  "term": "Gaussian grid",
  "field": "Meteorology and atmospheric science",
  "definition": "A specific type of latitude-longitude grid used in atmospheric and climate models, where the grid points in the latitudinal direction are spaced according to the roots of Legendre polynomials. This non-uniform spacing provides higher resolution near the poles while maintaining computational efficiency. It is often employed in spectral models to avoid aliasing errors during transformations between spectral and grid-point representations.",
