Data Selection

You can interactively pick out the data you would like with the Data Viewer.

You can reduce the amount of data by restricting the range of the grids.

The current settings for the grids are
  • grid: /lon (degree_east) periodic (0) to (0.25W) by 0.25 N= 1440 pts :grid
  • grid: /lat (degree_north) ordered (89.875S) to (89.875N) by 0.25 N= 720 pts :grid
  • grid: /zlev (meters) ordered [ (0.0)] :grid
  • grid: /T (days since 1978-01-01 12:00:00) ordered (1200 20 Sep 1981 - 1200 21 Sep 1981) to (1200 4 Oct 2019 - 1200 5 Oct 2019) by 1.0 N= 13894 pts :grid
If this is what you want, choose Stop Selecting: on to the smaller dataset

Hints

More General Data Selection

Otherwise, you select data by picking a grid and specifying which values of that grid you want. You can specify a RANGE, or single or multiple VALUES.

If you want all of the data along a particular grid, you do not need to do any selecting: only select a grid that you want to reduce the amount of data along.

P.S.: the Data Viewer lets one select data with a graphical interface. It works even for datasets with three or more dimensions.
