Text description of figure
There are four charts measuring CO concentrations in Napier and Hastings.
The first two charts show one-hour and 8-hour concentrations of CO (measured by air quality categories) in Napier for July and August 1998. Most measurements are “Good” or “Excellent”, although in July there were some readings for 8-hour concentrations that were only “Acceptable”.
The second two charts show one-hour and 8-hour concentrations of CO (measured by air quality categories) in Hastings between August and October 1998. Air quality was “Excellent” for all measurements.
