R. Querel (NIWA) — Zenith measurements of NO₂ and ozone. Database extends back to 1980 using a grating scanning monochromator; BrO/OClO since 1995 using a CCD array; direct sun from 2001; MAXDOAS from 2004. Early data through 2012 archived under previous PI (Johnston).

A. Pazmino, F. Goutail (LATMOS-IPSL) and G. Held (UNESP) — SAOZ system for NO₂ and ozone operating since November 1995; upgraded with a new detector in February 2001.

A. Pazmino and F. Goutail (LATMOS-IPSL) — SAOZ system for NO₂ and ozone operating since July 1993; upgraded with a new detector in 1997.

Y. Kondo (Tokyo U.) and W. A. Matthews (NIWA) – NIWA system for NO₂ and ozone operated from August 1994 to 1998.

R. Querel and A. Thomas (NIWA) — DOAS, measuring trace gases from global and scattered irradiance, since 1996. Current measurements, since late April 2009, of NO₂ and BrO slant columns are made using a CCD detector. Spectrometer damaged in early 2014 and returned to Lauder. Measurements are unlikely to continue. Data up to 2009 are archived under previous PI (Johnston). Data from 2009–2013 not yet archived.

P. V. Johnston (NIWA) — NIWA system for NO₂ and ozone operated beginning mid-1995. Measurements ceased in May 1999 due to a computer failure.

A. Pazmino, F. Goutail (LATMOS-IPSL) and P. V. Johnston (NIWA) — SAOZ system measuring NO₂ and ozone operated from July 1992 – July 1999.

M. Navarro Comas (INTA) — NO₂ and ozone data using a scanning spectrometer. Archived under former PIs from 1993–1999  (Yela), 2000–2013 (Gil), and continues with current PI. Instrument participated in the 1996 OHP intercomparison. Also retrieves column abundances of ozone, H₂O, and O₄.

Y. Kondo (U. Tokyo) and P. V. Johnston (NIWA) – Measurements of NO₂ and ozone were made at the Observatory from 1992 to 1996.

V. Sinyakov (KNU) — Morning and evening NO₂ measurements since 1983. Participated in 1997 intercomparison at Zvenigorod.
