 - **CMIP**: The Coupled Model Intercomparison Project (CMIP) aims at better understanding past, present and future climate changes arising from natural, unforced variability or in response to changes in radiative forcing in a multi-model context. For more information, check the [WCR-Climate webpage](https://www.wcrp-climate.org/).

 - **ensemble**: An ensemble is a collection of experiments based on standardised inputs. This ensures that ensemble calculations use the same initial states, initialisation methods, and physics details. Ensemble members are named in the rip-nomenclature, *r* for realization, *i* for initialisation and *p* for physics, followed by an integer, e.g. r1i1p1.
 
-- **experiment**: An experiment is defined as an activity aimed at addressing a specific scientific problem. In CMIP, experiments are numerical experiments with climate models

 - **grid**: In the dataset section of a recipe, a grid is the array of coordinates on which a variable has been sampled.
 
 - **mask**: Masks are used to isolate regions. For example, if you apply an ocean mask, then coordinates in the ocean will not be taken into account for the preprocessors/diagnostics. Masks can also be used to work with regions that have missing or invalid entries.
 
 - **mip**: Typically used to refer to a table of variables in ESMValTool. These are standardized per project, e.g. the [MIP tables for CMIP6](http://clipc-services.ceda.ac.uk/dreq/index/miptable.html).
