Background The carbon cycle is central to the Earth system, being inextricably coupled with climate, the water cycle, nutrient cycles and the production of biomass by photosynthesis on land and in the oceans. In the natural system the balance among carbon in the atmosphere, land and ocean is regulated through fluxes between these three …
Based on the new possibilities of the Sentinel series of satellites, this project aims to develop a highly novel approach to derive global fire emissions estimates based on the characterisation of individual fires and their behaviour. These data will be combined with bottom-up estimates of fuel and combustion and top-down constraints on total carbon emissions …
ESA’s upcoming Biomass mission will deliver valuable P-band SAR data aimed at forest aboveground biomass (AGB) estimation across the humid tropics. Additionally, the current NASA GEDI mission on the International Space Station (LiDAR), the NASA NISAR and JAXA ALOS-4 (L-band SAR) will widen our possibilities to estimate AGB from space. However, all these missions rely on …
This online event, held within the context of POLINSAR 2021, aims at: Providing an objective, standardized comparison and assessment of biomass retrieval algorithms developed for the BIOMASS, NISAR and GEDI missions, and fusion of these mission datasets; Establishing a forum to involve scientists in the development of retrievals that have so far not been part …
Objective of this work is to assess time-space variability of terrestrial gross primary production and the contribution to its estimation using observations of land surface temperature, solar induced fluorescence, fraction of absorbed photosynthetically active radiation and land cover offered at multiple resolution as well as other records from other ESA and non-ESA missions.
A paper published recently in Earth System Science Data describes how scientists working in the OceanSODA project used measurements from ships and from satellites to show how ocean waters have become more acidic over the last three decades. Read the full story.
Gross primary production (GPP), the total carbon fixation by terrestrial ecosystems through vegetation photosynthesis, is being affected by drought and heat events. Previous studies have demonstrated how the duration and the intensity, as well as the timing of such events are controlling the GPP. A research conducted within the framework of the Earth System Data …
The IPCC Special Report on the Ocean and Cryosphere in Changing Climate (2019) includes “permafrost carbon and greenhouse gas emissions” as one of the cases characterised by deep uncertainty. The report states that even if there is a very high confidence that “permafrost temperatures have increased to record high levels including the recent increase by …
The project aims at improving a current surface albedo generation system by adapting and integrating a deep learning system for cloud detection, an advanced atmospheric correction model which considers the surface BRDF effects, and a new technology allowing to retrieve high-resolution albedo from high-resolution reflectance by combining with downscaled MODIS BRDF climatology
The ESA Methane+ project aims at exploiting the SWIR and TIR CH4 observations from different satellites in order to better differentiate between sources and sinks of CH4 on the regional and global scale. For this we will use the CH4 observations of TROPOMI on Copernicus Sentinel-5p, IASI on MetOp-B, and CrIS on Suomi NPP in combination with atmospheric inversion models. OBJECTIVES: Given the identified opportunities and challenges of …
