'''Common modeling infrastructure''' refers to software libraries that can be shared across multiple institutions in order to increase software reuse and interoperability in complex modeling systems. Early initiatives were in the [[climate]] and [[weather]] ___domain, where [[software component]]s representing distinct physical domains (for example, [[ocean]] or [[atmosphere]]) tended to be developed by ___domain specialists, often at different organizations. In order to create complete applications, these needed to be combined together, using specialfor couplinginstance softwarea that[[general transferredcirculation andmodel]], that transformedtransfers data between thedifferent components. An additional challenge is that these models generally require [[supercomputers]] to run, to account for the collected data and for data analyses. Thus, it was important to provide an efficient massively parallel computer system, and the processing hardware and software, to account for all the different workloads and communication channels.<ref name=Dickinson02>{{cite journal

Active commonCommon modeling infrastructure projects include the Network Common Data Form ([[NetCDF]]) library, the Spherical Coordinate Remapping and Interpolation Package (SCRIP), the [[GFDL]] Flexible Modeling System (FMS),<ref>{{cite web|url=http://www.gfdl.noaa.gov/fms|title=Flexible Modeling System (GFDL)}}</ref> the OASIS coupler developed at CERFACS, and the multi-agency Earth System Modeling Framework ([[ESMF]]). The [[NOAA]] [[Global Interoperability Program]] is an integrative effort whose aim is to encourage coordination across such projects.

In the late 1990s and early 2000s, a series of journal papers and government reports described common modeling infrastructure as necessary to the competitiveness and evolution of the U.S. Earth science modeling community. These reports resulted in a number of new community projects. The Earth System Modeling Framework ([[ESMF]]) in the U.S. and the PRogramme for Integrated Earth System Modeling (PRISM) in Europe were two of the largest. Similar projects were initiated in related domains, including the Space Weather Modeling Framework and the Center for Integrated Space Weather Modeling in the [[space weather]] community.

The [[Earth System Modeling Framework]] (ESMF) is considered a technical layer, integrated into a common modeling infrastructure. Other aspects of interoperability and shared infrastructure include: common experimental protocols, common analytic methods, common documentation standards for data and data [[provenance]], shared workflow, and shared model components.<ref>{{cite web|url=http://cpo.noaa.gov/sites/cpo/MAPP/Webinars/2014/03-31-14/Balaji.pdf|title=Scientific Basis for Common Infrastructure|author=NOAA/CPO MAPP|date=March 31, 2014|page=15}}</ref>

In the late 2000s, the growing global interest in climate change refocused attention on the role of common modeling infrastructure in solving complex problems. Some of the specific factors that new common modeling infrastructure projects seek to address include:

* increased demand for access to [[climate model]] output and related information following the widespread dissemination of the conclusions of the [[IPCC Fourth Assessment Report]] in 2007

* the desire to model anticipated climate change impacts, often by linking together a variety of local, regional, and global models and datasets

* the exploration of weather modeling techniques and observational datasets to improve and validate climate model predictions<ref name=Palmer08>{{cite journal
