Compression by densification

Description

Amount of compression of a depth increment for linear densification of firn with a constant rate.

Usage

Compression(z1, z2, rate)

Arguments

z1	initial depth of the depth increment.
z2	final depth of the depth increment in the same units as z1; must be larger than z1.
rate	constant rate of firn densification relative to the surface density; in inverse units of z1.

Details

The compression is calculated based on the assumption of conservation of mass and assuming that densification leads only to a compression of a firn parcel in vertical direction and not to any stretching in horizontal direction.

Value

the relative compression of a depth increment when transported from depth z1 to depth z2 in dimensionless units.
