This study investigates a method for best member selection of a Limited area model Ensemble Prediction System (LEPS) with the goal to increase quantitative precipitation forecast. A case study that occurred between 22-24 May 2002 over Calabria, southern Italy, is discussed. Mediterranean storms often develop under upper level disturbances which are usually associated with high values of potenti...

Satellite data are the main source of information in Numerical Weather Prediction (Szyndel (2003)), with 99% of the available data for global numerical weather prediction (NWP) being satellite based. It should also be noted that satellites are one of the few observing systems that can provide data at sufficiently high temporal and spatial frequency for regional and mesoscale models. The derivat...

The combination of measurements from different satellite instruments for the estimation of precipitation is a promising way to overcome the shortcomings of measurements from a single data source. EUMETSAT realised the Multi-sensor Precipitation Estimate (MPE) in order to combine the advantages of the high temporal and comparably high spatial resolution of a geostationary IR sensor with the high...

Geostationary meteorological satellites are recently receiving a great deal of attention from the aerosol remote sensing community due to their increasingly advanced performances including ability acquire multiple views Earth per day. However, this type observing systems limited by partial coverage globe, which makes them inappropriate for monitoring long-range-transported particles or assimila...

Meteosat Second Generation (MSG) is the new generation of European geostationary meteorological satellites operated at EUMETSAT. SEVIRI, the MSG main radiometer, measures the reflected solar radiation within three spectral bands centered at 0.6, 0.8 and 1.6 m, and within a broad band similar to the VIS channel of MVIRI, the radiometer on-board the first generation of METEOSAT satellites. The op...

Satellite image Security is playing a vital role in the field of communication system and Internet. This work is interested in securing transmission of Meteosat images on the Internet, in public or local networks. To enhance the security of Meteosat transmission in network communication, a hybrid encryption algorithm based on Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA) al...

On 21 September 2012 the entire sky was covered by contrails over the Gulf of Lyon (NW of the Mediterranean basin). These clouds were well recorded by ground observers as well as by Meteosat imagery. The atmospheric characteristics at the levels where these anthropic clouds formed are analyzed by performing a WRF simulation in the area where Meteosat recorded contrail clouds. According to the v...
