The aerosol AQI was elevated into the moderate range in states lining the Mississippi and Ohio Rivers. In California, widespread moderate AQI, also due to aerosols, was seen. GASP continues to provide aerosol optical depth readings but several satellite products are struggling and have sporadic coverage. GASP left does show some elevated AOD where the AQI is elevated, although there are areas of surface reflectance artifacts. On the right below, a large dust storm is coming off the horn of Africa across the Arabian peninsula and exiting over the Red Sea.
But the real news makers for weather may be the stacked up trio of Tropical Storms including Typhoon Phailin which is a catagory 5 storm hitting India, Typhoon Nari which has a central pressure of 965 mb and Typhoon Wipha which has a central pressure of 955 mb. The latter two storms have gusts now of 55 m/s or 105 knots. Phailin had wind speeds of 155 mph making it the strongest storm to hit India since 1999. MODIS's images make the trio of storms impressive.
