  skos:definition """The Retroreflector in Space (RIS) experiment was provided by the
Environment Agency (EA) of Japan on the ADvanced Earth Observation
Satellite (ADEOS). The RIS is a 50 cm diameter passive cornor cube
laser retroreflector designed to provide data to infer the
distribution of ozone and other trace gases in the atmosphere. A
ground-based laser beam is reflected by the RIS to the ground station
and the constituent gases derived from the spectral response. A
differential type laser radar system is used to eliminate the
attenuating effects of the atmosphere.
