            5 Getting started: a Greenland ice sheet example
            6 ==============================================
            7 
            8 This introduction is intended to be interactive and participatory, and it should work on
            9 *your personal machine* as well as on a supercomputer. Please try the commands and view
           10 the resulting files. Do the runs with your own values for the options. We can't hide the
           11 fact that PISM has lots of "control knobs," but fiddling with them will help you get
           12 going. Give it a try!
           13 
           14 We get started with an extended example showing how to generate initial states for
           15 prognostic model experiments on the Greenland ice sheet. Ice sheet and glacier model
           16 studies often involve modeling present and past states using actions like the ones
           17 demonstrated here. Our particular choices made here are motivated by the evaluation of
           18 initialization methods in :cite:`AschwandenAdalgeirsdottirKhroulev`.
           19 
           20 We use data assembled by the `Sea-level Response to Ice Sheet Evolution (SeaRISE)
           21 <searise_>`_ assessment process :cite:`Bindschadler2013SeaRISE`. SeaRISE is a
           22 community-organized assessment process providing an upper bound on ice sheet contributions
           23 to sea level in the next 100--200 years, especially for the IPCC AR5 report in 2013.
           24 
           25 This example is a hands-on first look at PISM. It is not an in-depth tutorial, and some
           26 details of what is happening are only explained later in this Manual, which thoroughly
           27 discusses PISM options, nontrivial modeling choices, and how to preprocess input data.
           28 
           29 The basic runs here, mostly on coarse `20` and `10\,\textrm{km}` grids, can be
           30 done on a typical workstation or laptop. PISM is, however, designed to make high
           31 resolution (e.g. `5\,\textrm{km}` to `\sim 500\,\textrm{m}` grids for
           32 whole-Greenland ice sheet modeling) possible by exploiting large-scale parallel
           33 processing. See :cite:`AschwandenAdalgeirsdottirKhroulev`, :cite:`Golledgeetal2012`,
           34 :cite:`Golledgeetal2013`, among other published high-resolution PISM examples.
