Available in PDF, EPUB and Kindle. Book excerpt: Amplitude scintillations of the radio energy from the galactic radio source Cassiopeia A were examined for the total solar eclipse of July 20, 1963, using the 150-foot parabolic antenna at the AFCRL Sagamore Hill Radio Observatory, Hamilton, Massachusetts. The extent of eclipsing varied along the ionospheric ray path from 100% at about 100 km to about 80% near 500 km. Chart recordings of the amplitude variations of the Cassiopeia A signal were made at frequencies of 29.8, 63, 113, and 228 Mc/s. The extent of variation in amplitude and rate of scintillation was comparable to that on control days. Examination of the frequency dependence showed that the scale size of the irregularities did not change significantly during the period of the eclipse. No effects in the scintillation records could be related uniquely to the reduction of ionizing illumination and subsequent cooling of the medium. (Author).

Download or read book A Verification of the Use of the Effective Vertically Integrated Standard Deviation of the Wind in Estimating Dispersion of Vertically Rising Balloons written by George F. Nolan and published by . This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monthly dispersion patterns of vertically rising balloons for various probability levels are computed for the altitude of 90,000 ft by using the effective vertically integrated standard deviation of the wind. These are representative of conditions at the Holloman AFB - White Sands Missile Range complex. The use of this procedure to obtain a reliable measure of dispersion is verified by testing with individually computed ascent trajectories. The importance of considering interlevel correlation coefficients in estimating dispersion is emphasized by the results of this study. The resulting dispersion patterns afford a means of increasing balloon operational efficiency and effectiveness for the cited area by defining the best locations for target flight launchings, and by giving the probable dispersions for flights launched from a fixed site. The findings of this study can also be of assistance in planning balloon operations at other midlatitude locations. (Author).

Download or read book Evaluation of Infrared Emission of Clouds and Ground as Measured by Weather Satellites written by Clifford Dalton Kern and published by . This book was released on 1965 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of prime interest are the radiation data from that portion of the infrared spectrum known as the atmospheric water-vapor window, ranging from about 8 to 12 microns. Infrared signals received by weather satellites and aircraft depend, in clear air, on surface temperature, atmospheric interference and surface emissivity. For the latter, very different data in literature are found for clouds, water, rocks, etc. In this report correct emissivity data were sought in three ways: (1) Reflectivity of polished rock samples was tested in an infrared spectrograph for 5-16 microns wavelength. Using Kirchhoff's law this method yielded emissivities for near normal incidence. (2) Using an 8-13 microns sensitive radiometer and an aggregate, called emissivity box, the emissivity of many surfaces was measured directly. (3) A summer noon time flight of Tiros over the Mediterranean and the Sahara was evaluated.
