Code and ROMS configurations for “Scale-dependent Constraints on the Recoverability of Sea Surface Height from Mesoscale Information”

<p dir="ltr">This repository contains code and ROMS configuration scripts accompanying the manuscript “Scale-dependent Constraints on the Recoverability of Sea Surface Height from Mesoscale Information.”</p><p dir="ltr">The study investigates the recoverability of finer-scale sea surface height (SSH) variability from mesoscale information in the Kuroshio Extension using a conditional generative diffusion model. Scale-filtered SSH inputs are constructed with cutoff wavelengths ranging from 50 to 250 km.</p><p dir="ltr">The repository includes:</p><p dir="ltr">• <b>DM:</b> Neural-network implementation and training scripts for the nine cutoff-scale experiments.<br>• <b>ROMS8KM and ROMS20KM:</b> Configuration and run scripts for the approximately 8-km and 20-km ROMS simulations used to evaluate the filtering methods.<br>• <b>PLOT:</b> MATLAB scripts for data preprocessing, spatial filtering, diagnostic analysis, and figure generation.</p><p dir="ltr">The GLORYS12V1 source data are available separately through the Copernicus Marine Service, product GLOBAL_MULTIYEAR_PHY_001_030.
