Getting Started

After starting the software, the Introductory Window will be opened, indicating the title of the software, and showing the IRI banner. The Window title (the very top row of the Window), should indicate the version of the software being used. Further details of the software version are available in the menu bar immediately below the title bar, as described below. There should be four menu items:

From the Introductory Window, the File menu item offers only the option to Open a pre-existing Project File, or to Exit the software. The Options ~ Language allows the user to set the language of the interface and graphics text. If the language is changed, the new language will be used as the default the next time CPT is started. Help ~ About gives details about the version of the software, and Help ~ Home provides more general help (these pages). These help pages are available from anywhere within the program.

The most important menu item from the Introductory Window is View. This item offers a choice of analysis methods:

  • Canonical Correlation Analysis (CCA)
  • Principal Components Regression (PCR)
  • Multiple Linear Regression (MLR)
  • Raw GCM Model Output (GCM)
  • Probabilistic Forecast Verification (PFV)

Any of the first four methods can be used to construct a model for seasonal climate forecasting, while the PFV option can be used to verify independent or previously geenerated probabilistic forecasts. Once you have selected an analysis method you will be prompted for the various settings and input files to construct the forecasting model.
