Tropospheric Studies - AERONET Support
 |
The Trajectory Analysis runs are based on the trajectory code developed at NASA/Goddard Code 614 - The Atmospheric Chemistry and Dynamics Branch. This website and analyses are being generated and supplied by T. Kucsera |
Note that not all dates within this period may be available.
Currently 7-back trajectory analyses are generated twice a day (00Z and 12Z)
and two sets of images are generated:
The first set has trajectory analyses starting at four pressures levels (950 hPa, 850 hPa, 700 hPa and
500 hPa) at each of the AERONET sites - these levels correspond to altitudes of appoximately
.5, 1.5, 3, and 5 kilometers, respectively.
In addition, the second set of images (see links labeled "All_Levels") contains the above 4 levels
as well as 4 higher levels (400, 300, 250, and 200 hPa) - corresponding to approx. altitudes of
7, 9, 10, and 12 kilometers.
Kelowna Site Special Note: In early analyses products - The Kelowna site was incorrectly
situated in China - This site is actually located in Canada.
ANALYSES AVAILABILITY INFORMATION
Analyses are Available For the following Dates -7-day Analyses starting from 2000-Jan-1 --> up to about 23 days back from today's current date.
These analyses are continually being generated on a daily basis.
