Paleo-flux Phanerozoic per basins (sediment and water)

The dataset contains netcdf outputs from global-scale landscape evolution model assimilating paleo-elevation and paleo-climate reconstructions over the past 541 Myr. The results are provided as global 0.05 degree resolution grids and include high resolution paleo-physiography maps, water and sediment fluxes, long-term erosion/deposition rates, and several morphometrics related to landscape dynamics (i.e., drainage basin ids, topographic position index, physiographic diversity).

The simulations are performed using goSPL model (Global Scalable Paleo Landscape Evolution - https://gospl.readthedocs.io) and rely on the paleo-elevation reconstructions from Scotese & Wright (2018) (PALEOMAP Project - https://doi.org/10.5281/zenodo.5460860) and precipitation grids from Valdes et al. (2021) (https://doi.org/10.5194/cp-17-1483-2021 | data available from the Bristol Research Initiative for the Dynamic Global Environment. Model ref: https://www.paleo.bristol.ac.uk/ummodel/scripts/html_bridge/scotese_02.html).

本数据集包含由同化了过去541百万年古海拔与古气候重建数据的全球尺度地貌演化模型（global-scale landscape evolution model）生成的网络通用数据格式（netCDF）输出结果。所有成果以全球0.05度分辨率网格形式提供，涵盖高分辨率古地貌图、水沙通量、长期侵蚀/沉积速率，以及多项与地貌动力学相关的地貌形态计量参数，具体包括流域ID、地形位置指数（topographic position index）与地貌多样性。

本次模拟实验采用goSPL模型（全球可扩展古地貌演化模型，全称Global Scalable Paleo Landscape Evolution——https://gospl.readthedocs.io）完成，其所依赖的数据源包括：Scotese与Wright（2018）发布的古海拔重建数据（PALEOMAP项目，链接：https://doi.org/10.5281/zenodo.5460860），以及Valdes等人（2021）提供的降水网格数据（链接：https://doi.org/10.5194/cp-17-1483-2021 | 数据可从布里斯托尔动态全球环境研究倡议获取，模型参考链接：https://www.paleo.bristol.ac.uk/ummodel/scripts/html_bridge/scotese_02.html）。
