The Earth Observation (EO) value adding sector is characterised by a high number of small and specialized companies operating in specific application domains; building the complete vertical stack by themselves. While they excel in their core business, they lack IT competences and resources to publish and market their information extraction algorithms via modern on-line platforms. …
Incomplete avalanche activity datasets introduce uncertainty to avalanche forecasting Roughly 150-250 people die each year in avalanche accidents. Infrastructure loss and costs from evacuations and road closures and the use of active and permanent mitigation measures amount to large economic costs. Regional avalanche forecasting is an active mitigation measure that informs the public of …
Observing phenomena occurring in remote locations at high latitudes is not an easy task. Apart from the scarcity of in-situ measurements available in locations such as Greenland, satellite observations with optical sensors are often hindered by the presence of clouds and lack of sunlight during wintertime. That is why scientists look at ways to combine …
The annual European Geosciences Union General Assembly is the largest and most prominent European geosciences event. Annually, it attracts over 14,000 scientists from all over the world, of which more than half are early career scientists. The EGU General Assembly 2019, taking place in Vienna (Austria) on 7–12 April 2019, will bring together geoscientists from …
The unprecedented spatial resolution offered by Copernicus Sentinel-5P’s Tropomi instrument means that we can now better analyse the complex relationship between tropospheric ozone and climate.
The loss of ice from Antarctica is one of the principal causes of contemporary sea level rise. Tracking the changes that are currently occurring across this remote and inaccessible continent requires systematic satellite monitoring programmes. From these unique observational platforms, robust long-term climate records can be developed, which help scientists to understand and to predict …
A good aircraft heating was necessary to secure proper functioning of the on-board instrumentation during the airborne campaign that took place last November in the Arctic, flying between Ottawa and Iqaluit. The campaign exploited several radars and lidars to measure cloud particles and precipitation by looking at signals bouncing off ice crystals and water droplets …
This activity is focused on the exploitation of the Synthetic Aperture (SAR) and Synthetic Aperture Interferometric (SARin) modes measurements of CryoSat-2 and Sentinel-3A and Sentinel-3B in the coastal and inland water domains. It is motivated by the need to maximise the use of the SARin mode from CryoSat and the SAR mode of the operational …
The possibility to operationally monitor the Earth’s land cover (changes) at high temporal resolution is nowadays given by EO multispectral dense time series available at global level, in particular Sentinel-2 and Landsat 8 data. Nonetheless, keeping thematic maps regularly updated is a complex and time consuming task. Large efforts have been devoted to date in …
Regional sea level trends present large spatial patterns caused by natural variability (changes in winds, air-sea flux etc.) along with anthropogenic influences in the atmosphere. These sea level trends can be partially masked by random oceanic processes. Global mean sea level rise is one of the most direct consequences of the on-going global warming. Based …
