I4C D3.4 DESCRIPTION OF THE DATA REFERENCE SYNTAX FOR ARCHIVING RESULTS OF STATISTICAL AND EMULATION-BASED DOWNSCALING

This document provides a reference syntax to describe statistically downscaled and emulated output, building on the CORDEX-CMIP6 standard. It contains a novel and detailed description of file name and attribute syntax for files containing climatological fields obtained from emulators of high-resolution dynamical model output. Such emulators are trained within the model world of a high-resolution RCM/CPM nested into a GCM. Once the optimal emulator parameters are extracted, the fitted emulator can subsequently be used to produce local data directly from GCM output. Such approach will allow to produce high resolution decadal projection ensembles in I4C. Although RCM-emulators have been around for some years, this is the first attempt to have a reference syntax for the output they produce.
