Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Global
Model domain	Terrestrial, Geodynamic, Climate
One-line model description	Global Scalable Paleo Landscape Evolution
Extended model description	gospl is able to simulate global-scale forward models of landscape evolution, dual-lithology (coarse and fine) sediment routing and stratigraphic history forced with deforming plate tectonics, paleotopographies and paleoclimate reconstructions. It relates the complexity of the triggers and responses of sedimentary processes from the complete sediment routing perspective accounting for different scenarii of plate motion, tectonic uplift/subsidence, climate, geodynamic and sedimentary conditions.

Describe input parameters	paleo-landscape, paleo-climate, plate reconstruction
Input format	ASCII, Binary
Other input format
Describe output parameters	evolving landscape, stratigraphy
Output format	Binary
Other output format
Pre-processing software needed?	Yes
Describe pre-processing software	Available as jupyter notebooks based on CSV and numpy compressed arrays format. The documentation contains some workflows and functions that helps, among others, to pre-process netCDF elevation and climate dataset, plate velocity files and to create an unstructured spherical mesh used as input for gospl.
Post-processing software needed?	Yes
Describe post-processing software	Python workflows. Outputs are generated as compressed hdf5 files (The HDF Group, 2000-2010) that can be simply visualise as a temporal series in ParaView (Ahrens et al., 2005). In addition, post-processing scripts are also provided to build the output as VTK (Schroeder et al., 2006) or netCDF files (Brown et al., 1993) and to extract some specific information from the results such as erosion deposition thicknesses, stratigraphic records or river sediment load over time.
Visualization software needed?	Yes
If above answer is yes
Other visualization software	Paraview

Describe processes represented by the model	global-scale forward models of landscape evolution, dual-lithology (coarse and fine) sediment routing and stratigraphic history forced with deforming plate tectonics, paleotopographies and paleoclimate reconstructions.
Describe key physical parameters and equations	• river incision using the stream power law (Howard et al., 1994) based on a multiple flow direction approach and an implicit parallel implicit drainage area method (Richardson et al., 2014), • inland river deposition in depressions computed using priority-flood techniques (Barnes et al., 2014), • dual-lithology marine deposition at river mouth based on a diffusion algorithm (Rivenaes, 1992), • hillslope processes in both marine and inland areas (Salles, 2019), and • sediment compaction as stratigraphic layers geometry and properties changes (Sclater & Christie, 1980; Yuan et al., 2019).
Describe length scale and resolution constraints	global scale (5 to 100 km). gospl can be used with different mesh resolutions enabling better representation of surface processes in regions of interest (e.g., specific basins, continental regions) while using lower resolutions to save memory allocation in other parts (deep marine regions for example).
Describe time scale and resolution constraints	long term (several millions of years) problems.
Describe any numerical limitations and issues	Documentation provides a description of the available processes and associated limitations: https://gospl.readthedocs.io/en/latest/tech_guide/index.html

Describe available calibration data sets	The user guide covers essential features of gospl, mostly in the form of interactive Jupyter notebooks and Python scripts. https://gospl.readthedocs.io/en/latest/user_guide/index.html
Upload calibration data sets if available:
Describe available test data sets	+ data structure used in gospl input file, + how to generate initial conditions like topography, precipitation and tectonic maps to force a simulation, + how to extract some of the output from the model results to visualise them in Jupyter notebooks, + how to run sequence of backward/forward gospl models using Python functions, + how to set a script for running gospl on HPC.
Upload test data sets if available:
Describe ideal data for testing	It can be used to test different hypothesis related to Earth past evolution and to characterise the role of several drivers such as precipitation, dynamic topography, sea-level on Earth landscape evolution and sedimentary basins formation.
