  • Global Precipitation Estimation from Satellite Image Using Artificial Neural Networks
    Global Precipitation Estimation from Satellite Image Using Artificial Neural Networks Soroosh Sorooshian, Kuo-lin Hsu, Bisher Imam, and Yang Hong Department of Civil and Environmental Engineering University of California, Irvine E-4130 Engineering Gateway Irvine, CA 92697-2175 Email: [email protected]; phone: 949-824-8825; fax: 949-824-8831 ABSTRACT Better understanding of the spatial and temporal distribution of precipitation is critical to climatic, hydrologic, and ecological applications. However, in those applications, lack of reliable precipitation observation in remote and developing regions poses a major challenge to the community. Recent development of satellite remote sensing techniques provides a unique opportunity for better observation of precipitation for regions where ground measurement is limited. In this presentation, we introduce a satellite-based precipitation measurement algorithm named PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks). This algorithm continuously provides near global rainfall estimates at hourly 0.25o x 0.25o scale from geostationary satellite longwave infrared imagery. An adaptive training feature enables model parameters to be constantly adjusted whenever independent sources of precipitation observations from low-orbital satellite sensors are available. The current PERSIANN algorithm has been used to generate multiple years of research quality precipitation data. This data has been used to characterize the variations of water and energy cycle at various spatial and temporal scales. PERSIANN data is available through HyDIS (Hydrologic and Data Information System: http://hydis8.eng.uci.edu/persiann/) at CHRS (Center for Hydrometeorology and Remote Sensing), UC Irvine. The system development of PERSIANN algorithm, data service, and applications are discussed. 1 Introduction Precipitation is the key hydrologic variable linking the atmosphere with land surface processes, and playing a dominant role in both weather and climate.

But we know that it is a question of a kind of important metabolism, which it is in the interest of mankind to discern, since the shortage of reserves of fresh water threatens to hinder its development. Let us just emphasise, in the more general field of scientif- ic research, two attitudes which, it seems to us, should characterise the scientist, and especially the scientist who is a Christian. On the one hand, he must honestly consider the question of the earthly future of mankind and, as a re- sponsible person, help to prepare it, preserve it, and elimi- nate risks; we think that this solidarity with future genera- tions is a form of charity to which a great many men are sensitive today, in the framework of ecology. But at the same time, the scientist must be animated by the confi- dence that nature has in store secret possibilities which it is up to intelligence to discover and make use of, in order to reach the development which is in the Creator’s plan.
