On this R-data statistics page, you will find information about the CloudSeeding2 data set which pertains to Cloud Seeding 2. The CloudSeeding2 data set is found in the Stat2Data R package. You can load the CloudSeeding2 data set in R by issuing the following command at the console data("CloudSeeding2"). This will load the data into a variable called CloudSeeding2. If R says the CloudSeeding2 data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the CloudSeeding2 R data set. The size of this file is about 4,464 bytes.

Cloud Seeding 2

Description

Rainfall amounts from a cloud seeding experiment

Format

A dataset with 108 observations on the following 8 variables.

R project statistics dataset table

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.
