Online dynamical downscaling of temperature and precipitation within the iLOVECLIM model (version 1.1)
International audience This paper presents the inclusion of an online dy-namical downscaling of temperature and precipitation within the model of intermediate complexity iLOVECLIM v1.1. We describe the following methodology to generate temperature and precipitation fields on a 40 km × 40 km Cartesia...
