INFRARED ATMOSPHERIC STUDIES

Abstract

Two formerly unknown regions of atmospheric transmission, or "atmospheric windows", have been discovered by the writer in recent times. One of these is the micro-window at 6.3 microns, while the second is a window of major importance, which transmits extraterrestrial radiation from 16 to 24 microns. This report is concerned with extensions of the initial experiments. The atmospheric micro-window at 6.3 microns has been examined with grating resolution. The narrow region of transmission is characterized by ten absorption lines. The net emission of the earth's surface through the atmospheric window from 16 to 24 microns has been observationally compared with the net radiation loss through the principal window between 8 and 14 microns, and found to reach values in excess of 30 percent of the latter.
