| Term: | Mass-balance gradient |
| Definition: |
The rate of change of mass balance with altitude, that is, the derivative db/dz of the mass-balance profile b (z). If mass balance varies linearly with altitude, the mass-balance gradient will be constant with z; if not, the gradient will vary with z. The mass-balance gradient at the equilibrium-line altitude is called the activity index. IHPGlacierMassBalance
