Height systems and related sea level observations are based on a number of measurement systems, which all have their own characteristics and deliver different type of observations. Traditionally, sea level is observed at tide gauge stations, which usually also serve as height reference stations for national levelling networks and therefore define a height system of …
The S5P+I-OC project will explore the capacity of the Sentinel-5p TROPOMI data to provide novel Ocean Colour (OC) products. More specifically, the objectives of this S5P+ Innovation activity are to: develop a solid scientific basis for the application of S5P data within the context of novel scientific and operational OC products applications; assess existing algorithms …
In the frame of the ESA Regional Initiatives, a set of coordinated activities between science, public sector, industry growth and infrastructure components focussing on regional priorities with high interest for Member States, a number of Science and Application projects are being runned for the Black Sea and Danube region. In this context, the EO4SIBS (Earth …
Steve is a nighttime optical phenomenon shown to be associated with intense subauroral ion drifts (SAID). The phenomenon is described as a purple band of light equatorward of aurora and it is sometimes accompanied by periodic green emissions termed “picket fence”. There are several hypotheses on the physical mechanisms that could be causing Steve and …
Polar regions are undergoing major and drastic changes with significant impact at global scale. Addressing this unique set of global challenges will require more than ever that scientists advance their understanding of the different drivers governing changes in Polar regions, its associated processes and its potential impacts and translate that knowledge into solutions for society, …
As described in the Statement of Work (SoW) document for the Swarm+ Coupling: High-Low Atmosphere Interactions, recent studies have revealed “a clear response of the low-latitude ionosphere to the large-scale meteorological events in the stratosphere called Sudden Stratospheric Warming events (SSW)”. In response to ESA ‘s Invitation to Tender (ITT), VERtical coupling in Earth’s Atmosphere at …
The recent IPCC Special Report on the Ocean and Cryosphere highlights how we all depend on oceans and ice, and how they are intrinsic to the health of our planet – but stresses the many ways in which they are being altered by climate change. Read the full article
SMOS Sea Surface Salinity (SSS) is not yet widely used by the ocean modelling community. In part this is due to the technical challenges of assimilating satellite SSS and assessing the impact of the assimilation using objective tools and reporting. The Global Ocean Data Assimilation Experiment (GODAE) Ocean View Science Team (GOV-ST) group Observing System …
Methane continues to increase in our atmosphere, and now researchers want to quantify the role of high Northern latitudes to this increase. Earth-observing satellites open the window to this remote, rapidly changing environment. Carbon cycle in the Arctic and boreal regions links strongly to the evolving cryosphere – ice, snow and frost. Especially natural methane …
The Swarm+ Coupling: High-Low Atmosphere Interactions ITT Statement of Work (SoW) has highlighted the “compelling scientific problem” of “the least-understood causes of planetary winds,” namely planetary outflows induced by “non-thermal (e.g., frictional heating, particle precipitation, wave-particle acceleration) processes.” The Swarm+ Coupling High-Low Atmosphere Interactions: Ion Outflow (“Swarm+ Outflow”) project, which began in May 2019, centers …
