     Chloride and sodium ion concentrations in rainwater from warm clouds seeded with a salt soapstone mixture were two to three times greater than in rain from non-seeded clouds east of Poona, India, during the 1974 summer monsoon. The warm cloud seeding experiment, begun in 1973 and studied intensively in 1974, 1976, 1979 and 1980, involved two 1600 sq. km experimental areas, each having 40 raingauges and separated by an intervening buffer (Fig. 1). Crossover randomization was used.
