    113 Each ensemble section has to begin with the line `[ensemble/tag]` followed by `key = value` entries. This type of section allows to create independent realizations by overloading the key described in `DEFAULT` section, all keys expect `name` can be overloaded. Thus, ensemble sections are well-suited for sensitivity studies by modifying physical schemes, initial conditions and boundary conditions, and so on. The following experiment configuration example tries to show how to take advantage of this WRF4G feature by setting two ensemble sections in which `namelist_values` key is different :
