The Center for Night Vision and Electro-Optics search model is extended to cover cases involving multiple observers under conditions with time-varying obscurants. We find that simulations with two levels of visibility conditions indicate that the persistence time of an obscurant and the correlation between observers are crucial parameters for determining the average time for first detection.
