2. A composite state of a physical system that is determined by the overall configuration of many microstates; e.g. the heat of a substance (mesostate), which is made up of the aggregate of motions of many molecules (microstate).
3. A description of an aspect of a geographical system at a level between complete detail (the microstate) and a simple summary statistic or percentage (the macrostate).
4. An intermediate metabolic product in the formation of anastates or catastates.
