Gridsets and grids

parcels.gridset module

class parcels.gridset.GridSet

Bases: object

GridSet class that holds the Grids on which the Fields are defined.

Attributes:

size

Methods

dimrange(dim)

Returns maximum value of a dimension (lon, lat, depth or time) on 'left' side and minimum value on 'right' side for all grids in a gridset.

add_grid

dimrange(dim)

Returns maximum value of a dimension (lon, lat, depth or time) on ‘left’ side and minimum value on ‘right’ side for all grids in a gridset. Useful for finding e.g. longitude range that overlaps on all grids in a gridset.

parcels.grid module

class parcels.grid.CGrid

Bases: Structure

Attributes:

grid

gtype

class parcels.grid.CurvilinearSGrid(lon: ndarray[tuple[Any, ...], dtype[_ScalarT]], lat: ndarray[tuple[Any, ...], dtype[_ScalarT]], depth: ndarray[tuple[Any, ...], dtype[_ScalarT]], time: ndarray[tuple[Any, ...], dtype[_ScalarT]] | None = None, time_origin: TimeConverter | None = None, mesh: Literal['spherical', 'flat'] = 'flat')

Bases: CurvilinearGrid

Curvilinear S Grid.

Parameters:

• lon – 2D array containing the longitude coordinates of the grid

• lat – 2D array containing the latitude coordinates of the grid

• depth – 4D (time-evolving) or 3D (time-independent) array containing the vertical coordinates of the grid, which are s-coordinates. s-coordinates can be terrain-following (sigma) or iso-density (rho) layers, or any generalised vertical discretisation. The depth of each node depends then on the horizontal position (lon, lat), the number of the layer and the time is depth is a 4D array. depth array is either a 4D array[xdim][ydim][zdim][tdim] or a 3D array[xdim][ydim[zdim].

• time – Vector containing the time coordinates of the grid

• time_origin (parcels.tools.converters.TimeConverter) – Time origin of the time axis

• mesh (str) –

  String indicating the type of mesh coordinates and units used during velocity interpolation:

  1. spherical (default): Lat and lon in degree, with a correction for zonal velocity U near the poles.

  2. flat: No conversion, lat/lon are assumed to be in m.
