Description

Rainfall amounts from a cloud seeding experiment

Format

A dataset with 108 observations on the following 8 variables.

Period ID for time period
Seeded Treatment coded as S=seded or U=unseeded
Season Coded as Autumn, Spring, Summer, or 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)

Details

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). A subset (only Winter months) of these data is stored in CloudSeeding. All rainfall amounts are in inches.
