Cloud Seeding Experiment (Winter Only)


Rainfall amounts from a cloud seeding experiment (winter only)


A data frame with 28 observations on the following 7 variables.

Seeded Treatment coded as S=seeded or U=unseeded
Season All in Winter
TE Rainfall in East (treatment)
TW Rainfall in West (treatment
NC Rainfall in North (control)
SC Rainfall in South (control)
NWC Rainfall in Northwest (control)


Researchers were interested in whether seeded clouds would produce more rainfall. An experiment was conducted in Tasmania between 1964 and 1971 and rainfall amounts were measured in inches per rainfall period. The researchers measured the amount of rainfall in two target areas: East (TE) and West (TW). They also measured the amount of rainfall in three control locations. Clouds were coded as being either seeded (treatment) or unseeded (control). This is a subset (only Winter months) of the larger CloudSeeding2 dataset. All rainfall amounts are in inches.
