ilamb — Land Benchmarking

The ilamb task runs ILAMB (International Land Model Benchmarking) to evaluate E3SM’s land component against observational benchmarks. It depends on the e3sm_to_cmip — CMIP6 Conversion task to provide CMIP-format land and atmosphere time-series files.

Parameters

These 5 parameters are specific to the ilamb task.

Parameter	Required	Default	Description
`cfg`	No	`"inclusions/ilamb/ilamb.cfg"`	Path to the ILAMB configuration file.
`e3sm_to_cmip_atm_subsection`	No	`""`	Name of the `[e3sm_to_cmip]` atmosphere subtask to depend on. Inferred as `atm_monthly_180x360_aave` if not specified.
`e3sm_to_cmip_land_subsection`	No	`""`	Name of the `[e3sm_to_cmip]` land subtask to depend on. Inferred as `land_monthly` if not specified.
`ilamb_obs`	No	`""`	Path to ILAMB observational data. Defaults to `diagnostics_base_path/ilamb_data` if empty.
`land_only`	No	`False`	Set to `True` for land-only runs (skips atmosphere dependencies).

Dependencies

Upstream (what ilamb depends on):

ts — Time Series Files – Monthly-lnd ts: required. Monthly-atm ts: optional.
e3sm_to_cmip — CMIP6 Conversion — Monthly-lnd e3sm_to_cmip: required. Monthly-atm e3sm_to_cmip: optional.

Downstream (what depends on ilamb):

None.

Dependency inference

When infer_section_parameters = True (the default), zppy will automatically determine the following if not explicitly set:

ts_land_subsection defaults to land_monthly
e3sm_to_cmip_land_subsection defaults to land_monthly
ts_atm_subsection defaults to atm_monthly_180x360_aave (for non-land-only runs)
e3sm_to_cmip_atm_subsection defaults to atm_monthly_180x360_aave (for non-land-only runs)
