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.

The seventh SPARC science report on 'The Mystery of Carbon Tetrachloride' is now available! The full report helps to answer policy-relevant questions related to the global budget of carbon tetrachloride, an important ozone-depleting substance, closing the gap between emission reported to UNEP's Ozone Secretariat and those estimated from atmospheric observations.

Several members of the NDACC community were involved in the preparation of this report.

The 8th Implementation and Coordination Meeting (ICM-8) of the GCOS Reference Upper-Air Network (GRUAN) was held in Boulder, CO (25-29 April 2016). GRUAN and NDACC have had a long-standing collaboration (dating back to ICM-1 in 2009) that was further formalized by both GRUAN and NDACC becoming Cooperating Networks. NDACC scientists are playing increasingly important roles on the various GRUAN Task Teams and in the development of GRUAN Technical Documents for defining the needs and roles of ancillary measurements from other established networks such as NDACC.
