AWI DIAL
Alfred Wegener Institute Differential Absorption Lidar

The Alfred Wegener Institute (AWI) Differential Absorption Lidar (DIAL) is a ground-based lidar system located in Ny-Alesund, Spitsbergen, as part of the Network for the Detection of Stratospheric Change (NDSC). It is a multi-wavelength lidar that measures backscatter to retrieve aerosol and ozone profiles. It uses the DIAL technique to measure ozone at 308 and 353 nm. It detects aerosols at 353 nm, 532 nm, and 1064 nm. It also detects Raman-scattered light at 607 nm. Its resolution ranges from 600 meters to 6 km, depending on altitude.
