This set of explanatory notes provided the process of creating the 2019 National Gravity Grids released September 2020. This information provides a step by step guide to the processing sequence undertaken. The Notes provide: 1) the data sources for the grids, such as Geoscience Australia's National Airborne Geophysics Database (NAGD), the Australian National Gravity Database (ANGD), and Sandwell and Smith (v28p1) satellite gravity data. 2) Equations used to reduce gravity, gridding calculations, and observation surface for the "B" series grids, 3) Step by step processing sequence. There is also a section with a simple aid to interpreting the grids. The grids are available either as a complete set of grids, or individually, from the associated link.
