Variability of biomass burning aerosol optical characteristics in southern Africa during the SAFARI 2000 dry season campaign and a comparison of single scattering albedo estimates from radiometric measurements

A priority network utilizing a common bus coupled to a plurality of priority seeking peripheral devices wherein a processor or any number of processors is connected to the common bus. Each successive peripheral device is connected to the common bus in increasing priority order, such that each device will have a unique priority defined. Each peripheral device is provided with an associated peripheral control unit. Each of the peripheral control units is connected in serial fashion on an enabling line with the output of the higher priority control unit providing an enabling input to the next lowest priority peripheral control unit, such that the highest priority device requesting bus access prevents all lower priority devices from gaining access to the common bus until the higher priority device has completed its data transfer.
