Grids are defined in GRIB2 using an accuracy of 1/1000000 (one millionth) of a degree. If this accuracy is not sufficient to describe your grid (latitude/longitude of first and last points, as well as grid increments) without loss of information, you can use a GRIB2 feature that provides a way to describe any regular grid.
Please fill in the numbers that match your grid. You find the GRIB 2 code figures below.
| Number of points along a parallel: | ||
| Number of points along a polar great circle: |
| Scanning mode: |  | j scans positively | |
| j points are consecutive | alternate row scanning |
