| The JPL atmospheric lidar group (part of JPL section 3282/Atmospheric Observations) has been designing, buliding and operating for over two decades several lidar instruments dedicated to the long term monitoring of atmospheric composition and satellite validation. |

| 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 2005 respectively. The long-term high quality measurements from these four lidars contribute to our understanding of our changing planet, in particular processes governing stratospheric ozone depletion and climate change. |
