NDACC recognizes the importance of new measurement capabilities and of existing capabilities whose heritage was developed external to NDACC, and has encouraged Network affiliation with such measurements. In some cases, there are regional, hemispheric, or even global networks of instruments that operate independently of NDACC, but where strong measurement and scientific collaboration would be mutually beneficial.
NDACC News and Events
At the 2008 NDACC Steering Committee meeting, a decision was made to remove the "Primary" and "Complementary" designations of NDACC measurement sites / stations. These original terminologies were instituted at the inception of the Network for designating a minimum of five stations with long-term measurement commitments, representing the major geographical regions of the globe (i.e., Arctic, Northern Hemisphere (NH) Midlatitudes, Tropics, Southern Hemisphere (SH) Midlatitudes, and Antarctic).
