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, the land and the ocean is regulated through fluxes between these three …
Considering the long-term goal for Digital Twin Ocean (DTO) of being a virtual representation of the marine environment including all its known features and dynamics, the DTO-p project proposes to: Define a concept of a DTO, implement and demonstrate to a relevant stakeholder community and ESA; Create a solid scientific and technical basis upon which …
With this ITT ESA aims at exploring the full capacity of the latest EO satellite data, and in particular of the unprecedented wide variety of European satellite Earth observations, to better characterise and understand the drivers and complex underlaying processes leading to high impact multi-hazards with a focus on cascade and compound events as well …
A catalogue of publicly available geoscience products, datasets and resources developed in the frame of scientific research projects funded by ESA EO. Products vary in geographical and temporal extent, production methodology, validation and quality.
Time to apply for the Earth Observation (EO) training course organised in collaboration between ESA and the NASA Jet Propulsion Laboratory (JPL): deadline for application is 15 July 2022. The course will take place on 19 – 23 September 2022 at the premises of the Andoya Space Centre (ASC) in Andenes, Norway. Intended for researchers, …
The detection of trace gas plumes allows us to improve attribution of pollutant emissions and photochemical processing in the global troposphere. Data collected by the ESA TROPOspheric Monitoring Instrument (TROPOMI) has resulted in a growing number of case studies that have used ad hoc methods to detect plumes for science applications. Developing a more comprehensive …
GlaMBIE project builds on nascent efforts within the IACS working group on Regional Assessments of Glacier Mass Change (RAGMAC, https://cryosphericsciences.org/activities/wg-ragmac/) to setup and coordinate an intercomparison exercise of regional glacier mass changes from glaciological in-situ measurements and various remote sensing sources, including geodetic DEM differencing, altimetry, and gravimetry. Under the guidance of Scientific Advisory Committee …
Clouds play an important role in the energy budget of our planet: optically thick clouds reflect the incoming solar radiation, leading to cooling the Earth, while thinner clouds act as “greenhouse films”, preventing escape of the Earth’s long-wave radiation to space. Cloud response to ongoing greenhouse gases climate warming is the largest source of uncertainty …
What is the mechanism linking the unexpected August 2021 rainfall on Greenland with snow and ice melt on the ice sheet? Researchers from GEUS (Geological Survey of Denmark and Greenland), leading the Pre-Operational Sentinel-3 snow and ice products (SICE) project, highlighted a feedback framework where, before the rain, warm atmospheric rivers triggered melting which exposed darker …
Stratospheric ozone (the “ozone layer”) protects the biosphere from harmful UltraViolet (UV) radiation. Ozone (O3) is expected to recover as a consequence of the Montreal Protocol signed in 1987 and its Amendments regulating the phase-out of ozone-depleting substances (ODS). The stratospheric halogen amount (mainly bromine and chlorine) released by ODSs reached its maximum abundance in …
