Trajectories initiated on the coordinates of the dust layers observed by David Tratt with the JPL 10.6-micron lidar on April 27, 29, and 30, 1998 flow back to China within 5 to 9 days.
These are our 10.6-micron lidar backscatter profiles for the week of April 27. They show the coarse evolution of the dust cloud as it appeared over the lidar site in Pasadena, Calif. More detailed interpretation and comparisons against correlative data are in process.
Last Monday (April 27), the new aircraft (CONVAIR 580) of the CAR Group made a test flight over Cheeka Peek (NW tip of the Olympic Peninsula, WA) area around noon local time. During the ascent to 4.1km, the plane sampled an aerosol layer that it is believed to have originated from the large dust storms that occurred in China during the last week.
I was in the process of taking sun photometer measurements during April 17 through 29 in Reno for a measurements class. Although I dont't have complete coverage over that time period I did measure high AOT starting on April 25 in the range 0.3 to 0.5 at 525 nm. For more information and a summary of the data if anyone is interested.
This is a list of web links that I use to check out the global daily aerosol situation. I have been doing that since about February 98. Sofar it has been a truly aerosol-rich season. SeaWiFS is absolutly mmmarevelous - a digital camera snapping color pictures of the world daily! I know this list should be better annotated ...but I wanted to share it while I still have people's attention :). Am I missing any good on-line aerosol weather links?
