pyslfp: Standardized Geographic and Physical Datasets for Sea Level Fingerprinting

This repository contains the standardized physical and geographic datasets required for the pyslfp Python library—a tool for computing self-consistent sea-level fingerprints and solving the sea-level equation on an elastic, rotating Earth.

Glacial Isostatic Adjustment (GIA) Ice History Models
Includes global ice thickness, topography, and sea-level time-slices for the ICE-5G, ICE-6G (VM5a), and ICE-7G (VM7) models.

Elastic Load Love Numbers
Elastic Load Love numbers and tidal Love numbers calculated for the Preliminary Reference Earth Model (PREM; Dziewonski & Anderson, 1981).
Methodology: These values were calculated using a spectral method implementation based on the method within: Al-Attar, D., & Tromp, J. (2014). "Sensitivity kernels for viscoelastic loading based on adjoint methods." Geophysical Journal International, 196(1), 34–77.

Regional Geographic Datasets
Standardized shapefiles used for spatial masking and regional projections:

Antarctic Basins: IMBIE2 drainage basins (Rignot et al., 2011).

Greenland Basins: Mouginot drainage basins (Mouginot et al., 2019).

Hydrological Basins: HydroBASINS Level 3 combined global river basins (Lehner & Grill, 2013).

Oceanic Regions: IHO World Seas v3 (Marine Regions).

Gloss Network locations: PSMSL (Permanent Service for Mean Sea Level). Tide Gauge Data. Holgate, S. J., et al. (2013). 

ETOPO: NOAA National Centers for Environmental Information. 2022: ETOPO 2022 15 Arc-Second Global Relief Model. NOAA National Centers for Environmental Information. DOI: 10.25921/fd45-gt74. 

Usage:
These datasets are designed to be managed by the pyslfp.downloader module. The library automatically fetches these files and stores them in a local data directory (typically ~/.pyslfp_data).
