Global Annual Mean Surface Air Temperature Change

warming

Format

A data frame with three variables:

  • Source The source of data: (1) GISS Surface Temperature (GISTEMP) analysis and (2) the global component of Climate at a Glance (GCAG).

  • year The year of temperature measures.

  • month The month of temperature measures.

  • day The day of temperature measures.

  • temp Combined Land-Surface Air and Sea-Surface Water Temperature Anomalies (deviations from a corresponding period, see details)

Source

Data downloaded from https://datahub.io/core/global-temp#readme

Details

For GISTEMP: Temperature Anomalies are deviations from 1951-1980 means (see https://data.giss.nasa.gov/gistemp)

For GCAG: Temperature Anomalies are deviations with respect to the 20th century average (see http://www.ncdc.noaa.gov/cag/data-info/global)
