Profile - multiple species

E. Mahieu (U. Liège) — A Bruker 125HR with 258cm maxOPD started operation in September 2024.

I. Morino (NIES) - The measurements with a commercial Bruker IFS 120HR in the observation room of the Climate Change Research Hall at NIES and original solar tracker started in May 2001. This was used mainly for near infrared measurements (TCCON) but NDACC measurements with filters #1 - #3 were also performed. The 120HR was replaced by 125HR in April 2010 and NDACC measurements with filters #1 - # 4 started. The measurements with filter #5 and #6 started in January 2014. Total columns and vertical profiles of the standard NDACC 10 species as well as HCHO, OCS, NH3, C2H2, and NO2 using SFIT4 are archived since 2014. The results for some species are also archived since 2010.  Instrument NDACC Affiliated September 2022.

M. Frey (IMK-ASF), U. Raffalski (IRF), and F. Hase (IMK-ASF) — Bruker 120HR (0.002 cm 1 resolution) operated since 1996. It is fitted with four detectors for both solar and lunar measurements. Intercompared with the NPL travel instrument in March 1998. Remote control capability exists since 2004. Upgraded to Bruker 125 in 2007.

D. Smale and J. Robinson (NIWA) — Trace gas profiles beginning in 1996 with a Bruker 120M (400–4000 cm 1 range, 0.0035 cm 1 resolution). A Bruker 125HR (400–4000 cm 1 range, 0.0035 cm 1 resolution) was installed in November 2014 and operated in parallel with the Bruker 120M. Intercomparisons between the two instruments occurred over the Austral Summer seasons 2014–2015 and 2015–2016) with the retirement of the Bruker 120M in February 2016. From 1991–1995 measurements were taken using a Bomem DA2 (0.02 cm 1 resolution) and an Eocom (0.06 cm 1 resolution).

D. Smale and J. Robinson (NIWA) — Bruker 120M (400-4000 cm‑1 range, 0.0035 cm‑1 resolution) operating August 1990 to September 2001; Bruker 120HR (400–4000 cm-1 range, 0.0035 cm‑1 resolution) from October 2001 to May 2018. Bruker 125HR (400-4000 cm‑1 range, 0.0035 cm-1 resolution) operating November 2017–present. Intercomparisons between the 120HR and 125HR instruments occurred from November 2017 to May 2018. Prior to the Bruker 120M installation, campaign measurements were made in 1986–89 with a Bomem DA2 (0.02 cm^-1 resolution).

N. Jones and D. Griffith (U. Wollongong) — Operations since 1994. Instruments include a Bomem DA3 (0.02 cm 1 resolution) from December 1994 to May 1996, a Bomem DA8 (0.004 cm 1 resolution) from May 1996 to January 2008, and a Bruker HR 125 (0.004 cm 1 from January 2008 to present.

M. De Mazière (IASB-BIRA) — Bruker 125HR installed in March 2013 for NDACC measurements.

M. De Mazière (IASB-BIRA) – Bruker 125HR installed in 2011, mainly for TCCON measurements but provides NDACC measurements as needed.

M. De Mazière (IASB-BIRA) – Bruker 120M operating on a campaign basis since 2002, archiving beginning in 2004. Installed in 2009 for quasi-permanent operation until end of December 2011.

J. Hannigan and I. Ortega and M. Coffey (ret) (NCAR) — Measurements resumed in 2009 with a new automated system operating older U. Denver Bruker 120HR (250cm OPD). In 2011 the instrument was upgraded to a Bruker 125HR (data lapse March 2010-August 2011). In 2017 a new automated observations system was installed.
