Air Quality Indices (AQI) peaked this afternoon in the Code Orange (Unhealthy for Sensitive Groups) range across the San Joaquin Valley in California. Elsewhere, Code Yellow (Moderate) AQIs were experienced in the Pacific Southwest, Central Plains and sporadically throughout the Southeast, Great Lakes, and Mid- Atlantic (top left). The area of concentrated fires in the Central Plains (Iowa/Nebraska/North Dakota) may have contributed to the elevated AQIs experienced there (top right). It appears the smoke layer associated with fires burning in Central America has dispersed, as it is no longer detected by the HMS analysis team. In terms of satellite imagery, MODIS suggested elevated aerosol optical depth (AOD) over western Texas, although there is no clear indication of smoke in this region (bottom).
