! subprogram: setupwspd10m compute rhs for conventional 10 m wind speed
! prgmmr: pondeca org: np23 date: 2014-03-19
!
! abstract: For 10-m wind speed observations
! 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
!
! program history log:
! 2014-03-19 pondeca
! 2014-09-16 carley - remove unused vars
! 2015-03-11 pondeca - Modify for possibility of not using obsdiag
! 2016-05-18 guo - replaced ob_type with polymorphic obsNode through type casting
! 2016-06-24 guo - fixed the default value of obsdiags(:,:)%tail%luse to luse(i)
! . removed (%dlat,%dlon) debris.
! 2016-10-07 pondeca - if(.not.proceed) advance through input file first
! before retuning to setuprhsall.f90
! 2017-02-06 todling - add netcdf_diag capability; hidden as contained code
! 2018-01-08 pondeca - addd option l_closeobs to use closest obs to analysis
! time in analysis
!
! input argument list:
! lunin - unit from which to read observations
! mype - mpi task id
! nele - number of data elements per observation
! nobs - number of observations
!
! output argument list:
! bwork - array containing information about obs-ges statistics
! awork - array containing information for data counts and gross checks
!
! attributes:
! language: f90
! machine: ibm RS/6000 SP
