Evaluating Practical Performance of Weather Modification Aerosol Catalysts via 12000 m³Artificial Climate Chamber

The lack of experimental tools to evaluate the deicing performance of newly developed weather modification agents hinders their further development. Here, for the first attempt, the largest artificial climate chamber in Asia (volume = 12000 m³) was employed and successfully generated freezing rains. As a result, deicing properties of modified aerosol catalysts could be revealed both qualitatively and quantitatively. It was found that 96.98% of the formed glaze icing was inhibited and transformed to snow after applying the catalyst. Such an artificial climate chamber may be applicable for evaluating new weather modification agents without the need for field experiments.
