Editing Climate model (section)

== Uses ==

There are three major types of institution where climate models are developed, implemented and used:
* National meteorological services: Most national weather services have a [[climatology]] section.
* Universities: Relevant departments include atmospheric sciences, meteorology, climatology, and geography.
* National and international research laboratories: Examples include the [[National Center for Atmospheric Research]] (NCAR, in [[Boulder, Colorado]], US), the [[Geophysical Fluid Dynamics Laboratory]] (GFDL, in [[Princeton, New Jersey]], US), [[Los Alamos National Laboratory]], the [[Hadley Centre for Climate Prediction and Research]] (in [[Exeter]], UK), the [[Max Planck Institute for Meteorology]] in Hamburg, Germany, or the [[Laboratoire des sciences du climat et de l'environnement|Laboratoire des Sciences du Climat et de l'Environnement]] (LSCE), France.
Big climate models are essential but they are not perfect. Attention still needs to be given to the real world (what is happening and why). The global models are essential to assimilate all the observations, especially from space (satellites) and produce comprehensive analyses of what is happening, and then they can be used to make predictions/projections. Simple models have a role to play that is widely abused and fails to recognize the simplifications such as not including a water cycle.<ref>{{Cite book |last=Trenberth |first=Kevin E. |url=https://www.cambridge.org/core/product/identifier/9781108979030/type/book |title=The Changing Flow of Energy Through the Climate System |date=2022 |publisher=Cambridge University Press |isbn=978-1-108-97903-0 |edition=1 |chapter=Chapter 1: Earth and Climate System |doi=10.1017/9781108979030}}</ref>
