◆ volgrid6d_recompute_stat_proc_diff()

subroutine volgrid6d_class_compute::volgrid6d_recompute_stat_proc_diff ( type(volgrid6d), intent(inout)  this,
type(volgrid6d), intent(out)  that,
integer, intent(in)  stat_proc,
type(timedelta), intent(in)  step,
logical, intent(in), optional  full_steps,
type(datetime), intent(in), optional  start,
logical, intent(in), optional  clone 
)

Specialized method for statistically processing a set of data already processed with the same statistical processing, on a different time interval.

This method performs statistical processing by difference of different intervals. Data with both analysis/observation or forecast timerange are processed.

The output that volgrid6d object contains elements from the original volume this satisfying the conditions

Output data will have timerange of type stat_proc and p2 = step. The supported statistical processing methods (parameter stat_proc) are:

  • 0 average
  • 1 accumulation
  • 4 difference

Input volume may have any value of thistime_definition, and that value will be conserved in the output volume.

Parametri
[in,out]thisvolume providing data to be recomputed, it is not modified by the method, apart from performing a volgrid6d_alloc_vol on it
[out]thatoutput volume which will contain the recomputed data
[in]stat_proctype of statistical processing to be recomputed (from grib2 table), only data having timerange of this type will be recomputed and will appear in the output volume
[in]steplength of the step over which the statistical processing is performed
[in]full_stepsif provided and .TRUE., process only data having processing interval (p2) equal to a multiple of step
[in]startif provided, together with full_steps, processes data on intervals starting at start +- an integer amount of step intervals
[in]cloneif provided and .TRUE. , clone the gaid's from this to that
