Wider impact and conclusions
With the integration of icclim within ocgis, a wider distribution and use of the package is envisioned, especially through NCAR/NCPP. icclim/climate4impact will also be used within the FP7-SPACE CLIPC European project with the addition of climate indicators calculations, and potentially also in some other France National projects.

Description of work
Within the FP7 European projects IS-ENES/IS-ENES2 on European climate model data infrastructure, a web portal tailored for climate change impact communities is being developed, called climate4impact. A first prototype version has been released in 2013, and a second release is expected in April 2014. It features static and dynamic documentation, Use Cases and best practice examples, a search interface, an integrated authentication and authorization system with the Earth System Grid Federation (ESGF), a visualization interface (ADAGUC).
To support the impact communities, a generic package (icclim) to calculate climate indices (starting with the ECA&D indices) is currently being developed. Several constraints had to be considered: full memory integration with the climate4impact WPS (pyWPS); fast performance for near-realtime on-the-fly calculations, notably with the integration of icclim within NCAR/NCPP OpenClimateGIS (ocgis) which features OpenDAP time and spatial subsetting as well as data chunking, but also through the optimization of the code using an integrated python C shared-library. icclim also ensures that NetCDF output files are CF-compliant and preserves existing MetaData. It also provides MetaData information on the data processing.
