Random Error Propagation Analysis in the Plume Diagnostic Code EMABIC

摘要

The formal theory of linear error propagation is applied to the data smoothing and profile inversion routines of the plume diagnostic code EMABIC. In addition to the normal operation of retrieving the radial temperature and concentration profiles of the plume from measured transverse profiles of emission and absorption, EMABIC can now automatically estimate the accuracy of retrieval from estimates of the experimental random error of the measurements. An application of the method is made for a case previously examined with an empirical error propagation method. The present results are essentially in agreement with those of the previous study.
