NOTICE: EFFECTIVE SEPTEMBER 26, 2007
The
Trajectory Tool has been modified to
include the following six enhancements:
-
Addition of pop-up labels to
identify the monitoring sites.
-
Trajectory run time can now be
specified in 5-minute increments.
-
The map zoom feature has been
improved.
-
The trajectory position labels
increase in size to display
uncertainty in location as a
function of time.
-
The user has the option to export
the calculated 5-minute trajectory
positions to a comma-delimited ASCII
text file.
-
The user has the option to email a
trajectory to another user.
Use of the above features is
demonstrated in the newly updated
Trajectory Tool Tutorial.
Any questions or comments on the
enhancements or use of the Trajectory
Tool should be directed to
Gary McGaughey.
Use the Trajectory Tool to calculate and display a forward
or backward trajectory over a street
level map of the Corpus Christi area.
What is a trajectory?
A trajectory represents the hypothetical path of a
near-surface air parcel assuming the
parcel moves with the area-averaged
winds measured by the Corpus Christi
network of surface monitoring stations.
Simply put, the trajectory provides an
estimate of the path air traveled.

trajectory and a summary of the
