In air traffic management (ATM) all necessary operations (tactical planing, sector configuration, required staffing, runway configuration, routing of approaching aircrafts) rely on accurate measurements and predictions of the current weather situation. An essential basis of information is delivered by weather radar images (WXR), which, unfortunately, exhibit a vast amount of disturbances. Thus,...

An information system, called HelioClim, is available for answering the needs for long-term time-series of solar radiation data. Daily irradiation values are available over Europe, Africa and Atlantic Ocean, from 1985 onwards. This database is accessible through the Soda Web service (http://www.soda-is.com) on a free basis. Meteosat satellites images are used to produce this climatological data...

The SEVIRI instrument on the Meteosat Second Generation satellite with both fine spatial and temporal resolution allows to detect and follow the dynamics of fast developing meteorological events like spreading smoke plumes and the lifecycles of convective clouds. Smoke plumes have the ability to change the atmospheric heat content due to 5 absorption and reduced reflection of solar radiation. B...

Meteosat 8 SEVIRI with its good spectral, spatial and temporal resolutions provides an excellent basis for the monitoring and nowcasting of fog. Based on this the present study outlines a method for fog detection using SEVIRI data, with algorithms for both, night and daytime. The night algorithm is ported from NOAA AVHRR and relies on brightness temperature differences between the 10.8 and 3.9 ...

An improved independent precipitation data set with the horizontal resolution of 7×7 km grid over central Europe was generated (Free University of Berlin (FUB)precipitation analysis). For scale dependent evaluation of the Local model (LM) of the German Weather service, the precipitation data were separated into convective and stratiform fractions. To analyse precipitation amounts an interpolati...

The paper discusses the sensitivity of the height assignment of optically thin cirrus clouds to satellite calibration errors. Thin cirrus are often used as tracers for the derivation of high-level wind vectors. The height assignment is based on bi-spectral techniques, which in the case of Meteosat use both the IR (10.5 12.5 μm) and WV (5.7 7.1 μm) channels. Height allocation errors for typical ...

The aim of the study is the individuation of convective cells over the Italian peninsula with the conjunction use of geostationary satellite data (METEOSAT, MSG satellite) in the IR and WV channels and lightning data. We will use GCD (Global Convective Diagnostic) algorithm developed at Aviation Weather Centre (AWC) of NOAA (National Oceanic and Atmospheric Administration). This algorithm is ba...

The COVID-19 pandemic led to a 72% reduction of air traffic over Europe in March–August 2020 compared 2019. Modeled contrail cover declined similarly, and computed mean instantaneous radiative forcing dropped regionally by up 0.7 W m?2. Here, model predictions cirrus optical thickness the top-of-atmosphere outgoing longwave reflected shortwave irradiances are tested comparison Meteosat-SEVIRI-d...

We employed the combined WRF-Chem-RTFDDA model to forecast dust storms in Middle East and North Africa (MENA). WRF-Chem simulates emission, transport, mixing, chemical transformation of trace gases aerosols simultaneously with meteorology. RTFDDA continuously assimilates both conventional nonconventional meteorological observations provides improved initial conditions for analyses forecasts. wa...
