Detecting methane emissions during COVID-19
While carbon dioxide is more abundant in the atmosphere and therefore more commonly associated with global warming, methane is around 30 times more potent as a heat-trapping gas. Given its importance, Canadian company GHGSat have worked in collaboration with the Sentinel-5P team at SRON Netherlands Institute for Space Research to investigate hotspots of methane emissions …
Help EC to shape the next Green Deal call
In February 2020, ESA (Directorate of Earth Observation Programmes – EOP) and EC (Directorate-General for Research and Innovation – R&I) launched a joint Earth System Science Initiative, formalised with the signature of a working arrangement between both institutions. The initiative aims at joining forces to advance Earth System Science and provide a coordinated response to …
SWARM+ 4D DEEP EARTH: CORE project
Prime company: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS) (FR)The goal of the 4D-Earth-Swarm project, supported by ESA, is to improve our understanding of the rapid (interannual) changes in the geomagnetic field, as recorded by the three satellites of the Swarm mission of ESA – as well as earlier satellite missions such as CHAMP and Oersted, and ground-based observatories. The project is planned for …
A collaboration on Atmosphere science just kicked-off
Trace gases are produced and destructed by physical, biological and chemical processes. This natural cycle has been perturbed over the past decades by the global population increase and by the related boost of anthropogenic activities. The composition of the atmosphere is undergoing major and rapid changes with significant impacts on a global scale, affecting the …
8th international symposium on gas transfer at water surfaces
Plymouth, United Kingdom
The Gas Transfer at Water Surfaces (GTWS) meeting occurs every 5 years and brings together approximately 150 scientists from countries all over the world. The focus is on the physicochemical and biogeochemical processes that govern atmosphere-water gas exchange and fluxes, which include turbulence, shear, breaking waves, bubbles and natural and anthropogenic surfactants. Biological and chemical …
Is the global COVID-19-related drop in NO2 pollution coming to an end?
All over the world, countries have – to a greater or lesser extent – taken measures to reduce the spread of the coronavirus. In particular, people movements have been restricted worldwide. The decrease in traffic and industrial activity, the two main sources of nitrogen dioxide (NO2) in urban areas, led to unprecedented decreases in NO2 …
Systematic swath elevation and monthly DEMs over the Greenland Ice Sheet margin from CryoSat
The CryoTEMPO-EOLIS (Elevation Over Land Ice from Swath) product, now operationally available at on the CryoSat Dissemination Server, exploits CryoSat’s SARIn mode and the novel Swath processing technique to deliver increased spatial and temporal coverage of time-dependent elevation over land ice, a critical metric for tracking ice mass trends. This is the outcome of a …
20-year time-series of global primary production in the oceans
In a recent paper published in Remote Sensing, scientists used data from the Ocean Colour Climate Change Initiative to study the long-term patterns of primary production and its interannual variability. Combining long-term satellite data with in situ measurements, they assessed global annual primary productivity from 1998-2018. Being able to observe and quantify primary production over …
Mapping methane emissions on a global scale
An important new tool to combat climate change is now available. Using data from the Copernicus Sentinel-5P satellite, this new technology makes it possible to track and attribute methane emissions around the world. Read the full story.
