GISTEMP

Surface air temperature change is a primary measure of global climate change. The GISTEMP project started in the late 1970s to provide an estimate of the changing global surface air temperature which could be compared with the estimates obtained from climate models simulating the effect of changes in atmospheric carbon dioxide, volcanic aerosols, and solar irradiance. The continuing analysis updates global temperature change from the late 1800s to the present.

地表气温变化是全球气候变化的首要度量指标。自20世纪70年代末开始，GISTEMP项目旨在提供全球地表气温变化的估计值，这些值可与模拟大气二氧化碳、火山气溶胶和太阳辐照度变化效应的气候模型所得估计值进行比较。持续的分析更新了从19世纪末至现今的全球温度变化。
