Rollback to a Standard. Start by clicking on the Create Air Quality Grids button, and
choosingMonitor Rollback. On the Monitor Rollback Settings: (1) Select Monitors
window, select your pollutant (Ozone) and year (2000), and click Next. On the next window,
click theAdd Region button and enter 10 for the Percent. In the previous example, we used
theSelect All button to include all states in the rollback region. In this example we want to
create three regions instead, so just click on the three western-most states to add them to the
region. The states you have added to the region will turn yellow, as in the picture below.
To add states with a second type of rollback, click on theAdd Region button, choose the
rollback type, and then click on the counties to include in this second region, which BenMAP
denotes asRegion 2. In this example, we have chosen an Incremental Rollback of 5 and a
background of 20, and applied it to the 14 next western-most states.
The map now depicts two rollback regions. We can toggle back and forth between each region
by clicking on the legend on the left side of the map. Any counties that have not yet been
included in a region may be added to an existing region, or we may create one or more regions
for these remaining counties. Note that once counties have been included in a rollback region,
they cannot be included in a different rollback region. In our example, the three western-most
states are highlighted in gray.
