In addition to the HYSPLIT model, the Soybean Rust Aerobiology
Prediction System (SRAPS) was created as an application of
the Integrated Aerobiology Modeling System, or IAMS (31). Initially
created to predict introduction potential of important invasive
plant pathogens, IAMS uses large, archived meteorological data
sets to determine potential P. pachyrhizi deposition events. The
model uses disease-monitoring observations on the SBR-PIPE, and
daily predicts where spores will be deposited. Predicted spore
depositions are mapped and uploaded onto the restricted website to
be used by university extension specialists (30,32). This model was
used to further support the notion that SBR inoculum likely arrived
in the continental United States in association with Hurricane Ivan
