Download or read book Point Comparisons of Total Cloud Cover from Satellites and from Surface Observations written by Patrick J. O'Reilly and published by . This book was released on 1973 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report compares cloud-cover observations made by ground observers and relative cloud-cover estimates determined from satellite-measured brightness values. Comparisons are made when each type of cloud (9 low type, 9 middle type, and 9 high type) are found alone and also with various combinations taken over the China mainland and portions of Southeast Asia. Satellite observations from the ESSA and ITOS series of satellites are used. Both tabulated and graphical presentations of the results are included along with the author's comments on the investigative procedures and findings.

Download or read book Global Atlas of Relative Cloud Cover 1967 70 written by Donald B. Miller and published by . This book was released on 1971 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atlas was prepared from data acquired during the period January 1, 1967, through December 31, 1970. Picture signals were computer processed to prepare hemispheric charts of monthly, seasonal, semiannual, and annual charts of relative cloud cover, in octas, over both the Northern and Southern Hemispheres. Similar presentations of tropical cloudiness are included. This atlas is one of the first attempts to use satellite data in the preparation of a climatology of daytime cloudiness over the globe.

This book was released on 1995 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cloud-climate feedback is one of the most important factors in predicting the timing and magnitude of global climate change and its regional effects. Recent satellite measurements indicate that global effects of clouds on solar and infrared radiation are large. The experimental objective of the Atmospheric Radiation Measurement (ARM) Program is to characterize, empically, the radiative processes in the Earth's atmosphere with improved resolution and accuracy. Therefore, the effective treatment of cloud formation and cloud properties is crucial for reliable climate prediction. This study focuses on the analysis of cloud cover data for the ARM Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site central facility. The data set was obtained from the Advanced Very High Resolution Radiometer (AVHRR) on National Oceanic and Atmospheric Administration (NOAA) Satellites 11 and 12, and cloud observations made by SGP CART site operators. Such an analysis provides a basis for future evaluations with whole-sky cameras and provides a means of assessing the reliability of surface-based observations of cloud cover at the SGP CART site.

Available in PDF, EPUB and Kindle. Book excerpt: A global cloud cover data set, derived from the USAF 3D NEPH Analysis, was developed for use in climate studies and for Earth viewing applications. This data set contains a single parameter - total sky cover - separated in time by 3 or 6 hour intervals and in space by approximately 50 nautical.miles. Cloud cover amount is recorded for each grid point (of a square grid) by a single alphanumeric character representing each 5 percent increment of sky cover. The data are arranged in both quarterly and monthly formats. The data base currently provides daily, 3-hr observed total sky cover for the Northern Hemisphere from 1972 through 1977 less 1976. For the Southern Hemisphere, there are data at 6-hr intervals for 1976 through 1978 and at 3-hr intervals for 1979 and 1980. More years of data are being added. To validate the data base, the percent frequency of or = 0.3 and or = 0.8 cloud cover was compared with ground observed cloud amounts at several locations with generally good agreement. Mean or other desired cloud amounts can be calculated for any time period and any size area from a single grid point to a hemisphere. The data base is especially useful in evaluating the consequence of cloud cover on Earth viewing space missions. The temporal and spatial frequency of the data allow simulations that closely approximate any projected viewing mission. No adjustments are required to account for cloud continuity.

This book was released on 1965 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cloud cover--as shown by various types of data such as surface observations, satellite photographs, U-2 photographs, and vertically pointing radar--was analyzed to provide information on clouds as an obstacle to vision through the atmosphere. In these studies the photographic data were used to assess the extent to which significant operational knowledge can be derived from surface cloud observations. Comparison of surface observations with U-2 and TIROS photographs shows that surface observations are frequently not representative of cloud cover over even a small fraction of the distance between adjacent stations. Time changes in cloud cover were determined from hourly cloud observations and were summarized to show the probability of extended periods of various amounts of cloud cover. Comparison of probabilities for different seasons and different geographic locations is included. The probabilities of seeing specific locations along latitudes 15, 30, and 45 degrees N were determined from nephanalyses of TIROS photographs and surface synoptic reports. These probabilities are given for the four seasons, and the effects of synoptic features on these probabilities are discussed. The report also contains cloud top altitudes measured from U-2 photographs and thicknesses of cloud layers with bases at various heights as shown by a vertically pointing radar. (Author).
