We are happy to announce that our project High-resolution climate projections was selected by the Copernicus Climate Change Service (C3S) for deployment as a use case. The project aims at producing a dataset of high-resolution CMIP5 climate projections through statistical downscaling using the latest C3S reanalysis products: ERA5 and ERA5-Land. Those reanalyses are becoming the most widely used data products to understand historical climate in adaptation studies, especially where observational data are scarce. Having CMIP5 projections on the same spatial resolution at daily scale provides a seamless view of the possible future climate.
During the first part of 2020, six essential climate land surface variables from all the CMIP5 projections available on the CDS are being downscaled globally (≈25x25km) using ERA5 and over Europe (≈9x9km) using ERA5-Land. Those six variables, the most requested by adaptation professionals, are temperature (daily, minimum, and maximum), surface precipitation, wind speed, and solar radiation. The data will be quality assured and methodological uncertainties will be quantified.
