            1 This directory contains scripts testing PISM's behavior in the "ice
            2 slab warming reversibility" experiment created by Thomas Kleiner.
            3 
            4 This setup is described in *Enthalpy benchmark experiments for
            5 numerical ice sheet models* by **T. Kleiner, M. Rückamp, J. H.
            6 Bondzio, and A. Humbert**, see *experiment A* in
            7 www.the-cryosphere.net/9/217/2015/

            9 In short: a 1000 m thick slab of ice rests on a flat bed and is
           10 subject to Dirichlet boundary conditions at the top surface. The
           11 bottom surface boundary conditions are set by PISM depending on basal
           12 conditions.
           13 
           14 The top surface B.C. as a function of time is a "boxcar" function
           15 switching from "cold" to "warm" and then back to "cold" conditions.
           16 
           17 The steady state corresponding to the initial as well as final "cold"
           18 surface B.C. has a linear-in-depth enthalpy distribution that can be
           19 found analytically.
           20 
           21 We expect PISM to be able to "cool down" after a warm period,
           22 returning to the original model state.
