Appendix H.  Plots of trajectories for the worst visibility days for the Virgin Islands National Park 2000  -  2004.

In EPA's docket for the Virgin Islands Federal Implementation Plan, there are snapshots of the trajectories described in Appendix F.  Here is a list of the files: the snapshot jpeg files are listed in the docket and each begins with the letter `H' in the docket. The KMZ files are not in the docket  -  see below for how to get these files from EPA.

.kmz files are available from EPA, in order to see the trajectories more easily.  The kmz files can be seen in the publically available Google Earth program. Contact kelly.bob@epa.gov to get a set of the kmz files.
The next page has the list of the days that EPA modeled with trajectories. It is the same list as Table 3-4 in the FIP and in Appendix F.
