Opening data files (and how to use Variables Pane)

1. Opening data files.

Mirae WAVE opens GRIB/GRIB2/NETCDF files saved in the local computer, extracts data variables saved in the file, and let user to visualize the data for the selected variables.

To open a file or a group of files:

  1. click Open File menu button on Home menu category, and
  2. select a single file on the Open dialog box, and click Open button.
  3. You can also open multiple files at the same time as a group, by selecting files while pressing SHIFT key.

To open all the data files in a directory:

  1. click Open Directory menu button on Home menu category, and
  2. select a folder on the Browse for Folder dialog box, and click OK button.

When Mirae WAVE successfully opens the selected file(s) or the folder, it extracts all the information about the data variables saved in the file(s), and shows the data variables on the Variables Pane, so that the user can check all the available information.

2. Using Variables Pane to manage variables.

The Variables Pane consists of two components: control bar and display area. After opening data files, the Variables Pane displays a hierarchical tree structure (File Name -> Category Name or Vertical Coordinate System -> Variable Name) of the variables in your data.
