Global Temperature Time Series. Data are included from the GISS Surface Temperature (GISTEMP) analysis and the global component of Climate at a Glance (GCAG). Two datasets are provided: 1) global monthly mean and 2) annual mean temperature anomalies in degrees Celsius from 1880 to the present.

Data

Description

Combined Land-Surface Air and Sea-Surface Water Temperature Anomalies [i.e. deviations from the corresponding 1951-1980 means]. Global-mean monthly […] and annual means, 1880-present, updated through most recent month.

Global temperature anomaly data come from the Global Historical Climatology Network-Monthly (GHCN-M) data set and International Comprehensive Ocean-Atmosphere Data Set (ICOADS), which have data from 1880 to the present. These two datasets are blended into a single product to produce the combined global land and ocean temperature anomalies. The available timeseries of global-scale temperature anomalies are calculated with respect to the 20th century average […].

Additional Data

Upstream datasets: GHCN-M ERSST ICOADS

Other: HadCRUT4 time series data are not included in the published Data Package at this time because of the dataset’s restrictive terms and conditions. However, the data preparation script supports processing the dataset.



Preparation

Requirements

Data preparation requires Python 2.

Processing

Run the following script from this directory to download and process the data:

make data

Hundredths of degrees Celsius in the GISTEMP Global Land-Ocean Temperature Index data are converted to degrees Celsius.

A HadCRUT4 processing script is available but not run by default.

Resources

The raw data are output to ./tmp . The processed data are output to ./data .
