      <description descriptionType="Abstract">The dataset provides a set of 8 land ocean masks as NetCDF files based on the maps provided by the datasets ESA CCI Water Bodies - v4.0, Ocean-Map-150m-P13Y-2000-v4.0. The masks come as regular lon/lat grids in 0.1°, 0.25°, 0.5° and 1° spatial resolution, each as a version with and without Greenland and the antarctic regions (anything south of 60° S).    <br/>
         <br/>
The data fields of the individual datasets comprise of    <br/>
a) a field with information on the fraction of land in a grid cell, defined by the number of 150m cells of the source dataset lying within a target grid cell,    <br/>
b) a field with a flag (1 or 0) if a a grid cell contains more than 50% land area or not, and    <br/>
c) a field with a flag (1 or 0) if a grid cell contains any land at all.    <br/>
         <br/>
The dataset was generated in the course of the project "Global Gravity-based Groundwater Product (G3P)" to facilitate data production on a regular grid and to mask out oceans. G3P was funded by the EU Horizon 2020 programme in response to the call LC-SPACE-04-EO-2019-2020 “Copernicus evolution – Research activities in support of cross-cutting applications between Copernicus services” under grant agreement No. 870353.   <br/>
