! subprogram: setupspd compute rhs of oi for wind speed obs
! prgmmr: parrish org: np22 date: 1990-10-06
!
! abstract: For wind speed observations, this routine
! a) reads obs assigned to given mpi task (geographic region),
! b) simulates obs from guess,
! c) apply some quality control to obs,
! d) load weight and innovation arrays used in minimization
! e) collects statistics for runtime diagnostic output
! f) writes additional diagnostic information to output file
