Land-Ocean Temperature Index, 1880-2022

Description

These data contain monthly mean temperature anomalies expressed as deviations from the corresponding 1951-1980 means. They are useful for showing how we can measure climate change.

Usage

LOTI

Format

A data frame with 1,716 observations on the following 2 variables.

date

a date, mostly to contain information for the year and month

value

the mean temperature anomaly as deviation from corresponding 1951-1980 mean

Details

Data are updated through most recent month, at least for last time I updated it. Data represent combined land-surface air and sea-surface water temperature anomalies. Of note: the day value in the date column has no real value. It was just a way of combining data that are aggregated by year and month.
