Postprocessed cloud radiative and microphysical output - ICON model

Postprocessed simulation output from a storm-resolving climate model over the Asian monsoon region. The data illustrates how changes to ice microphysics schemes can dramatically alter cloud-radiative heating profiles and top-of-atmosphere outgoing longwave radiation. It was produced by Sylvia Sullivan at the Karlsruhe Institute of Technology.

Use Cases

• Analyzing the sensitivity of cloud-radiative heating to ice microphysics parameterizations based on the described 'ice microphysical switches'.
• Investigating the impact of poorly-constrained ice nucleation parameters on model radiative outputs as mentioned in the description.
• Studying the relationship between ice-to-snow conversion rates and domain-mean outgoing longwave radiation in storm-resolving models.
• Evaluating the consistency of ice crystal effective radius treatment between microphysics and radiation schemes in climate simulations.
• Assessing the relative impact of vertical resolution versus microphysical uncertainties on radiative budgets in high-resolution models.

Strengths

• Focuses on a high-resolution (2 km) storm-resolving simulation, a state-of-the-art approach in climate modeling.
• Demonstrates large sensitivities, with ice microphysics switches altering upper-tropospheric cloud-radiative heating by a factor of four and domain-mean outgoing longwave radiation by 30 W m⁻².
• Explicitly simulates deep convection over the geographically specific Asian monsoon region.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
