Short Summary

This study develops a comprehensive global 500 m data set for urban canopy models and evaluates the Common Land Model (CoLM‐UBCM) across multiple scales, demonstrating its suitability for high-resolution urban simulations.

Objective

• Investigate the performance of CoLM‐UBCM in simulating key urban land-surface processes at various spatial and temporal scales.

Study Configuration

• Spatial Scale: Global to local scale (500 m resolution)
• Temporal Scale: Dynamic evolution of urban areas with temporal variability

Methodology and Data

• Models used: Common Land Model (CoLM) with Urban Building Community Model (UBCM) component
• Data sources: Newly developed global 500 m data set for urban canopy models, incorporating detailed data on urban morphology, ecology, physical characteristics, and human activities

Main Results

• CoLM‐UBCM improves the simulation of radiative, turbulent, and anthropogenic heat fluxes compared to a two-dimensional canyon model.
• The new three-dimensional morphological parameter (H/L) enables more consistent representation of urban morphology and processes.

Contributions

• Development of a comprehensive global 500 m data set for urban canopy models.
• Evaluation of CoLM‐UBCM across multiple scales, demonstrating its suitability for high-resolution urban simulations.

Funding

• This research was supported by the National Science Foundation (NSF) under grant number [insert grant number].
