Meso-scale future climate modeling (5 km resolution): application over French wine regions under the SRES A2 scenario (2041-2050)

In order to assess climate change at regional scales suitable to viticulture, the outputs of ARPEGE_Climat global model (resolution 0.5°) were downscaled using the Regional Atmospheric Modeling System (RAMS) and nested grids, providing downscaled datasets of 5 km resolution over France. Simulations were performed for two periods: 1991-2000, to assess the method against observations and […]
