The processed data for "ENSO simulation in the coupled Korean Integrated Model" submitted to GMD using Korea Integrated Model (KIM)
Year: 2026
Type: dataset
Abstract: This archive contains the model output, initial conditions, reference datasets, and analysis scripts required to reproduce the figures presented in the manuscript "ENSO simulation in the coupled Korean Integrated Model" submitted to Geoscientific Model Development. It is provided in compliance with the GMD Code and Data Policy. The data were produced with the Korea Integrated Model (KIM) coupled atmosphere–ocean system, version 25.01, at a horizontal resolution of 0.5° for the atmosphere and 0.25° for the ocean. The simulation was integrated over the period 1850–2020, and the analysis presented in the manuscript is based on the subset spanning 1952–1990. The initial conditions used to launch the coupled integration are included here, comprising the atmospheric state on the KIM cubed-sphere grid and the ocean and sea-ice states on the eORCA025 tripolar grid, all valid at 1 January 1979. The observational and reanalysis datasets used to evaluate the simulation are also included, subset to the variables, regions, and periods required to reproduce the published figures. The original sources are cited in the manuscript, and their redistribution here follows the licence terms of each provider. The analysis scripts that process these data and generate the published figures are provided in the same record, and each is named after the figure it produces.
