Topography Dataset

Introduction

The Topography dataset (TOPO) is a fixed data product providing a land-water mask together with topographic height information over land. The format is netCDF4.0. The product reports land fraction in percent, shore distance in km, the mean and standard deviation of topographic height in meters (only land points included in the statistics in mixed land-water grid cells). Shore distance is the distance to the center of the nearest land-dominated (land fraction >65%) or mixed land-water (coast) grid cell if the map grid cell is water-dominated (land fraction < 35%) or to the nearest water-dominated or coast grid cell if the map grid cell is land-dominated. The distance is 0 km for coast map grid cells. Versions are available in equal-area map grids, equivalent at the equator to latitude-longitude intervals of 0.1, 0.25, 0.50, 1.0, 2.0 and 2.5 degrees.
