Bugfix in calculation of vertical velocity skewness. The added absolute value ! avoid negative values in the root. Negative values of w'w' can occur at the ! top or bottom of the model domain due to degrading the order of advection ! scheme. Furthermore the calculation will be the same for all advection ! schemes. ! ! 696 2011-03-18 07:03:49Z raasch ! Bugfix: Summation of Wicker-Skamarock scheme fluxes and variances for all ! threads ! ! 678 2011-02-02 14:31:56Z raasch ! Bugfix in calculation of the divergence of vertical flux of resolved scale ! energy, pressure fluctuations, and flux of pressure fluctuation itself ! ! 673 2011-01-18 16:19:48Z suehring ! Top bc for the horizontal velocity variances added for ocean runs. ! Setting the corresponding bottom bc moved to advec_ws. ! ! 667 2010-12-23 12:06:00Z suehring/gryschka ! When advection is computed with ws-scheme, turbulent fluxes are already ! computed in the respective advection routines and buffered in arrays ! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the ! numerics and to avoid unphysical kinks near the surface. ! So some if requests has to be done to dicern between fluxes from ws-scheme ! other advection schemes. ! Furthermore the computation of z_i is only done if the heat flux exceeds a ! minimum value. This affects only simulations of a neutral boundary layer and ! is due to reasons of computations in the advection scheme. ! ! 624 2010-12-10 11:46:30Z heinze ! Calculation of q*2 added ! ! 622 2010-12-10 08:08:13Z raasch ! optional barriers included in order to speed up collective operations ! ! 388 2009-09-23 09:40:33Z raasch ! Vertical profiles of potential density and hydrostatic pressure are ! calculated. ! Added missing timeseries calculation of w"q"(0), moved timeseries q* to the ! end. ! Temperature gradient criterion for estimating the boundary layer height ! replaced by the gradient criterion of Sullivan et al. (1998). ! Output of messages replaced by message handling routine. ! ! 197 2008-09-16 15:29:03Z raasch ! Spline timeseries splptx etc. removed, timeseries w'u', w'v', w'q' (k=0) ! added, ! bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr) ! (like other scalars) ! ! 133 2007-11-20 10:10:53Z letzel ! Vertical profiles now based on nzb_s_inner; they are divided by ! ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered ! velocity components and their products, procucts of scalars and velocity ! components), respectively. ! ! 106 2007-08-16 14:30:26Z raasch ! Prescribed momentum fluxes at the top surface are used, ! profiles for w*p* and w"e are calculated ! ! 97 2007-06-21 08:23:15Z raasch ! Statistics for ocean version (salinity, density) added, ! calculation of z_i and Deardorff velocity scale adjusted to be used with ! the ocean version ! ! 87 2007-05-22 15:46:47Z raasch ! Two more arguments added to user_statistics, which is now also called for ! user-defined profiles, ! var_hom and var_sum renamed pr_palm ! ! 82 2007-04-16 15:40:52Z raasch !

Initial revision ! ! ! Description: ! ------------ ! Compute average profiles and further average flow quantities for the different ! user-defined (sub-)regions. The region indexed 0 is the total model domain. ! ! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a ! ---- lower vertical index for k-loops for all variables, although strictly ! speaking the k-loops would have to be split up according to the staggered ! grid. However, this implies no error since staggered velocity components are ! zero at the walls and inside buildings. !------------------------------------------------------------------------------!
