Miller, A. J., Shaw, D. E., Veitch, L. G., and Smith, E. J. (1979). Analyzing the results of a cloud-seeding experiment in Tasmania. Communications in Statistics - Theory and Methods, A8 (10), 1017-1047.

The data was recovered from the Statlib datasets directory.

Analysis

The analysis of Miller et al (1979) used regression techniques and permutation tests.

The rainfalls are definitely non-normal. It is interesting to estimate a transformation or distribution for the measurements.
