6/29/2015 Wenatchee Air Quality Improves

Wenatchee air quality has improved significantly from the early morning hours and the category is now "Moderate". Technical tidbit: those with particularly sharp eyes may notice that some of the bars on the chart below (especially around 6-8 am) do not match the values on the chart in the previous post. Why not? It's because the most recent values in these charts are estimates of a 24-hour average that tries to predict into the future. So as actual monitoring values come in, the 24-hour averages are updated and become more accurate.
