Estimating biogenic CO₂ fluxes is essential to quantify urban anthropogenic emissions, yet urban vegetation heterogeneity presents a significant challenge to making accurate estimations. The authors have developed an hourly temporal, 10‐m spatial resolution biogenic CO₂ flux estimation framework based on the Vegetation Photosynthesis and Respiration Model (VPRM) and its variants (UrbanVPRM and VPRM‐modified). Unlike lower‐resolution models, their approach captures finer‐scale variability, particularly in fragmented urban green spaces like street trees and lawns.
