Reports & guidance
The UKCP09 climate projections have been compiled into five main scientific reports, all of which can be downloaded from the UKCP09 Published Reports table below: the Briefing report, the Observed trends report, the Climate projections report, the Marine and coastal projections report and the Weather Generator report. The Observed trends extremes atlas is also available here.
In addition a series of Technical Notes are available that provide technical information about certain aspects of the UKCP09 projections. These are available in the Technical Notes table below.
Further guidance on using the observed trends, climate change projections, marine and coastal projections, weather generator, 11-member Regional Climate Model (RCM) and Spatially Coherent Projections can be found using the links on the left of the page.

Briefing report (June, 2009)
The Climate of the United Kingdom and Recent Trends (Observed trends) report contains information on observed climate trends in the UK, to provide an historical context for the future climate change projections. Maps and graphs are available for many of the same variables that appear in the UKCP09 projections.
For guidance on material in this report see About the Observed Trends .
Observed trends report (January 2009)
For guidance on material in this report see About the Climate Change Projections.
Climate Projections report (version 2, July 2009)
The Marine and Coastal Projections report provides a set of scenarios that may be used to assess how vulnerable particular sites or sectors are to future climate change. The report considers the marine environment from the coastal zone and into the waters of the shelf seas around the UK.
For guidance on material in this report see About the Marine and Coastal Projections.
Marine and Coastal Projections (June 2009)
The Weather Generator Report explains the principles behind the Weather Generator, explains how it can be used and contains maps of illustrative changes in future extremes across the UK.
For guidance on the Weather Generator and the Threshold Detector see About the Weather Generator.

This technical note on Storm Projections summarises the information available on storms in UKCIP02, UKCP09 and selected other sources. Different publications can define storms differently and so readers must be clear how a storm is being defined.
This technical note on Probabilistic Wind Projections presents probabilistic projections of changes in 30-year mean wind speeds relative to 1961-1990.
This technical note shows the changes from the original Weather Generator, using Tables 3 and 4 from the Weather Generator report.

This technical note explains the validation of the Weather Generator.

This technical note provides an analysis of the variability introduced by the Weather Generator compared to that generated by the probabilistic projections.

This technical note presents projections of lightning from the 11-member RCM.
|This technical note presents projections of snow from the 11-member RCM.|
This technical note presents fog projections from the 11-member RCM
|This technical note on surface wind speed was produced to provide information on wind speed, as such information was not available directly from the initial UKCP09 results.|
An 11-member ensemble of Spatially Coherent Projections (SCPs) has been generated to support those users who need to consider climate change at more than one location in a way that captures the relationship between the different locations.
Guidance on the Spatially Coherent Projections is available here.
