Climate Open Data

Our database contains climate data from numerous sources. Most of this data is monthly and annual data with some data collected daily. This data is sourced directly from the referenced websites without any modification. Check the versions of the data as they are frequently recalculated and updated.

Be aware that the anomaly data from different sites use a different baseline. For a great comparison of this data with a common baseline, check out http://www.woodfortrees.org/notes

As well as the data source sites listed below, other sites also analyse climate data, typically without any prejudgement. These include:

• WUWT - Watts up with that ?
• Wood for the Trees
• Dr. Roy Spencer
• Climate 4 You
• Schlumberger Excellence in Education Development

Our database only contains climate data back until 1650. While data earlier than this has not been included, its importance in understanding Climate Change is critical. Our Paleo Climate page expands on some of the key data found in ice cores, etc.
