The computational performance of RSL is critical as near surface diagnostics are all produced by it; these diagnostics should potentially be used in iterations of each tilmestep as forcing representing the local context.

This issue was moved by sunt05 from Urban-Meteorology-Reading/SUEWS#113.

natalieth would the analytical forms used in the ref below be useful for this?

I found Xuelong Chen's recent study on roughness sublayer length to be quite illuminating and comprehensive. He presents a methodical approach in deriving the model parameterisation.

This has been improved through recent updates - at least it's not a critical issue anymore.
