R. Querel (NIWA) — Zenith sky DOAS, NO2 column measurements since 1991 using a scanning grating monochromator. Two units operated in parallel, one at Scott Base, one at Arrival Heights. In 1998 a MAXDOAS UV/Vis spectrometer was installed and operated in conjunction with the University of Heidelberg.

In 2005 a UV/Vis Grating CCD array spectrometer was installed for measurements of BrO and OClO. In November 2013 the spectrometer was reconfigured (wavelength region expanded) to include spectral measurements to permit NO2 retrievals. Operational data ends in 2020.  Some data archived under former PIs (Wood and Johnston).  Data through 2020 archived under final PI (Querel).
