The proposal from the Australian Bureau of Meteorology for NDACC affiliation for four Dobson measurements was discussed and approved at the 2017 NDACC Steering Committee Meeting in Boulder, Colorado. The measurements were formally invited as NDACC Affiliated shortly thereafter. The four sites are Darwin (12°S), Brisbane (27°S), Melbourne (38°S) and Macquarie Island (55° S). Total ozone records at Brisbane, Melbourne and Macquarie Island began in 1957.
The resolution from the International Association of Meteorology and Atmospheric Sciences (IAMAS) was released on November 22, 2017. This resolution specifically stresses the importance of continuation and enhancement of Earth Observation systems to monitor the atmosphere, ocean and other elements of the Earth system. It therefore strongly supports the effort of the NDACC steering committee, associated networks and data PIs to provide high quality and long-term observations for monitoring of atmospheric composition.
The annual meeting of the international Steering Committee (SC) for NDACC was held from October 17 to 21 in Bremen, Germany at the University of Bremen Guesthouse 'Teerhof'. Justus Notholt of the University of Bremen hosted the meeting.
2016 marks 25 years of successful operations of NDACC for enabling and enhancing global atmospheric research. A comprehensive review article commemorating this anniversary appears in the September-October 2016 issue of NASA’s Earth Observer Newsletter. The newsletter is a bi-monthly publication that consolidates NASA Earth Science news and has a readership of more than 6000 internationally.
A global network of stations using Dobson and Brewer spectrophotometer have been monitoring the status of the ozone layer during several decades. Corresponding calibration systems have been developed to ensure the good and constant data quality in this network, which enables the scientific society to detect the depletion of the ozone layer and the Antarctic ozone hole in the 80ties. One World Dobson Calibration Center (WDCC) at NOAA (Boulder) and five Regional Dobson Calibration Centers (RDCC) in the corresponding WMO Regional Associations use standard Dobsons for this purpose.
