The '''ESMF''' (''Earth System Modeling Framework''' ('''ESMF''') is [[open source software]] for building [[climate]], [[numerical weather prediction]], [[data assimilation]], and other [[Earth science]] [[software applications]]. These applications are computationally demanding and usually run on [[supercomputers]]. The ESMF is considered a technical layer, integrated into a sophisticated [[common modeling infrastructure]] for [[interoperability]]. 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>
