NDACC News and Events
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 Data summaries through November 2009 have been archived for most sites in the NDACC database.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.
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.
