Here are examples of generating Lambert grids.

regrid_lambert_conformal = mv.regrid(
    grid_definition_mode = "lambert_conformal",
    first_point          = [50.88,-1.66],
    dx_in_metres         = 2500,
    dy_in_metres         = 2500,
    nx                   = 739,
    ny                   = 949,
    lad_in_degrees       = 63,
    lov_in_degrees       = 15,
    data                 = t_2m_rgg
    )

regrid_lambert_azimuthal = mv.regrid(
    grid_definition_mode         = "lambert_azimuthal_equal_area",
    first_point                  = [50.88,-1.66],
    dx_in_metres                 = 2500,
    dy_in_metres                 = 2500,
    nx                           = 739,
    ny                           = 949,
    standard_parallel_in_degrees = 0,
    central_longitude_in_degrees = 0,
    data                         = t_2m_rgg
    )

Grid Definition Mode: Filter

...

For example, this set of parameters generates the following output data:

t01 = mv.regrid(
    grid     = [0.1,0.1],
    area     = [31,-17,64,38],
    data     = t_2m
    )

mv.plot(t01)

Frame

Specifies the width of a frame within a given sub-area, as described here frame - keyword in MARS/Dissemination request.

The width of the frame is specified as an (integer) number of grid points inwards from a given area. The following plots show a sub-area with Frame=10.

Rotation

Position of the South Pole of the intended rotated grid as lat/lon in degree, as described here: rotation - keyword in MARS/Dissemination request.

...

Activates a nabla (differential) operator processing on the fields. Possible functions are:

• Scalar Gradient: QQQ
• Scalar Laplacian: QQQ
• UV Divergence: QQQ
• UV Gradient: QQQ
• UV Vorticity: QQQ
• Off: do not perform any nabla operation

Nabla Poles Missing Values

QQQ. Possible values are On and Off.

...

• Distance Weighting Shepard Power: specify Shepard's method power parameter (see Wikipedia specific section)
• Distance Weighting Gaussian Stddev: specify Gaussian standard deviation (see Wikipedia)

Non Linear

QQQ. Possible values are:

• Missing If All Missing: QQQ
• Missing If Any Missing: QQQ
• Missing If Heaviest Missing: QQQ
• Simulated Missing Value: QQQ
• Heaviest: QQQ
• No: QQQ

Simulated Missing Value

Only available if Non Linear is Simulated Missing Value. QQQ (description)

Simulated Missing Value Epsilon

Only available if Non Linear is Simulated Missing Value. QQQ (description)

Land-sea mask parameters

Distance Weighting With LSM

...

Only available if Distance Weighting With Lsm is not Off. QQQ.

LSM

LSM Selection Input/Output

...

If input/output is not the same geometry (grid) as provided input/output LSM (respectivellyrespectively), interpolate with this method to a temporary LSM with required geometry.
