After the success of the DRIHMS project and while it was still ongoing, the DRIHMproject, October 2012 also saw the activation of the DRIHM2US project, which aimed to expand the European technology network in the United States to promote scientific collaboration on hydrometeorological research issues on both sides of the Atlantic Ocean.
The final objective of the project, which ended in October 2014, was applied research for the implementation of complex models aimed at predicting extreme events and understanding whether they are related to climate change. The USA has top-level centralized computing resources and has always been at the forefront of hydrometeorological research. DRIHM2US aimed to promote cooperation between scientific communities, the use of US computing resources by European researchers and the sharing of results, data and models studied.
DRIHM2US had the collaboration of CIMA Research Foundation and the Ludwig Maximilians Universitaet in Munich, Germany, the Institute of Applied Mathematics and Information Technology of CNR, the Consortium of Universities for the Advancement of Hydrologic Science (CUAHSI) in the USA, Stichting Deltares in the Netherlands, HR Wallingford in the UK and the National Center for Atmospheric Research (NCAR) in the USA.
