Below follows an alphabetic list of various collaborative, international research networks. There are two reasons for having the list: 1) It enables users to get a quick overview of existing (and previous) networks within atmospheric dispersion; 2) For those networks interested, it provides a platform for interaction and collaboration with anybody on the globe. Networks with a collaboration platform here on the Wiki are marked with the logo Image:RedPoint.gif The list should be much more comprehensive - please make additions!
