This book was released on 1978 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques to estimate reentry vehicle weather erosion parameters from satellite measurements are described. The techniques were developed over a period of three years. An empirical approach was followed with simultaneous measurements of clouds by aircraft and satellite sensors in a series of 41 cases covering a great range of cloud conditions. For each case the aircraft measurements of clouds supplemented by surface weather reports and radar pictures were converted to profiles of hydrometeor densities vs altitude. The erosion parameters predict the amount of material eroded from a nosetip and the range error of the reentry system due to erosion by ice and water particles in the atmosphere. The erosion parameters were related to infrared and visible satellite imagery data from NOAA ITOS satellites by means of non-linear equations. Equations were also developed to estimate total cloud mass and thickness from the same satellite data. Extensive applications and tests were made of the equations to estimate erosion parameters from satellite data.

This book was released on 1980 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A weather erosion parameter known as the Environmental Severity Index (ESI) has been estimated using infrared and visible data from satellites. Cloud sampling requirements limited the original prediction equations to satellite data averaged over a horizontal scale of 70 km. Further experiments have demonstrated great utility for satellite estimates on a scale of 10 km and also revealed some systematic differences between the coarse and the fine scale estimates. The ESI averages 1 percent to 10 percent higher for the fine scale estimates and high values of ESI are observed more frequently. (Author).

This book was released on 2012-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains most of the invited papers presented at the International Workshop on Light Scattering by Irregularly Shaped Particles held on June 5-7, 1979. at the State University of New York at Albany (SUNYA). Over seventy participants representing many dis ciplines convened to define some of the ever-increasing number of resonant light-scattering problems associated with particle shape and to relate their most recent investigations in this field. It is obvious from the two introductory papers that an investi gator's primary discipline determines his/her approach to the light scattering problem. The meteorologist, Diran Deirmendjian, advocates an empirical methodology: to model the scattering by atmospheric aerosols, using equivalent spheres as standards, in the most effi cient and simplest manner that is consistent with remote sensing, in situ, and laboratory· data. Because of the almost infinite variety of particle shapes, he questions not only the possibility but even the usefulness of the exact solution of scattering by a totally arbitrary particle. The astrophysicist, J. Mayo Greenberg, is primarily concerned with the information content carried by the scattered light because this radiation is the sole clue to under standing the nature of interstellar dust. What measurements (polar ization, color dependence, etc ••• ) should be made to best determine a given particle characteristic (size, surface roughness, refractive index, etc ••• )? Thus, he considers the physics of the scattering process to be of paramount interest.

Available in PDF, EPUB and Kindle. Book excerpt: Several current programs in satellite meteorology at the Air Force Geophysics Laboratory are reviewed. First of all, the use of reflected sunlight at both visible and near infrared frequencies to distinguish snow from clouds is described. Secondly, a technique of compositing pictures of many typhoon cases in order to relate cloud features to typhoon motion is discussed. Finally, the use of visible and infrared imagery to estimate erosion parameters for reentry systems is described. (Author).
