The Climate Predictability Tool
- The Climate Predictability Tool (CPT) is a software package for constructing a seasonal climate forecast model, performing model validation, and producing forecasts given updated data. Its design has been tailored for producing seasonal climate forecasts using model output statistic (MOS) corrections to climate predictions from general circulation model (GCM), or for producing forecasts using fields of sea-surface temperatures or similar predictors. Although the software is specifically tailored for these applications, it can be used in more general settings to perform canonical correlation analysis (CCA), principal components regression (PCR), or multiple linear regression (MLR) on any data, and for any application.

PyCPT was created as an easy-to-use Python interface to CPT, helping automate and mass-produce CPT tasks that will normally take more time in the Windows version. The seasonal and subseasonal versions of PyCPT provide seamless access to the North American Multi-Model Ensemble (NMME) the Copernicus Climate Change Services (C3S), the Subseasonal-to-Seasonal Prediction Project (S2S) and the Subseasonal Experiment (SubX) Databases, respectively, via the IRI Data Library.
Latest News! A new version of PyCPT for seasonal forecasts (PyCPT 2.5) is now available (see links on right).
CPT is the main tool used to implement the Next Generation (#NextGen) system to produce calibrated forecasts at multiple timescales, following the World Meteorological Organization standards.
