Given a warning based on detection of hazardous materials at just a few sensors, it could be useful to rapidly (minutes)
provide an estimate of the source location, time of release, and amount of material released. Such an estimate can lead to refined
predictions of the area impacted by the hazardous release, and can support near-term follow-on actions to investigate the cause and
nature of the hazardous release. In September 2007, a short-range, highly-instrumented test was conducted at the U. S. Army’s
Dugway Proving Ground. This test, referred to as Fusing Sensor Information from Observing Networks (FUSION) Field Trial 2007,
or simply FFT 07, was designed to collect data to support the further development of source term estimation algorithms. This
presentation describes how the field trial data collected during FFT 07 is being used for investigating several prototype algorithms
including the goals of the comparisons, the comparison protocol, and the design of the comparative evaluation matrix
