J. Notholt, and M Palm (U. Bremen) — Bruker 120M through 2013, updated to 125M electronics in 2013. Maximum resolution 0.005 cm‑1. Continuous measurements and archiving since 2004. Also typically make one or two campaigns per year. Retrieval with SFIT2, SFIT4 and GFIT.  Instrument failed in 2024.

M. Grutter de la Mora and W. Stremme (UNAM) — Measurements performed routinely with a Bruker 120/5HR (0.0035 cm-1) acquired from DLR and upgraded by KIT-IMK in 2011. The instrument was installed in May 2012 at the Altzomoni Observatory, a high altitude station located in Central Mexico at 3,985 masl. Retrievals are performed with PROFFIT.

M. Schneider (KIT-IMK) and O. Garcia (AEMET) — Measurements performed using a Bruker 120M (0.0035 cm-1 resolution) since February 1999. Replaced with a Bruker 125HR (0.0035 cm-1 resolution) in 2005.

T. Nagahama (STEL) and I. Morino (NIES) — Bruker 120M (0.004 cm 1 resolution) installed by STEL in May 1995. Tested at Toyokawa (35°N, 137°E) from December 1994 to April 1995. Bruker 120/5HR (0.0035 cm-1 resolution) installed by NIES in 2013. Total column data prior to 2000 is archived under previous PI (Kondo). Operations suspended from mid-2010 to 2013.

K. Strong (U. Toronto) — Bomem DA8 (0.004 cm-1 resolution) installed October 2001; routine measurements since May 2002.

T. Nagahama (STEL) — Bruker 120HR (0.0028 cm 1 resolution) operating at the Observatory since April 1996. The instrument experienced sun tracker failures from April 2007 to June 2009 and again in late 2010.  Not currently operational. NDACC measurements were scheduled to resume in mid-2015 with a Bruker 125HR.  However, no data have been archived and measurements ceased in September 2016. The instrument was scheduled to be moved to ISEE in Nagoya. Total column data from 1996 to 2000 archived under former PI Kondo , and vertical distribution data from 1996 to 2007 archived by Y. Nagahama (NIES).

E. Mahieu (U. Liège) — A Bruker 120HR with 5m maxOPD has been in regular operation since 1994. Remote control of this instrument was implemented in October 2008. This instrument was decommissioned at the end of July 2024.

P. Demoulin (U. Liège) — A home-built FTS with 2m maxOPD operated from 1984–2008.  Data from this instrument are being reprocessed and archived for the 1989–2008 time period.

J. Notholt  and M. Palm (U. Bremen) — Bruker 120HR operated from 2000-2003, Bruker 125HR since 2004. Data archived since 2002. Maximum resolution 0.0028 cm 1. Typically make one or two observations per week. Retrieval with SFIT2, SFIT4, and GFIT. The flat surroundings are conductive to satellite validation. The FTIR observations are complemented by DOAS measurements.

M. Makarova (SPbU.) – Measurements using a Bruker IFS 125HR (resolution up to 0.002 cm-1) began in 2009. The observation site is located in a suburb of greater St. Petersburg.  Retrieval algorithms: SFIT4 (V.0.9.4.4), PROFFIT 9.6. Ancillary atmospheric observations include those made using a UV/Vis. spectrometer, a microwave radiometer, and an aerosol lidar (ceilometer). Measurements affiliated with the Aerosol Robotic Network (AERONET) are also conducted.
