Abstract: A numerical solar radiation model based on standard meteorological data was revised for clouds using data from the GARP Atlantic Tropical Experiment (GATE). Climatic-mean transmittance functions were revised for low and ...

Abstract: The incorporation of diagnostic data obtained from surface observations into a humidity analysis at the 850-, 700- and 500-mb levels is tested using European surface and upper-air data for 22 observation times in February ...

Abstract: A unique set of data was collected during a large-scale field study of diffusion about an urban complex at Fort Wayne, Ind. Observations of turbulent wind fluctuations were obtained on two towers, one in a typical rural ...

Abstract: Data generated by a physically based solar radiation model, consisting of hourly values of total and direct-beam solar radiation, were computed at nearly 50 stations in the United States for the years 1971 and 1972. The ...

Abstract: Hourly values of total solar radiation are computed by two methods at 11 stations in all regions of the United States for a two-year period. In the first method, precipitable water is computed from radiosonde observations ...

Abstract: The spatial and temporal characteristics of cloud coverage during the 21-day GATE Phase 111 period were studied using SMS-1 infrared hourly digitized data and standard hourly meteorological surface observations taken on ...

Abstract: An examination is made of the hypothesis that the inconclusive or marginal effects of many cloud seeding operations are due, at least in part, to an inhomogeneous distribution of freezing nuclei resulting in great ranges ...

Abstract: A method is developed for the semi-objective analysis of layered cloud amounts and of heights of cloud bases and tops. The analyses are based on satellite television and infrared data, surface synoptic observations and ...

Abstract: A radiation model was used to simulate daily incoming solar radiation at four ships during Phase III of GATE. The accuracy of the simulations from several different cloud analyses based on ship or satellite data was estimated ...

Abstract: Northern Hemisphere surface-synoptic and radiosonde data from November 1961 through February 1962 are used to develop diagnostic relationships between surface-observed variables at a single station and the dewpoint spread ...
