In the lowermost layer of the atmosphere—the troposphere—ozone is an important source of the hydroxyl radical, an oxidant that breaks down most pollutants and some greenhouse gases. High… Expand
Temperature climatology of the middle atmosphere from long‐term lidar measurements at middle and low latitudes
Long-term measurements from several lidar instruments (Rayleigh and sodium) located at 44.0°N, 40.6°N, 34.4°N, and 19.5°N have been used to develop a new climatology of the middle atmosphere… Expand
Halogen Occultation Experiment ozone channel validation
The HALogen Occultation Experiment (HALOE) instrument on UARS observes vertical profiles of ozone and other gases of interest for atmospheric chemistry using the solar occultation technique. A… Expand
Tropical stratospheric aerosol layer from CALIPSO lidar observations
 The evolution of the aerosols in the tropical stratosphere since the beginning of the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) mission in June 2006 is… Expand
Accuracy of Raman lidar water vapor calibration and its applicability to long-term measurements.
A Raman lidar calibration method adapted to the long-term monitoring of atmospheric water vapor is proposed. The accuracy of Raman lidar water vapor profiles is limited by that of the calibration… Expand
Ozone differential absorption lidar algorithm intercomparison.
An intercomparison of ozone differential absorption lidar algorithms was performed in 1996 within the framework of the Network for the Detection of Stratospheric Changes (NDSC) lidar working group.… Expand
Evaluation of optimization of lidar temperature analysis algorithms using simulated data
Temperature lidar data have been simulated in order to test the Jet Propulsion Laboratory (JPL) SO3ANL version 3.2 and Service d'Aeronomie du Centre National de la Recherche Scientifique (CNRS/SA)… Expand
Validation of Aura Microwave Limb Sounder Ozone by ozonesonde and lidar measurements
We present validation studies of MLS version 2.2 upper tropospheric and stratospheric ozone profiles using ozonesonde and lidar data as well as climatological data. Ozone measurements from over 60… Expand
Long-term evolution of upper stratospheric ozone at selected stations of the Network for the Detection of Stratospheric Change (NDSC)
 The long-term evolution of upper stratospheric ozone has been recorded by lidars and microwave radiometers within the ground-based Network for the Detection of Stratospheric Change (NDSC), and by… Expand
Sodium lidar–observed strong inertia‐gravity wave activities in the mesopause region over Fort Collins, Colorado (41°N, 105°W)
 In December 2004, the Colorado State University sodium lidar system at Fort Collins, Colorado (41°N, 105°W), conducted an ∼80-hour continuous campaign for the simultaneous observations of… Expand
