ENES was launched in 2001. Upon the establishment of the network and in the following years, several institutions including university departments, research centres, meteorological services, computer centres, and industrial partners, agreed to work together and cooperate (see Memorandum of Understanding) to discuss strategies to accelerate progress in climate and Earth system modelling and understanding. It is intended to be a portal for the climate modelling community, but also for all the communities interested in using climate models results. In particular the ENES portal provides access to a specific interface dedicated to the communities working on impacts of climate change.
