atmospheric window

(window)
(frequency bands within which the atmosphere passes EMR)

An atmospheric window is a band of frequencies or wavelengths for which the Earth's atmosphere allows electromagnetic radiation to pass (given that the Earth's atmospheric transparency is limited). To other wavelengths, the atmosphere is opaque. Some atmospheric windows:

There are narrower windows as well, such as the water hole, which allows the 18-cm and 21-cm line to be viewed from the ground.
