Welcome to the JPL Table Mountain Atmospheric Lidar Group Website


The JPL TMF Atmospheric Lidar Group, part of JPL's Laboratory Studies And Atmospheric Observations Group (329H), has been designing, building and operating several lidar instruments dedicated to the long term monitoring of atmospheric composition and satellite validation for over two decades.

A Differential Absorption Lidar (DIAL) has been routinely measuring stratospheric ozone and middle atmospheric temperature from the JPL-Table Moutain Facility (TMF) 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 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 more generally, atmospheric composition changes and their role on climate. The tropospheric ozone lidar measurements also contribute to the North-American Tropospheric Ozone Lidar Network (TOLNet).

Furthermore, JPL TMF hosts the website for the NDACC Lidar Working Group.
