The ESMF collaboration had its roots in the [[Common Modeling Infrastructure]] Working Group (CMIWG), an unfunded, [[grass roots]] effort to explore ways of enhancing collaborative Earth system model development. The CMIWG attracted broad participation from major weather and climate modeling groups at research and operational centers. In a series of meetings held from 1998 to 2000, CMIWG members established general requirements and a preliminary design for a common [[software framework]].

In September 2000, the NASA Earth Science Technology Office (ESTO) released a solicitation that called for the creation of an ESMF. A critical mass of CMIWG participants agreed to develop a coordinated response, based on their strawman framework design, and submitted three linked proposals. The first focused on development of the core ESMF software, the second on deployment of Earth science modeling applications, and the third on deployment of ESMF data assimilation applications. All three proposals were funded, at a collective level of $9.8M8 million over a three-year period. As the ESMF project gained momentum, it replaced the CMIWG as the focal point for developing community modeling infrastructure.

During the period of NASA funding, the ESMF team developed a prototype of the framework and used it in a number of experiments that demonstrated coupling of modeling components from different institutions. ESMF was also used as the basis for the construction of a new model, the GEOS-5 atmospheric [[general circulation model]] at [[NASA Goddard]].

As the end of the first funding cycle for ESMF neared, its collaborators wrote a Projectproject Planplan that described how ESMF could transition to an organization with multi-agency sponsorship for its next funding cycle. Major new five-year grants came from NASA, through the Modeling Analysis and Prediction (MAP) program for [[Climateclimate Changechange]] and Variabilityvariability, and from the [[United States Department of Defense|Department of Defense]] [[Battlespace]] Environments Institute. The [[National Science Foundation|NSF]] (NSF) continued funding part of the development team through [[NCAR]] core funds. Many smaller ESMF-based application adoption projects were funded in domains as diverse as [[space weather]] and [[sediment]] transport.

Also at the end of the first funding cycle, the ESMF collaborators wrote a white paper on Futurefuture Directionsdirections for the ESMF. This paper formed the basis for a proposal to [[National Science Foundation|NSF]] to combine ESMF (and other software frameworks) with data services to create a computational environment that supports an end-to-end modeling [[workflow]].
