    • The measurement of depth of water in oceans, seas, or lakes - GEBCO bathymetry gridded data for North Sea / Baltic Sea - Derived Data

    Metadata Updated: April 26, 2022

    Overview

    This dataset contains global bathymetry, or water depth, measurements from the General Bathymetric Chart of the Oceans (GEBCO), converted into the format needed for WRF's Pre-processing System (WPS). The data are read in for the use of a depth-dependent water surface roughness scheme.

    Data Quality

    The provided 30 arc second GEBCO bathymetry data were masked with WRF's 30-second land mask data and over-water measurements (negative in GEBCO) were converted to depth (positive number relative to water surface). The data were then compared to existing lake depth values in WRF where only minor differences were found.

    Uncertainty

    The land mask data and bathymetry data are not from the same source but were collected in a similar fashion. Areas may exist where GEBCO is providing over-water information while WRF's land mask shows it is land, and vice-versa. These situations are accounted for by setting the depth to a default value where ever inconsistencies are found.

    Constraints

    This data are currently set up for ease of use with WRF and proper care should be taken when trying to use the data for other purposes. It is recommended that the GEBCO data be downloaded directly in this case.
