MARS/Dissemination
Specifies a rotation of the target grid.
rotation=<value> |
|---|
A rotation is requested by specifying the position of the South Pole of the rotated grid as latitude/longitude in degrees, e.g. rotation = -30.0/10.0.
| Value | Comment |
|---|---|
rotation = off | no rotation (default) |
rotation = a/b | a is the latitude of the South Pole of rotation in deg. b is the longitude of the South Pole of rotation in deg. |
Rotation is strictly linked to the keyword GRID:
| GRID specification | target grid |
|---|---|
grid=lat/lon | rotated regular lat/lon |
grid=F... | rotated full Gaussian grid |
grid=N... | rotated reduced Gaussian grid |
grid=O... | octahedral (reduced) Gaussian grid |
and usually specified together with an AREA. Target fields in spherical harmonics are not supported. Target fields in spherical harmonics are not supported. The default interpolation method used is linear.
