Multiple species UV/Visible Spectrometer (SAOZ) at Sodankylä, Finland
A. Pazmino, F. Goutail (LATMOS-IPSL) and R. Kivi (FMI) – SAOZ system for NO2 and ozone operated since February 1990, upgraded with a new detector in 1995.
A. Pazmino, F. Goutail (LATMOS-IPSL) and R. Kivi (FMI) – SAOZ system for NO2 and ozone operated since February 1990, upgraded with a new detector in 1995.
P. V. Johnston and K. Kreher (NIWA) – Operating for NO2 and ozone since 1991; extended to BrO and OClO in 1997. Operations discontinued in 2012 due to budget cuts.
A. Pazmino, F. Goutail (LATMOS-IPSL) and N. Jepsen (DMI) – SAOZ system for NO2 and O3 operated since November 1991, upgraded with a new detector in 1996.
N. Jepsen (DMI) – SAOZ system for NO2 and ozone column measurements operating since September 1990. Data through 2016 archived under original PI (P. Eriksen). Measurements ceased in late 2017 when instrument was moved to Søndre Strømfjord.
T. Svendby (NILU) and A. Pazmino and F. Goutail (LATMOS-IPSL) – SAOZ NO2 and ozone system operating since September 1990. Reanalysis of data from 2013 through 2017 is completed, and data are submitted ot the NDACC data base.
A. Richter, F. Wittrock and H. Bösch (U. Bremen) – Observations of reactive trace gases in the atmosphere using UV/vis measurements of scattered sunlight. No measurements during polar night (November to Mid February). Participated in all NDACC intercomparison campaigns since 1996. Database extends back to 1995.
K. Strong (U. Toronto) — Two DOAS systems (Horiba/Jobin-Yvon/ISA Triax-180 triple grating spectrometers with thermoelectrically cooled CCD detectors). The UT-GBS is the primary NDACC instrument ("utoronto001") and is focused on zenith-sky measurements in the visible range. It was first deployed at Eureka in 1999 for spring campaigns and permanently in 2010. The PEARL-GBS is the secondary instrument ("utoronto002") and was installed in 2006. From 2006 to 2010, it made zenith-sky measurements in the visible range, and since 2011, is focused on MAX-DOAS measurements in the UV.
