Modern electronic aerosol instruments such as the scanning mobility analyzer or the aerodynamic particle sizer provide size information at much higher resolution than older impactors or optical particle counters do. Whereas an impactor may span a decade of particle diameter with two or three stages, an aerodynamic instrument may do so with 25-30 channels and a scanning mobility spectrometer with 64 channels. Whether or not the channels represent real particle size discrimination, comparison of data between high- and low-resolution instruments would be made easier if the data resolution could be made comparable. Moreover, the problems of converting mass concentration measurements to number concentrations (and vice versa) would be facilitated if there were high resolution size bins to use for computations, rather than having to rely on some average size to represent all the particle sizes within a size band. We present here an interpolation method for redistributing coarse histogram data into finer size bins without compromising the original data and including information gleaned from experience with multiple aerosol measurements. It is based upon a simple smoothness criterion and can be implemented in many computer spreadsheet programs. |
