National Land Use Regression Model for NO2 Using Street View Imagery and Satellite Observations

Abstract: Land use regression (LUR) models are widely applied to estimate intra-urban air pollution concentrations. National-scale LURs typically employ predictors from multiple curated geodatabases at neighborhood scales. In this study, we instead developed national NO 2 models relying on innovative street-level predictors extracted from Google Street View [GSV] imagery. Using machine learning (random forest), we developed two types of models: (1) GSV-only models, which use only GSV features, and (2) GSV + OMI models, … Show more

“…In the spatial evaluation, model performance dropped significantly, with a daily R 2 CV score of 0.593 and an annual R 2 CV score of 0.549 (Supplementary Table S4). This result is consistent with many other LUR models, indicating that the issue of a lower spatial evaluation performance has yet to be solved (Park et al, 2020;Ghahremanloo et al, 2021;Qi et al, 2022).…”

“…In this paper, we invert the spatial and temporal concentrations of PM2.5 in the Fujian triangle using a land use regression model commonly used in academia [ 24 , 25 ]. The specific approach is: 34 monitoring stations in Fujian Province were selected ( Figure 2 ), and multiply scaled multi-scale buffer zones with different radii from 250 m to 16,000 m were established with these stations as the center of the circle, and the values of meteorology and elevation, rainfall, wind speed, population, and land use type ratio in the buffer zone were counted in GIS software and used as the independent variables; Using Spss software, a model with a fit higher than 0.90 was obtained by applying stepwise regression with the PM 2.5 concentration values of each station as the dependent variable in 2020.…”

“…The importance of weather drivers varied between locations, where zonal wind speed at 500 hpa, relative humidity, and total precipitation were among the dominant factors. It is important to note that alongside machine learning, other empirical, statistical models such as land-use regression models have also been widely employed in air quality research. …”
