Mike, I thought it also resulted in a wind bias?

@dudhia yes, it affects everything that depends on roughness length, including wind speed. |

Dave,
We can help with that. Jimy got the email from this group.

Mike,
Is there a specific person at CIEMAT for an attribution?

I think it would be Jorge Navarro.

He may want everyone listed as for the 6th order diffusion fix. Those are J. Fidel González-Rouco (UCM & IGEO-CSIC, Spain), Jorge Navarro and Elena García-Bustamante (CIEMAT, Spain). |

TYPE: bug fix
KEYWORDS: Noah-MP
SOURCE: Jorge Navarro (CIEMAT, Spain), Michael Barlage (NCAR)
DESCRIPTION OF CHANGES:
Problem:
When running Noah-MP with no urban scheme (bulk method), the roughness length in urban areas
was not used from the MPTABLE and instead was set to a bare soil value. This resulted in a high
temperature, high wind speed, and low sensible heat flux over cities.
Fix: use z0 from the MPTABLE

RELEASE NOTES:
When running Noah-MP with no urban scheme (bulk method), the roughness length in urban areas
used a bare soil value. This resulted in a high temperature, high wind speed, and low sensible heat
flux over cities. The correction uses z0 from the Noah-MP look-up table.
