Plot ICON cell-centered scalar data on native triangular cells.

Parameters

dsxarray.Dataset

ICON dataset containing cell centers and triangular cell bounds.

daxarray.DataArray or numpy.ndarray

Cell-centered scalar values on ncells. Select time and vertical dimensions before calling, for example ds["temp"].isel(time=0, plev=0).

axmatplotlib.axes.Axes, optional

Axes on which to draw. By default, use the current axes.

transformcartopy.crs.CRS, optional

Coordinate reference system of the input coordinates for Cartopy axes.

lon_min, lon_max, lat_min, lat_maxfloat, optional

Plot extent in degrees. Cross-dateline longitude windows are supported.

auto_extentbool, default: True

If True and no explicit extent is supplied, infer the extent from valid cell centers.

extent_marginfloat, default: 0.05

Fractional margin added to the automatically inferred extent.

cell_marginfloat, default: 0.05

Fractional padding used when selecting triangles near the visible extent.

global_plotbool, default: False

If True, draw a global extent centered on center_lon.

center_lonfloat, optional

Longitude center used for wrapping. If None, infer it from the extent or valid cell centers.

input_radiansbool, default: True

If True, ICON longitude and latitude variables are interpreted as radians and converted to degrees.

skip_large_lon_jumpbool, default: True

If True, skip triangles with very large wrapped longitude spans.

max_polygon_lon_spanfloat, default: 180.0

Maximum accepted wrapped triangle longitude span in degrees.

cmapstr or matplotlib.colors.Colormap, optional

Colormap used for triangle values.

vmin, vmaxfloat, optional

Color limits. If omitted, infer them from selected values.

symmetricbool, default: False

If True, infer symmetric color limits around zero.

percentilefloat, default: 98

Percentile used for automatic color-limit inference.

edgecolor, linewidth

Polygon edge style passed to matplotlib.collections.PolyCollection.

add_colorbarbool, default: True

If True, add a colorbar for the polygon collection.

cbar_kwargsdict, optional

Keyword arguments passed to Figure.colorbar.

titlestr, optional

Axes title. If None, use the data long name.

xlabel, ylabelstr

Axis labels used for plain Matplotlib axes.

aspectstr or float, default: “auto”

Aspect setting used for plain Matplotlib axes.

lon_name_cell, lat_name_cell, lon_bnds_name, lat_bnds_namestr

ICON coordinate and triangular-bound variable names.

Returns

matplotlib.collections.PolyCollection

Polygon collection added to the axes.
