Abstract:
Initialization, grid, and forcing files for running numerical simulations of offline passive tracer within the Regional Ocean Modeling System (ROMS). The simulations are presented and analyzed in the associated paper by Thyng et al., 2021. The latest version of the model code is available at Github, while the exact model version used in the published work is available at Zenodo (doi: 10.5281/zenodo.4455760 for the offline simulation and 10.5281/zenodo.4455715 for the online simulation). The output files used in the analysis are available in the related dataset under GRIIDC Unique Dataset Identifier (UDI) R6.x803.000:0020 (doi: 10.7266/7R0N3FX4). This dataset supports the publication: Thyng, K. M., Kobashi, D., Ruiz-Xomchuk, V., Qu, L., Chen, X., & Hetland, R. D. (2021).
