Interlevel correlations of temperature and density, surface to 60 km by Allen E Cole( Book )
2 editions published in 1980 in English and held by 17 WorldCat member libraries worldwide
Statistical techniques have been developed which can be used to determine the effect of density and temperature on the trajectories of reentry vehicles for altitudes between the surface and 60 km. Arrays of monthly means and standard deviations of density and temperature at 2-km intervals of altitude to 60 km, together with interlevel coefficients of correlation of density with density and temperature, are provided for the mid-season months (January, April, July, October) at 10 locations between latitudes 8 deg. and 64 deg. N. These data are in format that can be easily used to estimate the distributions of vertical density and temperature gradients and the effects of day-to-day density variations on the trajectories of reentry vehicles
Wind-speed extremes in the Northern Hemisphere, 30 through 60 km by Arthur J Kantor( Book )
3 editions published in 1983 in English and held by 14 WorldCat member libraries worldwide
This report provides northern hemisphere maps of monthly 90-, 95-, and 99-percentile scalar speeds (10-, 5-, and 1-percent extremes) for altitudes 30 through 60 km. Observed meridional and zonal mean winds and their associated standard deviations were used to derive the magnitude of the mean monthly wind vectors and vector standard deviations. Extreme scalar speeds were then calculated from the magnitudes of the vector means and vector standard deviations, assuming a circular normal distribution. The data used to derive these values consist of wind measurements at and above 30 km from 8 years of data at 12 Meteorological Rocket Network (MRN) stations in the northern hemisphere. Also presented are tables of monthly and annual 10-, 5-, and 1-percent wind-speed extremes at each of the 12 MRN stations. (Author)
Some comparisons between probabilities of cloud-free lines-of-sight estimated from aircraft and from sky cover observations by Iver A Lund( Book )
1 edition published in 1980 in English and held by 12 WorldCat member libraries worldwide
For a period of more than 6 years, aircrews made observations of the presence, or absence, of clouds on lines-of-sight between the aircraft and the surface of the earth. These observations were used to estimate the probability of a cloud-free line-of-sight (CFLOS) from a given altitude at a given angle. The probabilities obtained from observations in the vicinity of six stations in the United States were compared with probabilities estimated from routine sky-cover observations taken by weather observers at these stations. A model was used to transform sky-cover observations to CFLOS probabilities. The estimates obtained from the model were generally higher than those obtained from the aircrews' observations. If it is assumed that probabilities obtained from the samples of aircrew observations are better estimates of the true probabilities than estimates inferred from frequency distributions of sky cover categories, the CFLOS probabilities obtained from the CFLOS model are biased. The CFLOS model will yield CFLOS probabilities for any hour of the day, season of the year, and altitude at any geographical location where routine observations of sky cover, altitude and amount are taken. When the model probabilities are increased to correct for bias, they provide good estimates of true probabilities of a CFLOS. (Author)
Winter space correlations of pressure, temperature, and density to 16 km by Eugene A Bertoni( Book )
5 editions published in 1964 in English and held by 11 WorldCat member libraries worldwide
"The winter vertical and horizontal correlations between pressure, temperature, and density at fixed geopotential heights, to 16 km, are presented for 27 observation stations in the Atlantic Ocean and Europe. Many figures are shown to depict the decay of correlation both in the horizontal and in the vertical direction. A small effort directed toward improving the simple Markov decay function met with little success"--Abstract
Clear lines-of-sight from aircraft by Eugene A Bertoni( Book )
2 editions published in 1967 in English and held by 10 WorldCat member libraries worldwide
An in-flight observation program to collect observations of the presence, or absence, of clear lines-of-sight at several angles in the vertical plane has been completed. Approximately 72,000 observations were collected over a period of about 15 months. Observations were taken by flight crews of the Air Force, Navy, and Pan American Airways. Data were obtained over most of the Northern Hemisphere, except the area from 30E to 110E. All observations taken within a 10 deg latitude-longitude sector were grouped together by altitude and season. The relative frequency of a clear line-of-sight is plotted in the appropriate area on maps for various lines-of-sight. The number of observations on which the relative frequency is based is shown in parentheses. The relative frequencies are intended to serve as estimates of the probabilities of clear lines-of-sight. These estimates should be considered as a first approximation since, (a) the observations were taken in a very subjective manner, (b) the estimates are based only on about one season of data, and (c) cloud variability may be quite large within some 10 degree sectors.

Clear and Cloud-Free Lines-of-Sight from Aircraft ( )
1 edition published in 1977 in English and held by 1 WorldCat member library worldwide
The AFGL in-flight line-of-sight program that was initiated to collect observations of the presence, or absence, of clouds and haze on lines- of-sight at various elevation angles form aircraft has been completed. Approximately 270,000 unique observations were collected. Observations were taken by flight crews of the U.S. Air Force, U.S. Navy, American Airlines, several other U.S. commercial carriers, and NATO countries. Data were obtained over most of the Northern Hemisphere. Observations taken within a 10 deg latitude-longitude sector were grouped together by altitude and season. The relative frequency of clear and cloud-free lines-of-sight are plotted in appropriate areas on Northern Hemisphere maps for various angular lines-of- sight. This paper describes the in-flight line-of-sight program, illustrates the presentation of data gathered, and gives a few examples of the utilization of this information

Atlas of cloud-free line-of-sight probabilities. Part 5. North Africa and the Middle East by Iver A Lund( Book )
1 edition published in 1979 in English and held by 1 WorldCat member library worldwide
This is the fifth part of a planned Northern Hemisphere atlas of probabilities of cloud-free lines-of-sight between the earth and space. The probabilities are for the mid-season months: January, April, July, and October; four times of day: 0000-0200 LST, 0600-0800 LST, 1200-1400 LST, and 1800-2000 LST; and three elevation angles: 10, 30 and 90 deg. Parts 1, 2, 3, and 4 depicted cloud-free line-of-sight probabilities for Germany, the USSR, the USA, and Europe, respectively
