Global-average temperature data released
The Met Office has today released station temperature records for over one and a half thousand of the stations that make up the global land surface temperature record.
This data is a subset of the full HadCRUT record of global
temperatures, which is one of the global temperature records that
have underpinned IPCC assessment reports and numerous scientific
studies. The data subset consists of a network of individual
stations that has been designated by the World Meteorological
Organisation for use in climate monitoring. The subset of stations
is evenly distributed across the globe and provides a fair
representation of changes in mean temperature on a global scale
over land.
This subset is not a new global temperature record and it
does not replace the HadCRUT, NASA GISS and NCDC global
temperature records, all of which have been fully peer reviewed.
This subset shows that global average land temperatures have risen
over the last 150 years and is very similar to the temperature
rises shown by the complete dataset.
This subset release will continue the policy of putting as much of the station temperature record as possible into the public domain. As soon as we have all permissions in place we will release the remaining station records - around 5000 in total - that make up the full land temperature record. We are dependant on international approvals to enable this final step and cannot guarantee that we will get permission from all data owners.
We intend that as soon as possible we will also publish the specific computer code that aggregates the individual station temperatures into the global land temperature record.
UEA fully supports the Met Office in making this data publicly available and is continuing to work with the Met Office to seek the necessary permission from national data owners to publish, as soon as possible as much of the data that we can gain permission for.
