The Evolution of Temporal and Spatial Patterns of Carbon Monoxide Concentrations in the Metropolitan Area of Sao Paulo, Brazil

Table 4

Regression equation for CO concentration (CO), temperature (), relative humidity (), and wind speed (). and value refer to the regression equation. An alternative regression equation is calculated when a variable coefficient does not have a 95% confidence interval.
