OceanParcels/parcels: Parcels v1.1.1: a Lagrangian Ocean Analysis tool for the petascale age

<p>Parcels v1.1.1 builds on the previous v1.1.0 release. Major changes since then:</p> <ul> <li><p>In <code>Fieldset.from_netcdf()</code>, the format of <code>filenames</code> argument has been enriched (#463). As before, <code>filenames</code> can be:</p> <ul> <li>list of files</li> <li>dictionaries of list of files, where the dictionary keys are field names</li> </ul> <p>On top of that, <code>filenames</code> can now be:</p> <ul> <li>dictionaries of lists of files, where the dictionary keys are dimension names: <code>filenames[dimension_name] = [files]</code></li> <li>dictionaries of dictionaries of lists of files: <code>filenames[field_name][dimension_name] = [files]</code></li> </ul> <p>This particularly affects the function <code>Fieldset.from_nemo()</code>:</p> <p>New <code>filenames</code> looks like:</p> <pre><code>filenames = {'U': {'lon': data_path + 'mesh_mask.nc4', 'lat': data_path + 'mesh_mask.nc4', 'data': data_path + 'U_purely_zonal-ORCA025_grid_U.nc4'}, 'V': {'lon': data_path + 'mesh_mask.nc4', 'lat': data_path + 'mesh_mask.nc4', 'data': data_path + 'V_purely_zonal-ORCA025_grid_V.nc4'}} </code></pre> <p>instead of:</p> <pre><code>filenames = {'U': data_path + 'U_purely_zonal-ORCA025_grid_U.nc4', 'V': data_path + 'V_purely_zonal-ORCA025_grid_V.nc4', 'mesh_mask': data_path + 'mesh_mask.nc4'} </code></pre> <p>This modification enables to easily read 3d curvilinear NEMO fields, when the depth dimension is in the data-files.</p> </li> <li><p>A new <code>TimeConverter</code> class converts between dates and the number of seconds that Parcels uses under the hood. This enables to read netcdf files with less common time formats, such as NOLEAP. (#456)</p> </li> <li>New <code>netcdf_engine</code> as argument for <code>Fieldset.from_netcdf()</code>, enables to open netcdf files with a different engine when the default netcdf4 engine does not work. (#460)</li> <li>Improved error messages for C-kernel generator (#457)</li> <li>Minor bug fixes</li> </ul> <p>Note that it is now recommended to use a recent version of xarray (>=0.10.8) together with Parcels, since it better parses some netcdf files used by common OGCMs.</p&gt
