Cache AirTrack presents the most recent PM2.5 and temperature data from the Cache Valley and is color coded to the AQI scale. Click on the graphic for current air quality trends.
Logan, Utah is a bucolic mountain valley 
town in Northern Utah that is home to 100,000 residents, Utah State University, and approximately 75,000 head of cattle. The valley (Cache Valley) has long been touted for its rural setting and offerings of healthy living and clean mountain air. Unfortunately, over the last several years, air quality measurements have recorded high levels of PM2.5 pollution (particulate matter less than 2.5 microns in diameter) during episodic winter-time events. The valley’s mountain geography combined with valley snow cover can produce stagnant inversions that trap pollutants during periods of high pressure.
DAQ is using a computer model to simulate the interaction of emissions from automobiles, home heating, and other sources to understand how PM2.5 is formed during winter inversions. The model will help state and town officials construct strategies that will reduce the formation of the unwanted pollutant.
