Abstract : This effort continued assembling the still available measurements from selected nuclear and large chemical explosion clouds. This empirical data base both helps interpret model predicted effects and validate the predictions.The test were selected after screening many events for data completeness of both the inputs and outputs for the DICE/MAZ and TASS hydrocodes. These are used to calculate the rise and stabilization of the fireball and cloud. The effort's focus was the particles in the dust dominated and water/ice dominated clouds.This report discusses some archive searches, the limitations of further comparisons of adaptively gridded outputs with measurements, and simultaneous gas and dust measurements in the 10 June 1993 event, MINOR UNCLE. The dust and ANFO by-products were characterized between 0.5 and 2.5 hr after burst by making 10 or more passes at two altitudes in the severely sheared cloud. The repeated passes are used to get good data on radial diffusion behavior in the free troposphere, which can also be used for statistically validating model outputs.
