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. Sites for the network span the globe to provide diverse and targeted data for use as validation sites for the GOSAT and OCO-2 CO2 observing satellites as well as monitoring the seasonal cycle and long-term evolution of CO2. The network shares common methodologies, technical issues and membership with the NDACC/IRWG.

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. Data summaries through November 2009 have been archived for most sites in the NDACC database. See http://UV.biospherical.com for other archivals.
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. The observed data are collected, processed and reviewed by the individual sites' scientists and subsequently provided to network's central data archive and dissemination center, the World Radiation Monitoring Center (WRMC), located at the Alfred Wagner Institute in Bremerhaven, Germany (AWI).
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. A Symposium web site will be available in March 2011 for registration, abstract submission, and booking. The abstract deadline is June 10, 2011.
