Probability Density Functions (PDFs)

Line graphs that show the relative probability of different amounts of climate change and which can be produced using the UKCP09 User Interface.

They can be produced for the Climate change projections and the Marine & coastal projections to show:

• Projected climate change or (over land areas) projected future climate
• Relative probability (of a specific amount of change)
• For one variable
• For one location
• For one time period
• For one temporal average
• For one, two or three emissions scenarios

PDFs can exported from the User Interface as images in various file formats (PDF, .ps, .png and .jpg). The underlying values can be exported as a comma-separated variable (*.csv) and CF-netCDF format file. CSV files can be opened as a spreadsheet. 

• What should I use them for?

• To provide a visual representation of the probabilistic climate projections.
• To help define and justify a single estimate of change.

• What to be aware of

• Exploring the climate change associated with a certain probability level.
