| Term: | Porosity |
| Definition: |
The fraction of any given volume not occupied by solid matter, and therefore available for occupation by fluids such as air and water. In snow and firn the porosity is nearly equal to 1 /i, where is the density of the dry snow or firn and i the density of ice. IHPGlacierMassBalance
