Climate data set: Copernicus ERA5

Posted on by Stephan

Here graphs based on the climate data set created by Copernicus Programme as implemented by ECMWF, supplemented with the data from 1940 to 1978.

Regular updates. Check date in graph.
First graph is on the monthly anomalies plus a 10 year centered average.

Graph with monthly world temperature anomalies since 1940 compared to the 1991-2020 period, combined with a 10 year centered average. The 10 year average shows a steady rise from -0.7 to now +0.39. Highest anomaly reached in September 2023 with +0.9313

The yearly anomalies.

Graph with yearly world temperature anomalies starting 1940 compared to the 1991-2020 average. For period 1940-1975 it was between -0.5 and -0.8. Started to climb from that year on. For the last 8 years it's around +0.3. But 2023 is at +0,6

And the 30-year average (centered) on the monthly anomalies, what we refer to as climate signal.

Graph with 30 year centered average on world temperature anomalies compared to the 1991-2020 average. It starts at -0.66 (1963) and is now at +0.08 (2009)

And per decade.

Graph with average world temperature anomaly per decade since 1941 from Era5. From -0.67 to plus +0.23.
