Eureka Stratospheric Ozone Lidar (SOLID)

The Eureka Stratospheric Ozone Lidar is a five-channel lidar located at the Ridgelab of the Polar Environment Atmospheric Research Laboratory. The instrument transmits at 308 and 353 nm. It receives elastic returns at both transmitter wavelengths and inelastic returns at 332 and 385 nm (Raman scattering on nitrogen molecules), as well as 405 nm (Raman scattering on water vapour molecules). The data is collected at five-minute intervals. The instrument operates during the night time and in clear or partiality clear sky conditions. A traditional data-processing algorithm is applied to retrieve ozone vertical profiles within an altitude range of 10-45 km using backscattered signals from both elastic (308/353 nm) and Raman (332/385 nm) channels. The backscattered signals from elastic 353 nm and Raman 385 nm channels are also used to retrieve temperature in the stratosphere and mesosphere (20-80 km). Water vapour content is retrieved using 385/406 nm wavelength pair within an altitude range of 1-6 km.
