Data sources

The following sources were used to produce files in this dataset:

• The Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales (HydroSHEDS), obtained from HydroSHEDS website http://hydrosheds.org/
• The Global Land Data Assimilation System (GLDAS), obtained from https://ldas.gsfc.nasa.gov/gldas/.  Model outputs used are GLDAS_MOS10_M.001, GLDAS_NOAH010_M.001, and GLDAS_VIC10_M.001

Description of files

The files in this dataset contain are described below:

• SGD data file.xlsx.  The .xlsx file contains the following data (units are in parentheses):
  • ObjectID. Unique feature identifier in HydroSHEDS.
  • Coastal Catchment Area (km^2)
  • Coastline Length (km)
  • Longitude. Longitude of the point represents the centroid of the catchment.
  • Latitude. Latitude of the point represents the centroid of the catchment.
  • Drainage Length (km). The average distance of the coastal catchment to the coastline.
  • SGD_m2/day. Average annual fresh SGD rate for catchment (m²/day).
  • SGD_m3/day. Volumetric annual fresh SGD rate for catchment (m³/day).
• SGD shapefile.zip  This file contains shapefile for the near globe SGD.
