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.
NDACC News and Events
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.
