The AQI Program Editor (Figure 3-38) is accessed via the Configuration menu.



The AQI Program Selection section is a table with the following columns:

Program Name, e.g., CO, NO2, ozone8h

Parameter Type, e.g., 44201-- ozone, 42602--nitrogen dioxide

AQS Unit Type, e.g., parts per billion, micrograms/cubic meter

Average Interval, e.g., 001h (hourly)

Enabled--check to enable the AQI program in the row

Averaging type, rolling or block, only relevant if the average period is >1.

Averaging Direction, forward or backward, only relevant if the average period is >1.

Rounding Method, truncate or round

Decimal Positioner, number of places to the right of the decimal

Average Period, e.g., 8 hours, 24 hours

Scale Factor is the factor by which the reading of an instrument should be multiplied to give the true final value, for example, if you need to apply a multiplication factor to data for PPM to PPB conversion before comparing against breakpoints. Alternately, the pollutant levels can be defined within a program to match the units.

Percent Availability--percentage of valid data points required during the rolling average duration to mark the rolling average as valid

Use Zero Scaling--if selected, defines that a zero concentration value equals an AQI value of zero.

Use Surrogate Forecast--an estimation method that uses a combination of hourly particle concentrations from previous hours to estimate the Mid-24 average.

Use Conroy Forecast--Computed 24 hr. average using surrogate model developed by Dave Conroy

To add AQI program, click the asterisk at the bottom of the screen and enter values for an additional row. To cancel adding a program press the Tab key or the Escape key.

Each column in the table has a button that allows you to search for a row under that heading and a button to clear all filter criteria. You can change the column order by dragging the headings to a different place. You can drag a column heading above the table to change the way the information is grouped.

The AQI Level Selection section is a table with the following columns:

Pollutant Level--the upper limit on an AQI value for a particular group

Sub Index--the actual data value in units

Description and color--defaults to Good (green), Moderate (yellow), Unhealthy for Sensitive Groups (orange), Unhealthy (red), Very Unhealthy (purple), and Hazardous (maroon)

Font Color--color for text (used in AgileWeb site)

Sensitive Groups and Health Effects--describes people who are most sensitive to this level of pollution and the possible health results.

Health Advisory--advise for people at risk for this level of pollution

To add a pollutant level, click the asterisk at the bottom of the screen and enter values for an additional row. To cancel the addition, press the Tab key or the Escape key.
