5.3.4 Examples

The first example presented is a

Monitor Directexample, which will provide a foundation for thefollowing

Monitor and Model Relativeexamples. Recall thatMonitor and Model Relativeairquality grid creation is exactly the same as Monitor Direct grid creation with the exception of

scaling. For additional examples with more detail, see Appendix B.

Example 1: Monitor Direct VNA Method

Default options

Consider the example at an hypothetical rural grid cell, from Section 5.2.2, where there are five

monitors at a distance of 25, 50, 100, 200, and 400 miles from the grid cell. Further, let us say

that the monitors have annual PM2.5 levels of 8, 13, 12, 18, and 15 μg/m3. Without any modelbased

scaling, BenMAP would calculate an inverse-distance weighted average of the monitor

values as follows:

Example 2: Monitor and Model Relative VNA Method

Default options

Spatial Only scaling

Assume the same monitors and monitor concentrations as above. Additionally, assume that the

grid cell model value in the base-year is 6 μg/m3, and the model values at the monitors in the

base-year are: 10, 14, 11, 17, and 15 μg/m3. (This modeling suggests that the grid cell is a lesspolluted

area than the area around the monitors.) Incorporating

Spatial Onlyscaling, BenMAPwould calculate an inverse-distance weighted average of the monitor values using the same

approach as before, with the difference being that the monitor values are scaled with the modeling

values:

n301 - n302 - n303 - n304 - n305 - n306 - n307 - n308 - n309 - n310 - n311 - n312 - n313 - n314 - n315 - n316 - n317 - n318 - n319 - n320 - n321 - n322 - n323 - n324 - n325 - n326 - n327 - n328 - n329 - n330 - n331 - n332 - n333 - n334 - n335 - n336 - n337 - n338 - n339 - n340 - n341 - n342 - n343 - n344 - n345 - n346 - n347 - n348 - n349 - n350
