Climate Predictability Tool (CPT) is an easy-to-use Windows-based software package for making downscaled seasonal climate forecasts.
It runs on Windows 95+. A source code version, which has no GUI or any of the graphics capabilities, is available for other platforms.
Specifically, CPT is designed to produce statistical forecasts of seasonal climate using either the output from a GCM, or fields of sea-surface temperatures.
The program provides extensive tests indicating forecast performance.
