Ozone Measurements Using the Refurbished Eureka Stratospheric Differential Absorption Lidar
The Stratospheric Ozone Differential Absorption Lidar (DIAL) located at the Polar Environment Atmospheric Research Laboratory (PEARL) in Eureka, Nunavut (80°N, 86°W) has been a powerful tool for the measurement of stratospheric ozone vertical profiles in the Canadian High Arctic since 1993. The lida...
