Abstract. Statistical downscaling methods provide an essential bridge between low resolution global climate models and localized information needed by decision makers. As the demand for localized climate information continues to grow to make projections for a wide variety of applications, the need for software that can provide this sort of downscaled data grows with it. The CCdownscaling package described in the article provides a number of downscaling methods, including Self Organizing Maps, as well as a number of evaluation metrics for assessing downscale model skill. In this article, we describe the features of the CCdownscaling package, and show an example use case for downscaling temperature and precipitation. It is open-source and freely available for use in generating downscaled projections.

Short summary
Statistical downscaling provides methods to bridge the gap between the global climate models and the scale of information needed to understand the impacts of climate change. This paper describes a new software package that provides a number of statistical downscaling approaches, as well as evaluation metrics for these methods. The goal of this work is to provide a new tool for researchers carrying out downscaling studies, and enable the easy use and comparison of different downscaling methods.
