Download or read book Atlas of Northern Hemisphere Density Between 30 and 60 Km written by Arthur J. Kantor and published by . This book was released on 1982 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mean seasonal density charts for the Northern hemisphere for 5-km increments of altitude between 30 and 60 km are presented in this report, along with estimates of the day-to-day variations around the mean seasonal values. This meets the need for a climatology of atmospheric density at constant altitudes above radiosonde levels. These charts are based on compilations of data by workers at the National Meteorological Center, NOAA, who combined data from TIROS operational vertical sounders with meteorological rocketsonde observations to produce once-weekly analyses of height and temperature fields for the Northern hemisphere at the 5, 2, 1, and .4 mb levels for the period July 1976 through April 1980.
