The NDACC recognizes that there are important regional, hemispheric, or even global measurement and analysis networks that operate instruments independently of NDACC, but where strong measurement and scientific collaboration is mutually beneficial. Designation of an interested external network as a “Cooperating Network” fosters the desired collaborative measurement and analysis activities through mutual data access and mutual steering group representation, yet retains the independence of each network.
More information on the Cooperating Network Protocol is found in the "Protocols" area of the NDACC web pages.
Information about each Cooperating Network can be found at the descriptive links, or at the Network external webpages as listed below.
