What does this program measure?
Stratospheric Ozone profiles (15-55km),
How does this program work?
The experiment uses high-power, ultraviolet lasers. The laser wavelengths 308 and 353 nm are transmitted into the atmosphere. Radiation back scattered by the atmosphere at these wavelengths and also at 332 and 385 nm from atmospheric nitrogen Raman scattering is monitored. Ozone is measured by differential absorption lidar (DIAL), temperature by Rayleigh and Raman lidar, and aerosols by elastic backscatter (Mie) lidar. Observations occur 3-4 times per week at MLO.
Why is this research important?
The primary goals are to make the earliest possible identification of changes in the ozone layer and to discern the causes of the changes; to provide an independent calibration of satellite sensors of the atmosphere, and to obtain data that can be used to test and improve multidimensional stratospheric chemical and dynamical models.
Are there any trends in the data?
