Internal wave-driven mixing and geothermal heating for NEMO

this dataset contains seven netcdf files that can be used, inter alia, to run the nucleus for european modelling of the ocean (nemo) model with a parameterization for internal wave-driven mixing and geothermal forcing at the seafloor activated.- four files (with names including ‘zdfiwm_forcing_’) contain six two-dimensional (longitude, latitude) fields that are read by the ‘zdfiwm.f90’ routine of nemo. these fields are provided on the orca2, eorca1 and orca05 global grids, as well as on a regular grid at half-degree resolution. the fields on the regular grid can be used to create higher resolution forcing fields via interpolation. note that the interpolation should not create negative values.- three files (with names including ‘geothermal_forcing_’) provide the geothermal heat flux mapped by lucazeau (2019) which is read by the ‘trabbc.f90’ routine of nemo. this file is provided on the orca2 and eorca1 global grids, as well as on a regular grid at one-degree resolution. interpolation can be used to create fields for other nemo grids. again, such interpolation should not create negative values.further description of these forcing files and the associated parameterizations, together with an analysis of their effects in long eorca1 experiments, can be found in references provided below. note that the ‘zdfiwm_forcing_…’ forcing files provided here include power from subinertial internal tides, as described in de lavergne et al. (2024).the file formats are suited to nemo version 4.2 and more recent versions. they can readily be modified to work with earlier versions of nemo.references:de lavergne, c., rathore, s., madec, g., sallée, j.-b., ethé, c., nasser, a., millet, b., and vancoppenolle, m. effects of improved tidal mixing in nemo one-degree global ocean model. ess open archive (2024). https://doi.org/10.22541/essoar.173152139.95978362/v1de lavergne, c., vic, c., madec, g., roquet, f., waterhouse, a., whalen, c.b., cuypers, y., bouruet-aubertot, p., ferron, b., and hibiya, t. a parameterization of local and remote tidal mixing. journal of advances in modeling earth systems, 12, e2020ms002065 (2020). https://doi.org/10.1029/2020ms002065lucazeau, f. analysis and mapping of an updated terrestrial heat flow data set. geochemistry, geophysics, geosystems, 20, 4001-4025 (2019). https://doi.org/10.1029/2019gc008389

本数据集包含七个 NetCDF 文件，可用于诸如运行欧洲海洋模型（NEMO）之核（Nucleus for European Modelling of the Ocean）模型等用途，其中模型参数化考虑了内部波浪驱动的混合作用以及海底地热强迫。其中，包含‘zdfiwm_forcing_’字样的四个文件包含了六个二维（经度，纬度）场，这些场由 NEMO 的‘zdfiwm.f90’子程序读取。这些场值提供于 ORCA2、EORCA1 和 ORCA05 全球网格，以及半度分辨率的规则网格上。规则网格上的场值可用于通过插值创建更高分辨率的强迫场。需要注意的是，插值过程不应产生负值。另外，包含‘geothermal_forcing_’字样的三个文件提供了卢卡泽（Lucazeau，2019）所测绘的地热热通量，该热通量由 NEMO 的‘trabbc.f90’子程序读取。此文件提供于 ORCA2 和 EORCA1 全球网格，以及一度分辨率的规则网格上。插值可用于创建其他 NEMO 网格的场值。同样，此类插值过程亦应避免产生负值。关于这些强迫文件及其相关参数化的进一步描述，以及它们在长期 EORCA1 实验中的影响分析，可参考下述参考文献。需要注意的是，此处提供的‘zdfiwm_forcing_…’强迫文件包含了描述于德·拉韦日奈等（De Lavergne et al.，2024）中的次惯性内潮能量。文件格式适用于 NEMO 4.2 及更晚版本，易于修改以适应早期版本。参考文献：De Lavergne, C., Rathore, S., Madec, G., Sallée, J.-B., Ethé, C., Nasser, A., Millet, B., 和 Vancoppenolle, M.（2024）。NEMO 一度全球海洋模型中改进潮汐混合作用的影响。ESS 开放存档。https://doi.org/10.22541/essoar.173152139.95978362/v1De Lavergne, C., Vic, C., Madec, G., Roquet, F., Waterhouse, A., Whalen, C.B., Cuypers, Y., Bouruet-Aubertot, P., Ferron, B., 和 Hibiya, T.（2020）。局部和远程潮汐混合作用的参数化。地球系统建模进展，12，e2020ms002065。https://doi.org/10.1029/2020ms002065Lucazeau, F.（2019）。更新版陆地热流数据集的分析与制图。地球化学、地球物理学、地球系统，20，4001-4025。https://doi.org/10.1029/2019gc008389
