Abstract:
For the hazards menacing controlled and uncontrolled aviation space as volcanic ash plumes, fire smoke, or dust and sand storms, it was found that the satellite imagery is a very powerful tool not only as research but as a monitoring one. As a consequence of the eruption of Eyjafjallajökull in 2010, a lot of synergic actions were taken by international organizations in order to create a common space of research, investigation and monitoring of the volcanic activity. This study aims to be a Near Real Time exercise of monitoring a volcanic ash plume, vegetation fires smoke and Saharan dust intrusions with satellite tools and their products facilities. When detecting volcanic ash clouds from satellite it appears a problem, which is a discriminating one (ATBD, 2011). Assessing the nature of the aerosol clouds is a matter of fine tuning of the satellite imagery and products. For example, the Red Green Blue (RGB) technique is very useful in identifying volcanic clouds, but it does not discriminate between ash and SO2 (C. Zehner, Ed. 2010). Therefore, we have chosen some examples of world-wide eruptions monitored by satellite underlining the importance of the “split window “or “inverse absorbtion”.
