The loaded dataset has add-on attributes such as comp and grid that are useful for later analysis and visualization. The add-on attribute path is good for file tracking.
Note that the time axis is offset by one month in the raw iCESM1 output, and x4c.load_dataset() provides the option adjust_month=True to fix this issue. This won’t be an issue for CESM2 & 3 outputs.
