5.3.2 Temporal Scaling

Temporal scaling involves both a Base Year Model File and a Future Year Model File, and

scales the concentrations of each neighboring monitor by the ratio of the modeled concentration

at the grid cell containing the monitor in the future year to the modeled concentration at the grid

cell containing the monitor in the base year. This approach takes into account what the air quality

modeling reveals about the changes in pollution levels over time at the monitor sites. For

example, if the modeling forecasts that in the future, pollution levels will decrease, then the scaling

will result in multiplying the monitor values with a ratio less than one, and thus produce lower

forecasts at the grid cell than would be obtained with the unscaled monitor data.

Temporal scaling, then, is useful because monitors cannot provide any information about future

conditions. Model data can provide this information, which can then be used to project future

monitor concentrations.
