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). 

B. Liley (NIWA) – System used initially at Dumont d’Urville (66.67˚S, 140.01˚E).  Aerosol profile data (5 to 35 km) available from 1994 to 1997 under PI, Steffanutti. 

R. Querel (NIWA) – Installed November 1994 by RIVM (former PI Daan Swart).  Participated in OPAL and TOPAL intercomparison campaigns with GSFC mobile lidar, LaRC microwave ozone radiometer, and ozonesondes in 1995 and 2002, respectively.  New laser installed and retrieval software updated in 2007; all data reprocessed.  Retrieving ozone from 8 to 50 km year-round (attempting to get one measurement per week).  Also retrieves aerosols (8 to 25 km) and temperature (8 to 70 km) profiles, though neither is submitted to the NDACC database.  Ownership and PI responsibilities transferred from RIVM to NIWA as of July 2017.

G. Nedoluha and R. M. Gomez (NRL), A. Parrish (U. MA), and I. S. Boyd (BC Consulting) – Retrieving profiles from 20 to 70 km from October 1992 to October 2016.  Instrument is identical to Mauna Loa system and participated in intercomparisons at Table Mountain Facility (34.4˚N, 117.7˚W) in July 1989.  Observatoire de Haute Provence (43.94˚N, 5.71˚E) in July 1992, and Lauder in April 1995.  This instrument also operated at Table Mountain Facility from July to November 1989 and from May 1990 to June 1992. A new instrument will be installed in the future.

R. Querel (NIWA) – Weekly ECC sondes (DMT) year-round since August 1986 for obtaining profiles of ozone, temperature, pressure, and winds from 0 to 32 km. Early data archived under previous PIs (Bodeker and Zeng).

J. B. Liley and M. Kotkamp (NIWA) – Measurements of the spectral distribution of UV irradiance (285 – 450 nm) using a double monochromator since December 1989 and archived since 1991.  In November 1993, the original UVL spectrometer (JYDH10), which allowed observations only in fair-weather conditions, was replaced by the UVM spectrometer (Bentham DM300).  In September 1998, the integrating sphere on this instrument was replaced by a PTFE diffuser to allow all-weather observations, including during rain.  There have been occasional periods of spectral sky radiance and spectral actinic flux observations.  The latter also may be derived from spectral irradiance measurements. Direct beam spectral UV irradiance measurements have been made since 2011 (with the UV2 spectrometer).  A variety of filter radiometers also have been used since 1992.  Information regarding specific instruments and deployments are available from the PIs.  Data through 2013 archived under former PI, McKenzie.
