| Popis: | This synopsis of the investigation over the frequency interval of 58 to 62 kMc of emission and absorption of the earth's atmosphere between sea level and 100 thousand feet describes the measurements of the earth's atmosphere and simulated atmospheres and the results of the data analysis. The attenuation and emission of the atmosphere was found to be described within the limits of atmospheric variability by previously derived empirical equations. Between sea level and 100 thousand feet the attenuation between 58 and 62 kMc at the line center frequencies and between the line center frequencies has average values of 200 db and 145 db, respectively. The emission temperature into space from 100 thousand foot altitudes is 220°K between the lines and 225°K at line center frequencies. The emission temperature is a function of bandwidth and within the variability limits of the atmosphere, independent of incident solar radiation. |
