About the graph

The colours in this graph describe each pollutant's air quality status. The station's index is determined by the highest or worst pollutant. Not all pollutants are measured at each site.

Data for a given 24-hour period is available twice daily, 35 minutes after 9 am and 5 pm. Data may be unavailable after this time due to instrument errors and power interruptions and the like. Such data is shown in the table as NA.

The time shown in this graphs is Central Standard Time (CST). This is done to be consistent with all other NEPM air monitoring data. When viewing the graphs, simply add an extra hour during daylight saving time. For example, graphs produced in the morning end at 9.00 am (8.00 am CST).
