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). 

T. J. McGee (GSFC), L. Twigg (SSAI), and G. Sumnicht (SSAI) – The STROZ lidar retrieves ozone vertical profiles in the stratosphere from 10 to 50 km.  Temperature to ~80 km and aerosols (at 355 nm) to 35 km also are measured.  The instrument has also been modified to measure water vapor from near the ground to ~15 km.  As a mobile intercomparator, it has participated in ozone intercomparisons at Lauder October – December 1992, March – October 1994, April 1995, September – December 2001, April 2002, June – July 2011, and April 2012.

B. Liley (NIWA) – Mobile Nd:YAG system operated extensively at Tsukuba (36.05˚N, 140.13˚E) for retrievals from 6 to 36 km; deployed at Lauder in November 1992.  Operated weekly.  Data archived under PI, Uchino, up to mid-1999 and under PI, Nagai, onward. Ceased operations in 2009.

G. Nedoluha and R. M. Gomez (NRL) and I. S. Boyd (BC Consulting) – NRL WVMS1 deployed from November 1992 to April 1993 and January 1994 to present following tests and intercomparisons at Table Mountain Facility (34.4˚N, 117.7˚W); presently retrieving from 40 to 80 km.  WVMS1 was replaced by WVMS7 in 2011.

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.
