In 1996, in an attempt to resolve an inconsistency between ozone profile trends obtained from satellite vs. ground-based measurements, the Stratospheric Processes and their Role in Climate (SPARC) project of the World Climate Research Programme (WCRP) initiated a collaboration with the International Ozone Commission (IO3C) to carefully re-evaluate the ground-based and satellite ozone data.

The Demonstration Network Of ground-based Remote Sensing observations (NORS) is a new EU Framework 7 R&D project in support of the GMES Atmospheric Service (GAS) that began on November 1, 2011 and will run for 33 months.
The NDACC 2012 Steering Committee Meeting will be held in Garmisch, Germany October 14–19 and will include 3 days of business, and visits to the NDACC Measurement Sites at Zugspitze and Hohenpeissenberg.
The NDACC welcomes as a Cooperating Network the Total Column Carbon Observing Network (TCCON). Though the primary data product is high precision total column CO2 several other gases are retrieved and archived as well.
The International Space Science Institute (ISSI) as issued its 2012 call for Team proposals. Details can be found at the ISSI web site.
The Baseline Surface Radiation Network (BSRN) provides near-continuous, long-term, in situ-observed, Earth-surface, broadband irradiances (solar and thermal infrared) and certain related parameters from a network of more than 50 globally diverse sites.
NDACC welcomes new UV data from the United States National Science Foundation's network of UV spectrometers operated by Biospherical Instruments Inc. The spectral UV data set from this network is one of the longest and most extensive in existence, and covers geographical areas where ozone changes have been most pronounced.
The MOHAVE-2009 campaign took place on October 11–27, 2009 at the Jet Propulsion Laboratory (JPL) Table Mountain Facility in California. This third MOHAVE campaign involved more instruments and datasets than the two previous ones held in 2006 and 2007.
An international Symposium celebrating 20 years of global atmospheric research enhanced by NDACC/ NDSC observations will be held the November 7–10, 2011 in Saint Paul, Reunion Island, France. The symposium is being organized by the Observatoire de Physique de l'Atmosphere de la Reunion.
Despite its low abundance in the atmosphere, stratospheric bromine contributes up to 25% to the global ozone loss due to its high ozone depletion potential. The main sources of bromine in the stratosphere are natural and anthropogenic long-lived and very short-lived brominated organic compounds.
