Multiple Species

Y. Matsumi (STEL), M. Koike and Y. Kondo (U. Tokyo), and P. V. Johnston (NIWA) — Measurements of NO₂ and ozone were made at the Observatory from March 1994 to October 1997.

A. Pazmino, F. Goutail (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.

Y. Matsumi (STEL), M. Koike and Y. Kondo (U. Tokyo), and P. V. Johnston (NIWA) — Measurements of NO2 and ozone have been made at the Observatory available from 1991 to 2008.

M. Van Roozendael (IASB-BIRA) — SAOZ system for NO₂ and ozone operated since June 1990. Upgraded with new detector (more pixels) and control system in late 1998. A MAXDOAS system has been in operation since July 2010.

R. Sussmann (IMK-IFU) — Bruker 120HR (0.0028 cm 1 resolution) operating since 1995 at Zugspitze. Remote control of measurements implemented in early 1998. An update to Bruker 125HR electronics was performed in Jan 2006. Column retrieval and a priori profile optimization fully automated. A NIR-FTIR operates nearby at Garmisch in association with the TCCON Network.

G. Vaughan (U. Manchester) – SAOZ system for NO₂ and ozone operated since 1991.  Also operated at Lerwick, UK (60.1˚N, 1.1˚E) and Aberdeen, UK (57˚N, 2˚W) during the EASOE (November 1991 to April 1992) and SESAME (February to April 1994) campaigns, respectively.  Ceased operations in May 2019 due to GPS failure.

A. Gruzdev and A. Elokhov (IAP) – Morning and evening NO₂ measurements since 1990. Hosted instrument intercomparison in September 1997.  Instrument needs repair.  No data since 2020.

M. Van Roozendael (IASB-BIRA) – Two DOAS systems (one for NO₂ and ozone, the other for BrO and OClO) operated during winter campaigns from January 1994 until March 1997, and continuously since January 1998.

A. Pazmino, F. Goutail, and J. P. Pommereau (LATMOS-IPSL) and V. Dorokhov (CAO) – SAOZ system for NO₂ and ozone operated since November 1998 (with data archived since January 2001).

A. Pazmino, F. Goutail (LATMOS-IPSL) and V. Dorokhov (CAO) – SAOZ system for NO₂ and ozone operated since December 1991, upgraded with a new detector in September 2005.
