Comparing History Files
|
|
=========================
|
|
|
|
**cprnc** is a tool shared by |cesmrelease| to compare two NetCDF history files.
|
|
It differences every field that is shared on both files, and reports a summary of the difference.
|
|
The summary includes the three largest differences, as well as the root mean square (RMS) difference.
|
|
It also gives some summary information on the field as well.
|
|
You have to enter at least one file, and up to two files.
|
|
With one file it gives you summary information on the file, and with two it gives you information on the differences between the two.
|
|
At the end it will give you a summary of the fields compared and how many fields were different and how many were identical.
