Using the ExtData component: Difference between revisions

Line 93:

There are several special options and cases that the user should be aware of.

==== Constant Files ====

Occasionally the user might want to satisfy a variable with a data set that is constant (only one time on a file that has no tokens) and should not be time interpolated. If the user specifies "-" for the refresh template (update once) and ExtData finds that the file template has not tokens, and that the file itself only has one time, ExtData will note this and update the variable once, and update the variable once with this set of data.

Occasionally the user might want to satisfy a variable with a data set that is constant (not in the sense that you want to set the import to the same value but you have some geospatial data with only one time on a file that has no tokens) and should not be time interpolated. If the user specifies "-" for the refresh template (update once) and ExtData finds that the file template has not tokens, and that the file itself only has one time, ExtData will note this and update the variable once, and update the variable once with this set of data.

==== Vector Variables ====

When importing winds into an application the user has the option to handle these specially so that the u and v components are not separately treated as scalars, but as proper vector quantities when regridding to the target grid. Currently this is only supported when going from Lat-Lon data to an application on the Cube-Sphere grid. The syntax is for this is as follows:
