-The **regrid** dictionary is common to multiple MET tools and is described in :numref:`config_options`. It specifies how the input data should be regridded to cylindrical coordinates prior to compute diagnostics. It can be specified separately in each **data.field** array entry, described below. The default setting uses nearest neighbor interpolation for all fields.
