This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a data report which provides temperature, wind speed, sound speed, effective sound speed and mean global cloud cover data for use by those involved in monitoring compliance with a CTBT (Comprehensive Test Ban Treaty) and, in particular, for those concerned with infrasonic monitoring per se. The temperature, wind speed, sound speed and effective sound speed data are zonally averaged data obtained from the COSPAR (Committee on Space Research) International Reference Atmosphere: 1986 (0 km to 120 km). The data set is available from NASA's National Space Science Data Center, includes only the lower atmospheric altitude range extending from 0 km to 120 km and consists of tables of monthly mean values of temperature and zonally averaged wind speed for the latitude range 80 deg S to 80 deg N in 10 degree intervals. The mean global cloud cover data are presented as contours of cloud fraction and were obtained from three sources: (1) International Satellite Cloud Climatology Project (ISCCP); (2) the Atlas of Surface Marine Data 1994; and (3) the Global Distribution of the Total Amount of Cloudiness.
