NO2 concentrations scale as a power law with population (exponent 0.14-0.22) and inversely with distance from center (exponent -0.12 to -0.18), combining into a radial profile proportional to (N/r)^0.16 across European cities.

Cross-sectional urban scaling exponents generally do not reflect the growth trajectories of individual cities but arise from statistical patterns across diverse city histories, as illustrated by the area-population relation.
Intra-urban temperature and air pollution variability collapses onto general scaling functions characterized by average street network properties across 142 cities.
