5 Glossary

column
A column is a single atmospheric column corresponding to a lat-lon point or grid cell. The column physics works on atmospheric columns.

data dycore
A data model that replaces a dynamical core with methods that read the required dynamics state variables from input datasets and possibly does time interpolation of the input data.

dynamical core
The algorithm used to solve the atmospheric equations of motion. Referred to as a ``dycore.''

dynamics package
An implementation of a dynamical core.

history file
A history file is output that records atmospheric variables for a particular time period.

module
Modules correspond to Fortran 90 modules. Modules are composed of data and procedures (methods), and provide encapsulation, i. e., access to the data and methods can be controlled.

package
A package is an independently testable coding unit. Packages are composed of modules.

package interface
A package interface is the specification of use for a package. It includes the procedures for initializing and calling the package as well as the description for the log, history and restart mechanisms within the package.

restart file
A restart file is output that records atmospheric model's state at a particular time for use in restarting the model from that point.
