The ''' Time-Varying Microscale (TVM) model ''' is a [[microscale]] [[diagnostic model]] specifically designed to compute data for extremely high-resolution mapping (tens of meters to a few hundred meters) without the high computational costs of running a [[mesoscale]] [[Numerical Weather Prediction]] (NWP) model such as [[Weather Research and Forecasting model]] (WRF).

TVM uses high-resolution [[land surface]] data to calculate the effects of microscale terrain features, near-surface roughness features, and other terrain blocking effects typically left unresolved by coarser mesoscale NWP models. Microscale terrain features are resolved using a [[Kinematics|kinematic]] terrain adjustment, near-surface roughness features are resolved using a log-profile surface roughness adjustment, and a [[Froude number]] adjustment is applied to calculate terrain-blocking effects on wind flow.

All of these effects are computed at each [[time -step]] in the study period and based not only on [[wind speed]] and [[elevation]], but also on quantities such as [[wind direction]] and thermodynamic properties of the lower [[atmosphere]],. This enablingenables a sophisticated time-varying [[spatial analysis]].<ref>{{Cite web|url=http://www.3tier.com/en/support/glossary/#tvm|title=Glossary of Technical Renewable Energy Terminology :: Support :: 3TIER}}</ref>
