecoclimatic conditions to enable unbiased satellite data validation at global scale. Evolving validation […]
Wildfires are uncontrolled fires which burn in an area of combustible vegetation. In the right conditions, they can quickly become out of control and hence early identification, as well as ongoing monitoring and management, is critical. The challenge to monitor and control wildfires is increased due to their location in rural or remote areas, which […]
Spaceborne hyperspectral sensors provide contiguous spectral coverage of the Earth’s surface within the optical and infrared spectrum, enabling the derivation of several biogeophysical products and user applications. Atmospheric correction (AC) is essential for processing satellite data because it removes the effects of the atmosphere (e.g., aerosols, water vapor and dust) that alter the signal before […]
Workshop on Integrating Global AFOLU Datasets into National Carbon Inventory Systems Concludes! Under the CEOS umbrella, two weeks of learning concluded, bringing together SE Asia government agencies, universities, and powerhouse organizations like the Japanese Space Agency (JAXA), the US Geological Survey SilvaCarbon Program, The Food and Agriculture Organization of the United Nations (FAO), and the […]
This article is the second in a series of seven articles describing the role and work of the CEOS Virtual Constellations. The series of articles is as follows: Atmospheric Composition (AC-VC) Land Surface Imaging (LSI-VC) (this article) Ocean Colour Radiometry (OCR-VC) Ocean Surface Topography (OST-VC) (coming soon) Ocean Surface Vector Wind (OSVW-VC) (coming soon) Precipitation […]
Biomass, the living part of vegetation systems, plays a crucial role in climate. Around half of biomass is carbon, so when vegetation is destroyed, as in deforestation, carbon dioxide is released to the atmosphere. This is a huge source of atmospheric carbon – about 6 billion tons of carbon dioxide per year. At the same […]
The CEOS Coastal Observations, Applications, Services, and Tools (COAST) Ad Hoc Team is pleased to announce our upcoming community webinar, co-hosted by the Group on Earth Observations (GEO). Engaging Users in Solving Coastal Issues When: October 5th, 2021 | 14h00-15h30 CEST Objectives: Share information about CEOS COAST Illustrate how Earth observations (EO) help inform evidence-based […]
