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. Attendees will be given the opportunity to visit the Maido Observatory which is scheduled to begin operations in early 2012.

The NDACC Steering Committee has developed a graphic to depict the measurement capabilities of the network. The chart provides a summary of the species and parameters whose measurements are archived in the DHF, the instrumental techniques employed for the measurements, and an indication of the approximate vertical resolution of the measurements. This chart, available here, will also shortly be available in the instrument area of the NDACC web pages.

The Measurements and Analyses Directory contains a complete listing of all NDACC Affiliated Measurements, both long-term and campaign, as well as a listing of the Cooperating Networks, and the Theory and Satellite Working Group Members.

NDACC established the designation of "Cooperating Network" to formalize the relationship with regional, hemispheric, or global networks of instruments that operate independently of NDACC, but where strong measurement and scientific collaboration is mutually beneficial. More information on the "Cooperating Network" Protocol is found in the "Protocols" area of the NDACC web pages.

In the Fall of 2009, five Networks signed memoranda of understanding to complete the Cooperating Network designation. These networks are:

High spectral-resolution infrared solar transmission spectra contain information about the vertical distribution of the absorbing species in the terrestrial atmosphere due to the pressure broadening of the absorption lines. This feature is being exploited in the Infrared Working Group to retrieve vertical profile information of several atmospheric trace gases, such as O3, CO, N2O, CH4, HCl, HF, HNO3, C2H6 and HCN, in addition to the total column abundances.
