M&A Directory Entry

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.
