Describe the bug
Bug reported by WRF-DART user during implementation of Poterjoy particle filter (LPF) algorithm. See assim_tools_mod_pf.f90
_I just noticed that pf_enkf_hybrid is set to 'true' by default in assim_tools_mod. Because you did not specify this option in your namelist, you are actually running a combination of an LPF-EnKF update, as described in this paper. I admit that this is an unfortunate default option (that should be changed in the DART repository) since it makes no sense for users to have to specify pf_enkf_hybrid in order to shut this feature off. In the meantime, set pf_enkf_hybrid = .false. under &assim_toolsnml in the namelist.
