Ozone

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.

S. Godin-Beekmann (LATMOS-IPSL) — Began NDACC operations in January 1991. Database extends back to 1985. New lidar system installed in January 1994. Participated in July 1992, 1997 and 2017/2018 intercomparisons with GSFC mobile lidar and sondes.

M.-R. De Backer-Barilly (GSMA Reims) and G. McConville (NOAA/ESRL) — Total ozone and Umkehr database using Dobson instrument #085 extends back to 1983.

J. de La Noë and N. Schneider (Bordeaux) — Profiles from 25 to 70 km obtained on a year-round basis since January 1995.  Ceased operations in mid-2003.

J. de La Noë (Bordeaux) – Daily Dobson #49 observations beginning in 1985, but previously carried out at Biscarosse (60 km from Bordeaux) from 1976 to 1983.  Instrument moved to Observatoire Midi-Pyrénées/Lannemezan in September 2004.  Data archived for 1996–2003.

R. Stübi (MeteoSwiss) and H. Schill (PMOD/WRC Davos) — Daily Dobson #101 observations until 2014, Dobson #062 after. The Dobson has been fully automated since 2014. Data begin in July 1926, archived since 1990. This instrument moved to Davos in February 2021. Data through 2013 archived under previous PI (Viatte).

Eliane Maillard Barras and G. Romanens (MeteoSwiss) — Observations with Brewer Mast ozonesondes three times per week beginning November 1966, then ECC since September 2002. Data archived since 1990. Data through 2013 archived under previous PI (Viatte). Data from 2014 to 2021 archived under previous PI (Stübi).

E. Maillard Barras and A. Haefele (MeteoSwiss) — Deployed from January 2000 to June 2002 in Bern (46.95˚N, 7.45˚E, prior to permanent siting at Payerne. The SOMORA instrument provides ozone volume mixing ratios between 20/25 and 65 km with a 1-hour time resolution. Data through June 2019 are archived under previous PI Ruffieux.

A. Murk (U. Bern) — Volume mixing ratio profiles (20 to 70 km) since November 1994 at Bern.  Site is 60 km from the Jungfraujoch.  Intercompared with Payerne, Switzerland (46.8˚N, 7.0˚E) ozonesondes.  In the long-term future, this instrument will be replaced.  A new instrument is operating on a regular basis in Payerne. Early data archived under previous PI Kämpfer.

W. Steinbrecht (DWD) — Ozone sondes since 1967.  One launch per week before 1978; 2 to 3 launches per week since 1978.
