Download or read book Short-range Forecasting of Cloudiness and Precipitation Through Extrapolation of GOES Imagery written by H. Stuart Muench and published by . This book was released on 1981 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development and testing of an objective technique to forecast cloudiness and precipitation through extrapolation of satellite imagery. By utilizing on objectively determined cloud-motion vector, the technique makes local forecasts of satellite parameters (brightness and IR temperature), with high temporal resolution, using simple linear extrapolation. Algorithms are then used to convert the satellite parameters to total cloud cover, probability of 1-hour precipitation, and presence of low, middle, and high clouds. The test program computed motion vectors and made forecasts out to 7 hours, in half-hour steps, at 30 locations. The program was tested on 12 spring and fall cases, using half-hourly GOES imagery. For periods beyond 2 hours, forecasts of cloud cover and precipitation were markedly better than persistence, which deficiencies in specification hindered short-period performance. Forecasts of cloud layers were worse than persistence due to inadequate specification algorithms. The net results were quite encouraging, and further refinements and developments are planned.

Download or read book Specification of Current and Future Cloud Amounts and Ceilings from Satellite Data written by John H. Conover and published by . This book was released on 1975 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective methods and their accuracies for deriving current and six-hour forecasts of cloud amount and ceiling from satellite data are presented. Data from the visible and IR window bands were tested to develop relationships. The IR data did not significantly improve the results. The visible data were carefully calibrated, navigated, and normalized for solar elevation and bidirectional reflectance. Cloud motions were also used for the six-hour forecasts. The data were reduced to values of average brightness and its standard deviation over 1/2 deg by 1/2 deg areas before analysis. RMSE of current cloud amounts (on a scale of 0 to 1) are about 0.25 and for six hours later about 0.35. The occurrence of a ceiling/no ceiling was specified correctly 80% and 70% of the time at zero and six hours, respectively. Various methods are shown for minimization of ceiling errors over different height ranges. In general, RMSE of specified and forecast ceilings range from 4000 to 6000 ft at low levels to 9000 to 10,000 ft at mid and high levels. (Author).

Book excerpt: The 7-volume Encyclopedia of Biodiversity, Second Edition maintains the reputation of the highly regarded original, presenting the most current information available in this globally crucial area of research and study. It brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes of the work include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity. The science of biodiversity has become the science of our future. It is an interdisciplinary field spanning areas of both physical and life sciences. Our awareness of the loss of biodiversity has brought a long overdue appreciation of the magnitude of this loss and a determination to develop the tools to protect our future. Second edition includes over 100 new articles and 226 updated articles covering this multidisciplinary field— from evolution to habits to economics, in 7 volumes The editors of this edition are all well respected, instantly recognizable academics operating at the top of their respective fields in biodiversity research; readers can be assured that they are reading material that has been meticulously checked and reviewed by experts Approximately 1,800 figures and 350 tables complement the text, and more than 3,000 glossary entries explain key terms
