The '''Community Earth System Model''' ('''CESM''') is a fully coupled [[Mathematical model|numerical]] [[Computer simulation|simulation]] of the [[Earth system science|Earth system]] consisting of [[Atmospheric model|atmospheric]], ocean, ice, land surface, carbon cycle, and other components. CESM includes a [[climate model]] providing state-of-art simulations of the Earth's past, present, and future.<ref name="CESM">{{cite journal |last = Hurrell |first = James W. |author2=M. M.

Strong [[ensemble forecasting]] capabilities, CESM-LE (CESM-Large Scale), were developed at the onset to control for error and biases across different model runs (realizations).<ref>{{cite journal |last = Kay |first = J.

CESM1 was released in 2010 with primary development by the Climate and Global Dynamics Division (CGD) of the [[National Center for Atmospheric Research]] (NCAR), and significant funding by the [[National Science Foundation]] (NSF) and the [[United States Department of Energy|Department of Energy]] (DoE).<ref>[https://www2.cesm.ucar.edu/models CESM: Models]</ref>
