Status of NIWA NDACC UV-vis stations:

•Kiruna (67.8N), ceased in April 2010, archived from July 1996

•Moshiri/Rikubetsu (44.4N), archived from April 1991- December 2007, instrument status probably ok but need more time to quality-check and process.

•Mauna Loa (19.5N), failed on 1 March 2008, was replaced with a new instrument (NO2 and BrO) on 28 April 2009 until present; occasional small hick-ups.

•Lauder (45.0S), archived from Dec 1980, quality check and processing up-to-date.

•Macquarie Island (54.5S), quality check and processing up-to-date., proposal to AAD (for logistics support) highly likely successful to continue measurements.

•Arrival Heights (77.8S), archived since 1991, quality check and processing up-to-date

Future of NIWA NDACC UV-visible stations & research:

•Currently very uncertain – funding will be substantially reduced from July 2012 onwards.

•What does this mean? Best case scenario: measurements continue without any support until any problems arise …. Worst case: feel free to use your imagination

•MAX-DOAS seen as very low priority in NIWA’s science interests and will most likely at this stage not further be supported.
