Line 2: ==History and Evolution== The CF conventions were introduced in 2003, after several years of development by a collaboration that included staff from U.S. and European climate and weather laboratories .<ref>{{cite news \| author = Gregory, Jonathan \| year = 2003 \| title = The CF metadata standard \| url = http://cf-pcmdi.llnl.gov/documents/other/cf_overview_article.pdf }}</ref>. The conventions contained generalizations and extensions to the earlier Cooperative Ocean/Atmosphere Research Data Service (COARDS) conventions <ref>{{cite web\|url=http://ferret.wrc.noaa.gov/noaa_coop/coop_cdf_profile.html\|title=Conventions for the Standardization of NetCDF files\|date=May, 1995}}</ref> and the Gregory/Drach/Tett (GDT) conventions .<ref>{{cite web\|url=http://www-pcmdi.llnl.gov/drach/GDT_convention.html\|title=GDT netCDF conventions for climate data, version 1.3\|date=March 14, 1999}}</ref>. As the scope of the CF conventions grew along with its user base, the CF community adopted an [[open governance]] model .<ref>{{cite news \| author = Lawrence, B.N. \| year = 2003 \| title = Maintaining and Advancing the CF Standard for Earth System Science Community Data \| url = http://cf-pcmdi.llnl.gov/documents/white-papers/cf2_whitepaper_final.html }}</ref>. In December 2008 the trio of standards, netCDF+CF+OPeNDAP, was adopted by [[IOOS]] as a recommended standard (number 08-012) for the representation and transport of gridded data. The CF conventions are being considered by the [[NASA]] Standards Process Group (SPG) and others as more broadly applicable standards <ref>{{cite news \| author = Rew, Russ \| year = 2010 Line 18: \| url = http://www.esdswg.org/spg/rfc/esds-rfc-021/ESDS-RFC-021-v0.01.pdf }}</ref> .<ref>{{cite news \| author = Domenico, Ben \| year = 2009 \| title = Web Coverage Service (WCS) 1.1 extension for CF-netCDF 3.0 encoding \| url = http://xml.coverpages.org/OGC-09-018-WCS11-ExtensionCF-netCDF.pdf }}</ref>. ==Applications and User Base== The CF conventions have been adopted by a wide variety of national and international programs and activities in the Earth sciences .<ref>[http://cf-pcmdi.llnl.gov/projects-and-groups-adopting-the-cf-conventions-as-their-standard Projects and Groups Adopting or Encouraging the CF-Conventions as a Standard]</ref>. For example, they were required for the [[climate model]] output data collected for [[Coupled model intercomparison project]]s, which are the basis of [[Intergovernmental Panel on Climate Change]] assessment reports .<ref>{{cite news \| year = 2009 \| title = Report of the 12th Session of the JSC/CLIVAR Working Group on Coupled Modelling (WGCM) \| url = http://wcrp.ipsl.jussieu.fr/Documents/WMP/136_WGCM12.pdf }}</ref>. They are promoted as an important element of scientific community coordination by the [[World Climate Research Programme]] .<ref>{{cite news \| author = Kinter, James L. III \| year = 2005 Line 41: \| title = Issues Related to the Dissemination of Climate Model Output \| url = http://wcrp.ipsl.jussieu.fr/Documents/WMP/Presentations/WMP1_2-7Taylor.pdf }}</ref>. They are also used as a technical foundation for a number of software packages and data systems, including the Climate Model Output Rewriter (CMOR), which is post processing software for climate model data, and the [[Earth System Grid]], which distributes climate and other data .<ref>{{cite news \| author = Doutriaux, Charles \| year = 2010 Line 55: \| title = NetCDF in ArcGIS 9.2 \| url = http://www.crwr.utexas.edu/gis/gishydro06/Introduction/Presentations/netCDF.ppt }}</ref>. The CF conventions have also been used to describe the physical fields transferred between individual Earth system model [[software components]], such as atmosphere and ocean components, as the model runs .<ref>{{cite journal \| doi = 10.1007/s12145-008-0016-1 \| author = Dunlap, R.

However, the CF conventions are also applicable to many classes of [[observational data]] and have been adopted by a number of groups for such applications. ===Supported Data Formats=== CF originated as a standard for data written in [[netCDF]], but its structure is general and it has been adapted for use with other data formats. For example, using the CF conventions with [[Hierarchical Data Format]] data has been explored .<ref>{{cite news \| author = Yang, M., R. Duerr, C.
