China Meteorological Stations Quarterly Temperature Interval Dataset

Description

Interval-valued temperature data (Celsius) for 60 Chinese meteorological stations observed over the four quarters of years 1974 to 1988. One outlier observation (YinChuan_1982) has been discarded.

Usage

data(china_temp.int)

Format

A symbolic data frame (symbolic_tbl) with 899 observations and 5 variables:

• Q1: Quarter 1 (Jan–Mar) temperature range (tenths of degrees Celsius, interval).

• Q2: Quarter 2 (Apr–Jun) temperature range (interval).

• Q3: Quarter 3 (Jul–Sep) temperature range (interval).

• Q4: Quarter 4 (Oct–Dec) temperature range (interval).

• GeoReg: Geographic region classification (factor).

Details

Originates from the Long-Term Instrumental Climatic Database of the People's Republic of China. Widely used in the SDA literature for demonstrating standardization, clustering, self-organizing maps, MLE and MANOVA.
