The four possible grids for the MODLAND fine resoultion L3 products are
based on the map projections:
Almost all of the fine resolution L3 land products are
made in the Sinusoidal Grid. The L3 fine resolution
Sea-ice products are the only exception and
are made in the in the Lambert Azimuthal Equal-Area projection with the grid
centered at the north and south poles.
For Collection 3 and before the Sinusoidal Grid products were made in the
Integerized Sinusoidal Grid.
The grid cell size varies by product and is either (approximately) 0.25 km, 0.5 km
or 1 km. The actual size depends on the projection.
- Integerized Sinusoidal
- Goode's Homolosine
- Lambert Azimuthal Equal-Area (polar grids)
- Hammer Atioff
Each grid is broken into a number of non-overlapping tiles which cover
approximately 10x10 degree area. The tiles are labeled with a
vertical and horizontal tile id.
In additional, the MODLAND coarse resolution global Climate Modeling Grid (CMG)
products will be made in a
geographic projection. The grid cell sizes for these products are
