|---|---|
| U1 | Grid average 2 m air temperatures could be used with high-resolution urban digital surface models, if available. This would allow downscaling or assessment of the likely impact of micro-scale variability of urban form (e.g. openness or sky view factor) on air temperature. |
| U2 | Input data for micro-scale modelling of urban climate. |
| U3 | Upstream background concentrations to be used together with local scale air quality modelling, allowing a more detailed description of air pollution levels. |
| U4 | Flood risk and water balance assessments |
| U5 | Solar resource assessment models, detailed urban solar radiation models, building energy models. |
