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: /X (degree_east) periodic (0) to (1W) by 1.0 N= 360 pts :grid
  • grid: /Y (degree_north) ordered (90S) to (90N) by 1.0 N= 181 pts :grid
  • grid: /L (days) ordered (0.5 days) to (44.5 days) by 1.0 N= 45 pts :grid
  • grid: /M (ids) ordered (0) to (9) by 1.0 N= 10 pts :grid
  • grid: /S (days since 1960-01-01) ordered (0000 6 Jan 1999) to (0000 30 Dec 2015) by 7.0 N= 887 pts :grid
  • grid: /P (hPa) ordered (850 hPa) to (200 hPa) N= 2 pts :grid
If this is what you want, choose Stop Selecting: on to the smaller dataset

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.
