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.
