Downscaled and bias-corrected bioclimatic dataset for the Mediterranean Sea (2005–2099)

Abstract

This dataset provides annual statistical descriptors (mean, minimum, maximum, range and standard deviation) of key biogeochemical and physical variables for the Mediterranean Sea. It covers the period 2005–2099 under a high emissions scenario (CMIP5-RCP8.5), with a spatial resolution of 1/24 degree (∼4 km²). The CMIP5-RCP8.5 scenario considers the current trajectory of increasing greenhouse gas emissions and population growth to the end of the century with nominal policies to reduce emissions. Variables include temperature, salinity, pH, water velocity, nutrients (NO3, PO4, NH4), dissolved inorganic carbon, oxygen, and net primary production. Data are available for both surface and at bathymetry level. The original projections were generated using OGSTM-BFM and MFS16 models at daily time and 1/16 degree grid resolution. These were downscaled to 1/24 degree resolution and bias corrected by quantile delta mapping using CMEMS reanalysis products from 2005 to 2020. The dataset is provided in a user-friendly format so that it is accessible for various ecological and environmental modelling applications.
