Home > Atmospheric Model Intercomparison Project

 
Atmospheric Model Intercomparison Project (AMIP) is a standard experimental protocol for global atmospheric general circulation models (AGCMs). It provides a community-based infrastructure in support of climate model diagnosis, validation, intercomparison, documentation and data access. Virtually the entire international climate modeling community has participated in this project since its inception in 1990.

AMIP is endorsed by the Working Group on Numerical Experimentation (WGNE) of the World Climate Research Programme, and is managed by the PCMDI with the guidance of the WGNE AMIP Panel.

The AMIP experiment itself is simple by design; an AGCM is constrained by realistic sea surface temperature and sea ice from 1979 to near present, with a comprehensive set of fields saved for diagnostic research.

This model configuration removes the added complexity of ocean-atmosphere feedbacks in the climate system. It is not meant to be used for climate changeThe term climate change is used to refer to changes in the Earth's climate. In the most general sense, it can be taken to mean changes over all timescales and in all of the components of climate, including precipitation and clouds as well as temperature. prediction, an endeavor that requires a coupled atmosphere-ocean model (e.g., see AMIP's sister project CMIP).

Atmospheric ductIn telecommunication, an atmospheric duct is a horizontal layer in the lower atmosphere in which the vertical refractive index gradients are such that radio signals (a) are guided or focused within the duct, (b) tend to follow the curvature of the Earth,Atmospheric reentryAtmospheric entry is the transition from the vacuum of space to the atmosphere of any planet or other celestial body. The term is not used for landing on bodies which have no atmosphere e. Atmospheric reentry refers to the return to an atmosphere previousAtmospheric pressureAtmospheric pressure is the pressure caused by the weight of air above any area in the Earth's atmosphere. Standard atmospheric pressure atm is discussed in the next section. Air masses are affected by the general atmospheric pressure within the mass, cre
Atmospheric waveguideAn atmospheric waveguide is an atmospheric flow feature that enhances the propagation of certain atmospheric waves. The effect arises because wave parameters such as group velocity or vertical wavenumber depend on mean flow direction and strength. Thus, fAtmospheric sciencesFluid dynamics Atmospheric sciences is an umbrella term for the study of the atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems.
