  skos:definition """LYMAN-ALPHA HYGROMETER is a hygrometer based on the absorption
of radiation by water vapor at the Lyman-alpha line, which is an
emission line of atomic hydrogen at 121.567 nm; this radiation
can be generated by a glow discharge in hydrogen and detection
is accomplished by a nitric oxide ion chamber; Lyman-alpha
hygrometers are typically used on aircraft and meteorological
towers for high frequency humidity measurements."""@en ;
