water lines
(spectral lines specific to water)
Water lines (spectral lines) in astrophysics fall under
at least two classifications:
Water absorption, like that of many compounds,
produces many lines affecting significant bands of the spectrum,
The presence of water vapor in extra-solar planet atmospheres can
be detected by transmission spectroscopy through
recognizable water lines.
Water vapor's presence in Earth's atmosphere significantly limits
microwave, millimeter, submillimeter, and
infrared observations from the ground, motivating observations
from space as well as from high, dry ground locations.
