This site previously used to provide web access to the gridded datasets of meteorological variables for use in climate modeling and climate monitoring. All these datasets were produced and maintained by researchers at the Met Office Hadley Centre.

The site was previously run by research staff with the primary aim of improving collaboration with fellow researchers. Therefore more information about climate monitoring and modeling can be found on the official Met

How do we know the world has warmed?

The 11 indicators below have been compiled by the Met Office Hadley Centre for this purpose. They draw on the work of over 100 scientists from more than 20 institutions and provide, in one place, a holistic view of our climate from the depths of the oceans to the high atmosphere. Each indicator is expected to be strongly correlated with surface temperatures and for each one, multiple analyses are shown. Multiple analyses indicate which features of the series are not sensitive to the exact choice of analysis method and might be considered robust features of the climate.

In the long-term, seven of the indicators are rising and four are declining. Each of the indicators is consistent with the land surface temperature records and shows long-term warming.

The indicators were published in the BAMS State of the Climate 2009 report. If you use these images please acknowledge the source as the Met Office Hadley Centre and reference:

The data are provided for documentary purposes only. If you wish to use the data in your analysis please contact the authors of the papers for the original series. Details are given in each data file. Many are publically available on the web.

  • Rising indicators
  • Air temperature over land
  • Sea-surface temperature
  • Marine air temperature
  • Sea-level
  • Ocean heat content
  • Specific Humidity
  • Tropospheric temperature in the “active-weather” layer of the atmosphere closest to the Earth’s surface

After purchasing the site in an online auction, I decided to recover some gridded data sets which had earlier been published on the site and republish them here.

In future, I will add more updated content about climatic changes and monitoring to make the site more reliable for anyone seeking information on the same.

Below are some datasets that I’ve republished on the site. Access them by clicking through the various topics.
