meteoblue NMM (numerical mesoscale models) divide the space into grid cells. These cells represent the area surrounding them.
The distance between the grid cells determines the spatial resolution which is equivalent to twice the radius of each grid cell. Each cell is defined by a center point, with coordinates and an altitude. The altitude is the calculated average of all surface points within the grid cell (radius), based on a 100 meter topography model. Other grid cell attributes include surface type, land cover and inclination.
