84	! - Implement offline nesting for salsa

93	!
94	! 4268 2019-10-17 11:29:38Z schwenkel
95	! Moving module specific boundary conditions from time_integration to module
96	!
97	! 4256 2019-10-07 10:08:52Z monakurppa

100	! 4227 2019-09-10 18:04:34Z gronemeier
101	! implement new palm_date_time_mod
102	!
103	! 4226 2019-09-10 17:03:24Z suehring
104	! Netcdf input routine for dimension length renamed
105	!
106	! 4182 2019-08-22 15:20:23Z scharf
107	! Corrected "Former revisions" section
108	!
109	! 4167 2019-08-16 11:01:48Z suehring
110	! Changed behaviour of masked output over surface to follow terrain and ignore
111	! buildings (J.Resler, T.Gronemeier)
112	!
113	! 4131 2019-08-02 11:06:18Z monakurppa
114	! - Add "salsa_" before each salsa output variable
115	! - Add a possibility to output the number (salsa_N_UFP) and mass concentration
116	! (salsa_PM0.1) of ultrafine particles, i.e. particles with a diameter smaller
117	! than 100 nm
118	! - Implement aerosol emission mode "parameterized" which is based on the street
119	! type (similar to the chemistry module).
120	! - Remove unnecessary nucleation subroutines.
121	! - Add the z-dimension for gaseous emissions to correspond the implementation
122	! in the chemistry module
123	!
124	! 4118 2019-07-25 16:11:45Z suehring
125	! - When Dirichlet condition is applied in decycling, the boundary conditions are
126	! only set at the ghost points and not at the prognostic grid points as done
127	! before
128	! - Rename decycle_ns/lr to decycle_salsa_ns/lr and decycle_method to
129	! decycle_method_salsa
130	! - Allocation and initialization of special advection flags salsa_advc_flags_s
131	! used for salsa. These are exclusively used for salsa variables to
132	! distinguish from the usually-used flags which might be different when
133	! decycling is applied in combination with cyclic boundary conditions.
134	! Moreover, salsa_advc_flags_s considers extended zones around buildings where
135	! the first-order upwind scheme is applied for the horizontal advection terms.
136	! This is done to overcome high concentration peaks due to stationary numerical
137	! oscillations caused by horizontal advection discretization.
138	!
139	! 4117 2019-07-25 08:54:02Z monakurppa
140	! Pass integer flag array as well as boundary flags to WS scalar advection
141	! routine
142	!
143	! 4109 2019-07-22 17:00:34Z suehring
144	! Slightly revise setting of boundary conditions at horizontal walls, use
145	! data-structure offset index instead of pre-calculate it for each facing
146	!
147	! 4079 2019-07-09 18:04:41Z suehring
148	! Application of monotonic flux limiter for the vertical scalar advection
149	! up to the topography top (only for the cache-optimized version at the
150	! moment).
151	!
152	! 4069 2019-07-01 14:05:51Z Giersch
153	! Masked output running index mid has been introduced as a local variable to
154	! avoid runtime error (Loop variable has been modified) in time_integration
155	!
156	! 4058 2019-06-27 15:25:42Z knoop
157	! Bugfix: to_be_resorted was uninitialized in case of s_H2O in 3d_data_averaging
158	!
159	! 4012 2019-05-31 15:19:05Z monakurppa
160	! Merge salsa branch to trunk. List of changes:
161	! - Error corrected in distr_update that resulted in the aerosol number size
162	! distribution not converging if the concentration was nclim.
163	! - Added a separate output for aerosol liquid water (s_H2O)
164	! - aerosol processes for a size bin are now calculated only if the aerosol
165	! number of concentration of that bin is > 2*nclim
166	! - An initialisation error in the subroutine "deposition" corrected and the
167	! subroutine reformatted.
168	! - stuff from salsa_util_mod.f90 moved into salsa_mod.f90
169	! - calls for closing the netcdf input files added
170	!
171	! 3956 2019-05-07 12:32:52Z monakurppa
172	! - Conceptual bug in depo_surf correct for urban and land surface model
173	! - Subroutine salsa_tendency_ij optimized.
174	! - Interfaces salsa_non_advective_processes and salsa_exchange_horiz_bounds
175	! created. These are now called in module_interface.
176	! salsa_exchange_horiz_bounds after calling salsa_driver only when needed
177	! (i.e. every dt_salsa).
178	!
179	! 3924 2019-04-23 09:33:06Z monakurppa
180	! Correct a bug introduced by the previous update.
181	!
182	! 3899 2019-04-16 14:05:27Z monakurppa
183	! - remove unnecessary error / location messages
184	! - corrected some error message numbers
185	! - allocate source arrays only if emissions or dry deposition is applied.
186	!
187	! 3885 2019-04-11 11:29:34Z kanani
188	! Changes related to global restructuring of location messages and introduction
189	! of additional debug messages
190	!
191	! 3876 2019-04-08 18:41:49Z knoop
192	! Introduced salsa_actions module interface
193	!
194	! 3871 2019-04-08 14:38:39Z knoop
195	! Major changes in formatting, performance and data input structure (see branch
196	! the history for details)
197	! - Time-dependent emissions enabled: lod=1 for yearly PM emissions that are
198	! normalised depending on the time, and lod=2 for preprocessed emissions
199	! (similar to the chemistry module).
200	! - Additionally, 'uniform' emissions allowed. This emission is set constant on
201	! all horisontal upward facing surfaces and it is created based on parameters
202	! surface_aerosol_flux, aerosol_flux_dpg/sigmag/mass_fracs_a/mass_fracs_b.
203	! - All emissions are now implemented as surface fluxes! No 3D sources anymore.
204	! - Update the emission information by calling salsa_emission_update if
205	! skip_time_do_salsa >= time_since_reference_point and
206	! next_aero_emission_update <= time_since_reference_point
207	! - Aerosol background concentrations read from PIDS_DYNAMIC. The vertical grid
208	! must match the one applied in the model.
209	! - Gas emissions and background concentrations can be also read in in salsa_mod
210	! if the chemistry module is not applied.
211	! - In deposition, information on the land use type can be now imported from
212	! the land use model
213	! - Use SI units in PARIN, i.e. n_lognorm given in #/m3 and dpg in metres.
214	! - Apply 100 character line limit
215	! - Change all variable names from capital to lowercase letter
216	! - Change real exponents to integer if possible. If not, precalculate the value
217	! value of exponent
218	! - Rename in1a to start_subrange_1a, fn2a to end_subrange_1a etc.
219	! - Rename nbins --> nbins_aerosol, ncc_tot --> ncomponents_mass and ngast -->
220	! ngases_salsa
221	! - Rename ibc to index_bc, idu to index_du etc.
222	! - Renamed loop indices b, c and sg to ib, ic and ig
223	! - run_salsa subroutine removed
224	! - Corrected a bud in salsa_driver: falsely applied ino instead of inh
225	! - Call salsa_tendency within salsa_prognostic_equations which is called in
226	! module_interface_mod instead of prognostic_equations_mod
227	! - Removed tailing white spaces and unused variables
228	! - Change error message to start by PA instead of SA
229	!
230	! 3833 2019-03-28 15:04:04Z forkel
231	! added USE chem_gasphase_mod for nvar, nspec and spc_names
232	!
233	! 3787 2019-03-07 08:43:54Z raasch
234	! unused variables removed
235	!
236	! 3780 2019-03-05 11:19:45Z forkel
237	! unused variable for file index removed from rrd-subroutines parameter list
238	!
239	! 3685 2019-01-21 01:02:11Z knoop
240	! Some interface calls moved to module_interface + cleanup
241	!
242	! 3655 2019-01-07 16:51:22Z knoop
243	! Implementation of the PALM module interface

252	! ------------
253	!> Sectional aerosol module for large scale applications SALSA
254	!> (Kokkola et al., 2008, ACP 8, 2469-2483). Solves the aerosol number and mass
255	!> concentration as well as chemical composition. Includes aerosol dynamic
256	!> processes: nucleation, condensation/evaporation of vapours, coagulation and
257	!> deposition on tree leaves, ground and roofs.
258	!> Implementation is based on formulations implemented in UCLALES-SALSA except
259	!> for deposition which is based on parametrisations by Zhang et al. (2001,
260	!> Atmos. Environ. 35, 549-560) or Petroff&Zhang (2010, Geosci. Model Dev. 3,
261	!> 753-769)
262	!>
263	!> @todo Apply information from emission_stack_height to lift emission sources
264	!> @todo Allow insoluble emissions
