Abstract
DURING the early part of this year, the nocturnal atmospheric emission in the near infra-red (to 15 microns) has been observed at College, Alaska, using a standard Perkin–Elmer single-pass monochromator with a rock-salt prism and thermocouple detector. The instrument was directed toward the southern sky, at about 20° above the horizon, giving an optical path of about four air masses.
