An ensemble of trend preserving statistically downscaled projections for key marine variables under three different future scenarios for the Chilean coast

Description

The ensemble provides future projections of key marine variables under climate change for the Chilean coast. The datasets were produced for three different future scenarios (SSP1-2.6, SSP2-4.5 and SSP5-8.5) and three different variables (potential temperature, dissolved oxygen, and pH) at three different depth levels (5m, 25m and seafloor with the exception of chlorophyll) at monthly frequency for the years 1993 - 2099. The statistical metrics provided are the mean, standard deviation, minimum, maximum median, 2.5 and 97.5 percentile. The ensemble is computed over 4-7 different CMIP6 model realisations (depending on variable), the bias corrections and statistical downscaling applied is based on the methodology by Lange, 2019 and was trained on the GLORYS12V1 reanalysis provided by the Copernicus Marine Environment Monitoring Service (CMEMS). The following Earth System Models were used in building the ensemble: CMCC-ESM2 (Lovato et al. 2022) CMCC-CM2-SR5 (Cherchi et al. 2019) CanESM-CanOE (Swart et al., 2019) GFDL-ESM4 (Dunne et al., 2020) MIROC-ES2L (Hajima et al., 2020) MPI-ESM1-2-LR (Mauritsen et al., 2020) UKESM1-0-LL (Sellar et al., 2019)   Analogue datasets are provided in separate zenodo entries for the regions of the Mediterranean Sea, the North Sea, the Baltic Sea, the Bay of Biscay and the area around the Yucatán Peninsula, see “Related identifiers”.   We acknowledge the World Climate Research Programme's Working Group on Coupled Modelling, which is responsible for CMIP.
