%description
Statistical downscaling and bias correction of climate predictions. It
includes implementations of commonly used methods such as Analogs, Linear
Regression, Logistic Regression, and Bias Correction techniques, as well
as interpolation functions for regridding and point-based applications. It
facilitates the production of high-resolution and local-scale climate
information from coarse-scale predictions, which is essential for impact
analyses. The package can be applied in a wide range of sectors and
studies, including agriculture, water management, energy, heatwaves, and
other climate-sensitive applications. The package was developed within the
framework of the European Union Horizon Europe projects Impetus4Change
(101081555) and ASPECT (101081460), the Wellcome Trust supported HARMONIZE
project (224694/Z/21/Z), and the Spanish national project BOREAS
(PID2022-140673OA-I00). Implements the methods described in 'Ramon et al.
(2021) <doi:10.1088/1748-9326/abe491>', 'Duzenli et al. (2024)
