Fine-mesh grid
From Glossary of Meteorology
fine-mesh grid
A nonspecific term indicating that a grid has relatively high resolution, that is, that its grid points are relatively near to each other.
In the past, a grid length of less that 200 km was generally considered to be fine mesh, but with the rapid growth of computer power permitting the use of extremely high-resolution grids, the term is now used in a more contextual manner.
