EUMETSAT & CNR with GEO-K united by an Algorithm

/in , , , /da

On 20 of May 2016, at the EUMETSAT Headquarters in Darmstadt, Germany, GEO-K signed a new contract for a study about cloud detection over sea ice using the “Sea and Land Surface Temperature Radiometer” (SLSTR) instrument aboard on Sentinel 3 satellite.

Sea ice is typically present on polar oceans of the planet and has a crucial role on climate. Therefore, monitoring its morphological structure, its changes and its temperature is important to have a clear picture of the actual and future climate state.

To do these kind of observations at best, it is important that the satellite view is completely free of clouds, then it becomes necessary an algorithm that can distinguish a white brilliant cloud from an ice surface also white and shiny. GEO-K, in collaboration with ISAC-CNR (Italian Institute of Atmospheric Science and Climate) as subcontractor, will supply such an algorithm.

The people involved in this project are: Massimiliano Sist (GEO-K), Lia Santoleri (ISAC-CNR) and Gianluigi Liberti (ISAC-CNR).

 

GEO-K StormTrek at 2015 EUMETSAT Meteorological Satellite Conference

/in , , , , /da

“The number of the extreme meteorological events has increased in the last few years and the trend should be the same for the next future”.

GEO-K participated in the 2015 EUMETSAT Meteorological Satellite Conference, held in Toulouse, France, 21-25 September, presenting StormTrek, the innovative algorithm for the nowcasting of extreme meteorological events.

“These events generally develop very quickly and on a small scale, nevertheless they may provoke several damages and affect also the human’s safety. For these reasons it is very important to monitor and prevent these natural hazards by means of advanced techniques which must be able to:
● detect the event as soon as possible
● track the behavior of the event
● predict the short term development of the event

StormTrek is a novel multispectral algorithm for the detection, the tracking and the short term forecast of convective objects developed by GEO-K.
The model is already operational and some web services based on its output are already available. Our work is aimed to show the results of the validation activity developed in the last year. StormTrek validation involves the comparison with benchmarks like the Rapid Development Thunderstorms, developed by Meteo France, and the lightning activity over Europe and South Africa”.
