livvkit — Ice Sheet Validation

The livvkit task runs LIVVkit (Land Ice Verification and Validation Toolkit) for ice sheet model evaluation. It compares climatology files generated by the climo — Climatology Files task against reanalysis datasets.

Parameters

Parameter	Required	Default	Description
active	No	False	Set to True to enable this task.
climo_subsections	No	[""]	List of [climo] subtasks to depend on.
cfg	No	"inclusions/livvkit/livvkit_r05.jinja"	Path to the LIVVkit configuration template.
icesheets	No	"gis,ais"	Icesheets to analyze: gis (Greenland), ais (Antarctica).
sets	No	"cmb,smb,energy_racmo,energy_era5,energy_merra2,energy_ceres"	Validation sets to perform.

Climo dependency requirements

The livvkit task requires specific [climo] subtasks to be defined:

• A grid-native climatology must be generated, assumed to be named land_monthly_climo_native.

• For each reanalysis comparison, a corresponding land_monthly_climo_GRID subtask is needed, where GRID is the reanalysis grid name.

Available reanalysis comparisons and their grid names:

• racmo_gis, racmo_ais

• merra2

• era5

• ceres (uses the default CMIP6 grid)
