Smoke from the fires burning in the Pacific Northwest continues to be observed over the Northwestern states and even further over the Great Lakes and East Coast as observed by lidars in Baltimore in the past few days. Today's image from our lidar is presented below (left). HMS team also reported smoke over Central California from fires in Southern California (top, right).
High AOD values were retrieved by MODIS Terra (bottom, left) over Montana and Canada, correlating to the very high PM2.5 levels (unhealthy to hazardous levels) reported by AIRNow (bottom, right). Similar conditions were also observed in Washington, where the fires are located but clouds hindered satellite observations.
