To see a specific graph please specify the parameters to the right. The default view within the index banded graphs is a colour background which matches the index system of Low (Index 1,2 or 3), Moderate (Index 4,5,or 6), High (Index 7, 8 or 9) or Very High (Index 10). Only the pollutants that have been assisgned an index band can be plotted within this section. Therefore some pollutants measured at certain stations may appear to be "missing". To view these pollutants please click the link below for the Base Data Graphs where all pollutants are available for graphing.
Alternatively, see the Current Readings page for today's measurements - again. you are presented with the option to view the banded data or base data.
