The potential of using satellite-related precipitation data sources in arid regions

In this chapter the general factors affecting the equilibrium and stability of arid regions are discussed, with particular focus given to rainfall, the primary factor influencing the continuity and development of these environments. Unfortunately, the scarcity or complete lack of rain gauges in such areas complicates the collection of sufficient rainfall data. Consequently, systematic steps are proposed toward the development of alternative analyses of the spatiotemporal distribution of rainfall in arid regions. The foremost approach is the incorporation of remote sensing data, along with the appropriate classifiers, into the indirect evaluation of rainfall. For the purpose of assessing the suitability of the proposed methods, a detailed study on rainfall in the eastern side of the Gulf of Suez in Egypt is presented.
