Real benefits of Geoinformatics

• More usage of model results for science• More feedback to modelers

=> Improved models• More efficient retrieval of data

=> More time to do science

Opportunities for modelers (1/2)

• Join the IOOS Model Data Interoperability Google Group: http://groups.google.com/group/ioos_model_data_interop

• Join the Unstructured Grid Interoperability Google Group: http://groups.google.com/group/ugrid-interoperability

Opportunities for modelers (2/2)

• Try out the Matlab NCTOOLBOX to access CF-compliant model output:http://code.google.com/p/nctoolbox

• Give us feedback! Suggest more functionality! Toolbox is under active development
