NetCDF xarray map plotting (version 2022.3.0+galaxy0)

Input netcdf file:

Tabular of variables:

Select the tabular file which summarize the available variables and dimensions.

Choose the variable to plot:

Name of latitude coordinate:

Name of longitude coordinate:

Datetime selection:

Use this option when your dataset contains multiple times/dates

longitudes values 'lonW,lonE' for limited geographical area (optional and only available with some projections):

latitudes values 'latS,latN' for limited geographical area (optional and only available with some projections):

Shift longitudes [0,360] --> [-180,180]:

Range of values for plotting e.g. minimum value and maximum value (minval,maxval) (optional):

Do not plot values below this threshold (optional):

Add country borders with alpha value [0-1] (optional):

Add coastline with alpha value [0-1] (optional):

Add ocean with alpha value [0-1] (optional):

Add land with alpha value [0-1] (optional):

Specify plot title (optional):

Set a label for colormap (optional):

Specify which colormap to use for plotting (optional):

Specify the projection (proj4) on which we draw e.g. {"proj":"PlateCarree"} with double quote (optional):

What it does

This tool plots a variable on a geographical map. It must be a 2D variable (latitude, longitude) and eventually with and additional time dimension (specific time to plot should then be selected).

The appearance of plots can be customized with options as well at the projection. The projection needs to be given as a PROJ dictionary such as: - {"proj":"EquidistantConic", "central_longitude": 20.0, "central_latitude": 70.0 } - {"proj":"AlbersEqualArea", "central_longitude": 20.0, "central_latitude": 70.0 } - {"proj":"EuroPP"}

The output is a collection of plots (png format); one per selected times.

The xarray select tool can be used after the xarray Info and xarray coord.
