Summary and Conclusions <br />

• Introduced physically-­‐based roughness sublayer <br />

parameteriza6on <strong>in</strong>to CLM <br />

• Generally improves CLM’s surface flux predic6ons when tested <br />

<strong>in</strong> offl<strong>in</strong>e mode <br />

• Need to iden6fy mechanisms responsible for stomatal <br />

shutdown (i.e., overly high leaf temperatures). <br />

• Next steps: <br />

- Coupled mode <br />

- With<strong>in</strong>-­‐canopy transport <br />

- Reac6ve chemistry (VOCs)
