An animation of the spatial patterns of the
aerosol sulfur concentrations.
Top pane - The spatial patterns of the 24-hour sulfur aerosol data collected
by UC Davis during the BRAVO study. To better show the changes in the daily
sulfur spatial patterns, the 24-hour sulfur data were linearly interpolated
between each day using a 2-hour time step. The spatial patterns were ocnstructed
by linearly interpolating between all available data on a given day.
Bottom pane - The sulfur concentrations measured at Big Bend.
An animation showing a dynamic flow simulation
of airmasses over Mexico and most of the U.S. during 8/28/1999 - 9/30/1999.
The animation contains the spatial location of all particles emitted at
a constant rate from a spatially uniform grid of sources at the surface
layer of the atmosphere. The particles have been colored based upon the
location they were released from with:
Yellow particles - from Texas
Black particles - from Mexico
Red particles - from east of Texas
Blue particles - from west and north of Texas
The transport simulation was created using the CAPITA Monte Carlo Model.
Particles were released from sources uniformly distributed over the region
about 100 km apart. Five particles were released from sources uniformly
distributed over the region about 100 km apart. Five particles were released
from each source every two hours, and tracked for five days. The calculation
of the transport of the particles was done using the wind fields generated
by the National Meteorological Center's EDAS/ETA modeling system and had
a grid resolution of ~80 km.
A subset of the above animation showing the
transport during the September 15, 1999 episode.
