  2. IDEA MODIS PM2.5 AQF (http://idea.ssec.wisc.edu/) 04/23/06 (Sunday) 04/23/06 (Monday) Elevated MODIS AOD values seen over the East Pacific Ocean during the past 3 days suggest that the latest in a series of pulses of Asian dust is located just off the West Coast, with yet another pulse beginning to cross the central Pacific (GOES-10 split window difference animation | Navy NAAPS).
