The NOAA Global Interoperability Program (GIP), initiated in 2009, supports and promotes the development of software infrastructure for a set of weather and climate applications that have been recognized as being critically important. These are:

The need for greater coordination in software infrastructure development among U.S. and international weather and climate modeling centers, as manifested in GIP, has been discussed in numerous papers and reports.[1] [2] [3] [4] [5]

Motivation and Purpose[edit]

There is increased demand for climate and weather information since the IPCC Fourth Assessment Report identified climate change as a potential hazard to human health and welfare. Much of this information relies on software infrastructure for its creation and dissemination.

The needed infrastructure includes software frameworks and other Common Modeling Infrastructure, data distribution portals, and data analysis and visualization services. These software elements have been developed by multiple agencies and organizations. Often they need to interact with each other in scientific workflows. Some software elements are used in multiple application areas, and enable these groups to leverage each others products and collaborate across disciplines.

The purpose of the GIP program is to serve as a coordination point for these infrastructure projects, to foster cross-disciplinary activities, and to improve the capabilities in each of the critical application areas by improving the base of distributed infrastructure that lies beneath them all. Participating agencies and organizations include NOAA, NASA, the National Science Foundation, the United States Department of Defense, the United States Department of Energy, European Union centers that are part of the METAFOR collaboration, and several universities.

Software Infrastructure for Weather and Climate Modeling[edit]

The table shows how tasks in the workflows of the GIP focus applications in weather and climate rely on an overlapping software infrastructure base. Where different organizations use different packages for the same task, or different conventions are used for different kinds of modeling, incompatibility issues can hinder cross-disciplinary development and collaborations.
