The past two days have seen a noticeable increase in wildfire smoke and the associated decrease in air quality. Here at ISU on the top of Agronomy Hall, we have a Purple Air air quality sensor and the IEM has started a recent ingest of this sensor's data. The featured chart presents the daily range between the best and worst PM2.5 Air Quality Index (AQI). The colorized ranges are based on the AQI Basics found on the airnow.gov website. The chart shows the creep into the unhealthy category over the past few days. Air quality is expected to improve on Wednesday as wind directions shift. At the moment, you can't find much tooling for this data on the IEM website. There is only a crude download option.

Good = 16
