The HyperHydro network is open to the broader scientific community for anyone who wants to cooperate in activities furthering the development of hyper resolution models. The governance structure is quite informal, with a post box and a website hosted at Utrecht University and three working groups (WGs) loosely organized around the sets of challenges laid out above.

These groups are:
- WG1: Setting up a testbed for comparing different large-scale models at different resolutions.
- WG2: Around computational challenges, including parallel computing and model component coupling.
- WG3: With the goal to think about delivering the information needed to achieve hyper-resolution (< 1 km) globally: parameter sets, model concepts and forcing.

HyperHydro aims to set up regular meetings at international symposia and conferences (e.g. EGU General Assembly and AGU Fall Meeting) to discuss progresses and set targets. Working group leads will be responsible for its impetus and progress, and we expect that results of working group activities will be reported through peer-reviewed publications. We invite all those who are interested to look on the website www.hyperhydro.org for current activities and past results and urge those who want to be on the mailing list or actively participate in one of the working groups to send an email to us (M.F.P.Bierkens@uu.nl or E.H.Sutanudjaja@uu.nl).

The meeting is on invitation only, but you are welcome to join any of the groups and attend the meeting by sending an email to the organizer.
