MEDSCOPE is developing and distributing a toolbox, CSTools, designed and built to improve the quality of climate forecasts in the Mediterranean region on seasonal to multi-annual scales, along with a number of examples of sectoral applications of relevance for the region. The improved climate prediction information will be achieved both via a better understanding of the Mediterranean climate variability and predictability and on the development of innovative methodologies to extract the information from climate predictions.

THE MEDSCOPE TOOLBOX, CSTools, also includes results of user engagement meetings, instructions for users, examples of sectoral applications, and much additional content.

CSTools is an R package and a preliminary version is publicly available on the CRAN repository. This tool, thought to assess the skill of Climate forecasts on seasonal-to-decadal timescales, exploits dynamical seasonal forecasts in order to provide information relevant to stakeholders at the seasonal timescale. The package contains process-based methods for forecast calibration, bias correction, statistical and stochastic downscaling, optimal forecast combination and multivariate verification, as well as basic and advanced tools to obtain tailored products (Table 1).


Table 1: Summary of the currently included functions.



The package includes the description of each individual function through the typical R channels, including the pdf document and an overview of the package is also available in a poster format here.

While other guidelines on how to use the software are provided in the shape of vignettes* showing how to analyze climate data:

* an instructive tutorial demonstrating practical uses of the software with the discussion of the interpretation of the results.


You can install the publicly released version of CSTools from CRAN in your R session:

> install.packages(“CSTools”)

and start using it by loading it:

> library(CSTools)
