MET Online Tutorial for METv8.0 | Additional Tools > Shift-Data-Plane

This tool may be run to perform a rigged shift of the entire grid based on user-defined specifications and write the field(s) out in NetCDF format. This tool was originally designed to account for track error when comparing fields associated with tropical cyclones. The user specifies the latitude and longitude of the source and destination points to define the shift. Both points must fall within the domain and are used to define the X and Y direction grid unit shift. The rigid is then applied to all grid points. The user may specify the method of interpolation and the field to be shifted. The effects of topography and land/water masks are ignored.

Shift-Data-Plane Usage

View the usage statement for Shift-Data-Plane by simply typing the following:

shift_data_plane

At a minimum, the following five arguments must be passed: the gridded data file (input_filename), the output NetCDF file (output_filename), the data to be shifted from the input file (field_string), the starting location to define the shift (-from lat lon), and the ending location to define the shift (-to lat lon).
