CanAM4 model output prepared for CMIP5 amip, served by ESGF

'amip' is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5

( https://pcmdi.llnl.gov/mips/cmip 5). CMIP5 is meant to provide a framework for coordinated

climate change experiments for the next five years and thus includes simulations for

assessment in the AR5 as well as others that extend beyond the AR5.


3.3 amip (3.3 AMIP) - Version 1: AMIP (1979 - at least 2008). Impose SSTs and sea ice from observations but with other conditions as in experiment 3.2 historical.

The Lagrangian tendency of a quantity is its rate of change following the motion of the fluid, also called the "material derivative" or "convective derivative". The Lagrangian tendency of air pressure, often called "omega", plays the role of the upward component of air velocity when air pressure is being used as the vertical coordinate. If the vertical air velocity is upwards, it is negative when expressed as a tendency of air pressure; downwards is positive.[CF-Standard Name]; unit: Pa s-1

cf:Mass fraction is used in the construction mass_fraction_of_X_in_Y, where X is a material constituent of Y. It means the ratio of the mass of X to the mass of Y (including X). A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. Riming is the rapid freezing of supercooled water onto a surface. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes).
