Gravimetric Mass Balance refers to the changes in the mass of ice sheets determined from satellite gravimetry, which measures variations in the Earth's gravity field due to ice mass changes. These data are crucial for understanding how ice sheets contribute to sea level rise.\n", "\n", "The GMB data provides estimates of ice mass loss or gain over time, derived from satellite-based gravimetric measurements from the GRACE and GRACE-FO satellites. These measurements track changes in the gravitational field caused by shifts in mass, such as the movement or melting of ice. The GMB data allows researchers to monitor long-term trends in ice sheet dynamics and their contribution to global sea level changes.\n", "\n", "It will show you how to download data from the C3S Climate Data Store (CDS), calculate average change rates over a selectable period, and display the results." ] }, { "cell_type": "markdown", "id": "c78b3f54", "metadata": {}, "source": [ "### Data Description:\n", "\n", "- **Source**: Copernicus Climate Change Service (C3S) Climate Data Store (CDS) \n", "- **Data Type**: Satellite-based gravimetric measurements\n", "- **Coverage**: Greenland and Antarctic ice sheets\n", "- **Variables**: Time series of mass balance changes over specific regions with basin numbers\n", "- **Format**: NetCDF4 files" ] }, { "cell_type": "markdown", "id": "aa1d689d", "metadata": {}, "source": [ "## Prerequisites and data acquisition\n", "\n", "This tutorial is in the form of a Jupyter notebook.
