Tutorials

The examples in this tutorials are builds using Jupyter notebooks, which can be downloaded from the github repository.

• Visualize spherical harmonic filters in the spatial domain
  • 1. Import the necessary modules
  • 2. Define a set of locations and create unit loads at the specified locations
  • 3. Filter the unit loads with a Gaussian filter
  • 4. Add a version which is filtered with an anisotropic DDK4 filter
  • 5. Apply spherical harmonic synthesis on grids centered on the locations
  • 6. Visualize the filter kernels
  • 7. Interpretation
• Compute Terrestrial Water Storage anomalies from GRACE-FO data
  • 1. Load the necessary python modules
  • 2. Load the sample data from the tarball (making use of the tables in the sqlite file)
  • 3. Create anomalies by subtracting the static gravity field from the monthly solutions
  • 4. Convert to Terrestrial Water Storage
  • 5. Grid to a global grid and make a quick visualization of a certain month
  • 6. Filtering of GRACE
  • 7. Visualize Time Series
  • 8. Interpretation
