A Differential Absorption Lidar
(DIAL) has been routinely measuring stratospheric ozone and middle
atmospheric temperature from the JPL-Table Moutain Facility since 1988.
Another DIAL system has been operating at the Mauna Loa Observatory,
Hawaii since 1993. A tropospheric ozone DIAL and a water vapor Raman
lidar also located at Table Mountain have been operating since 1999 and
The long-term high quality
measurements from these four lidars contribute to the database of the
international Network for the
Detection of Atmospheric Composition Change (NDACC) to understand
our changing planet, in particular processes governing stratospheric
ozone depletion and climate change. The tropospheric ozone lidar
measurements also contribute to the US-based Tropospheric
Ozone Lidar Network (TOLNet).
