Code Orange PM2.5 in Oregon; Mexican smoke over Western Gulf of Mexico

Code Orange AQI (Unhealthy for Sensitive Groups) PM2.5 levels were reported in Klamath Falls, Oregon in the morning hours, as shown in the EPA Airnow AQI animation and in the PM2.5 concentrations timeseries (top right image, data courtesy of airnowtech.org) of selected monitoring sites. Cloud coverage hindered satellite AOD retrievals. Over the western coast of the Gulf of Mexico, NOAA HMS reports the presence of pollutant aerosols with possible light smoke/dust from likely source in the Mexican state of Veracruz particularly near San Rafael to Veracruz. The particle pollution is clearly visible in today;s NASA Aqua MODIS AOD retrievals. The NRL NAAPS AOD model predicted AOD's no greater than 0.2 in this region.
