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, …
The active fire detection capability of the SLST sensor on board of the Copernicus constellation of Sentinel 3A and Sentinel 3B is being exploited by the European Space Agency to derive systematic consistent counting of fires worldwide. The prototype product and algorithm have been presented at the Remote sensing of forest fire EARSeL conference in …
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
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 Arctic is warming twice as fast as the global average, with consequences felt across the whole planet. A better scientific understanding of the complexities of the fragile Arctic environment is critical for policy decisions on climate-change mitigation and adaptation, and for setting up a framework for managing Arctic development sustainably. The Multidisciplinary drifting Observatory …
The Advanced Training Course on Land Remote Sensing: Agriculture is taking place now (16-20 September) at UCLouvain outside Brussels. During the entire week 92 PhD students, postdocs, specialists and experts from international agencies and the European Commission are following lectures in the morning and doing hands-on exercises using software tools in the afternoon. The course …
The quality of estimations for carbon export and sequestration depends on how well the spatio-temporal dynamics of non-algal particles in open ocean are understood. Non-algal particles include organisms such as bacteria or viruses, cell debris and other organic particles, as well as mineral particles, bubbles and plastics. The accumulation of these particles is only partially …
Lack of in-situ measurements of ice temperature (boreholes) limit our capabilities to understand ice sheet dynamics. Researchers combined L-band (1.4 GHz) passive microwave observations from SMOS over Antarctica with glaciological and emission models to infer information on glaciological properties of the ice sheet at various depths, including temperature. Comparison with existing models showed that differences …
ESA’s Earth System Data Lab is a new virtual lab to access a wide array of Earth observations across space, time and variables. It consists of two elements: the data cube and an interface to execute different analyses on the data cube. Young researchers selected in the Early Adopters Call launched in 2018 used the …
