Ph. Keckhut and A. Hauchecorne (LATMOS-IPSL) – Began NDACC operations in January 1991.  Database extends back to 1979.  Participated in July 1992, 1997 and 2017/2018 intercomparisons with GSFC mobile lidar.  Data from 2011 to October 2012 are of low quality and are not archived.

G. Ancellet (LATMOS-IPSL) – Began NDACC operations in January 1991. Database extends back to 1989. New lidar system installed in March 2012 (Licel electronic boards).  Participated in Aug. 1989, March 1991 intercomparison with aircraft and ozonesondes and in 2017/2018 intercomparison with GSFC mobile lidar and ozonesondes.

T. J. McGee (GSFC), L. Twigg (SSAI), and G. Sumnicht (SSAI) – The STROZ lidar retrieves ozone vertical profiles in the stratosphere from 10 to 50 km.  Temperature to ~80 km and aerosols (at 355 nm) to 35 km also are measured.  The instrument has also been modified to measure water vapor from near the ground to ~10 km.  As a mobile intercomparator, it has participated in ozone intercomparisons at OHP for July – August 1992 and for June – July 1997.

G. Ancellet and S. Godin-Beekmann (LATMOS-IPSL) – Soundings once per week since 1984: Brewer Mast (1984-1991), ECC since 1991 (SPC before 1997, ENSCI since 1997). Data archived since 1991 at NDAAC and WMO for Brewer Mast.  Participated in July 1997, 2017/2018 intercomparisons with GSFC mobile lidar and in JOSIE Juelich chamber evaluation.

A. Pazmino, F. Goutail, and J. P. Pommereau (LATMOS-IPSL) – SAOZ system for NO2 and ozone operating since June 1992, upgraded with a new detector in June 1995; NDACC intercomparisons in 1992, 1995, 1996, and 2003.  A new mini-SAOZ was installed in September 2011 for long-term comparisons with existing SAOZ to ascertain NDACC qualifications.
