wetdepo Subroutine

public subroutine wetdepo(itime, ltsample, loutnext)

                                                                        *

Calculation of wet deposition using the concept of scavenging coefficients.* For lack of detailed information, washout and rainout are jointly treated. * It is assumed that precipitation does not occur uniformly within the whole * grid cell, but that only a fraction of the grid cell experiences rainfall. * This fraction is parameterized from total cloud cover and rates of large * scale and convective precipitation. * * Author: A. Stohl * * 1 December 1996 * * Correction by Petra Seibert, Sept 2002: * use centred precipitation data for integration * Code may not be correct for decay of deposition! * * 2021 Andreas Plach: - moved backward wet depo. calc. here from timemanager * - bugfix in-cloud scavenging * * PS, AP 2021: followed up on some variable renaming and * corrected get_wetscav subroutine parameter list *

                                                                        *

Variables: * ix,jy indices of output grid cell for each particle * itime [s] actual simulation time [s] * jpart particle index * ldeltat [s] interval since radioactive decay was computed * loutnext [s] time for which gridded deposition is next output * loutstep [s] interval at which gridded deposition is output * ltsample [s] interval over which mass is deposited * wetdeposit mass that is wet deposited * wetgrid accumulated deposited mass on output grid * wetscav scavenging coefficient * * Constants: * *

CALCULATE DEPOSITION

Sabine Eckhardt, June 2008 create deposition only for forward runs Add the wet deposition to accumulated amount on output grid and nested output grid
