| 134 || GLOMAP-mode impaction scavenging routine ukca_impc_scav affected by the rate of aerosol removal by rainfall || [https://code.metoffice.gov.uk/trac/um/ticket/6419 UM:#6419] || || vn10.3+ || || A bug has been identified in the GLOMAP-mode impaction scavenging routine ukca_impc_scav that affects the rate of aerosol removal by rainfall. It is contained within code executed when the temporary logical l_fix_ukca_impscav is set to true. That code was introduced as a fix for two other bugs by #1421. <br/> The problem is caused by a mismatch of conditions under which the working variable interzz is (a) calculated and (b) used. Both (a) and (b) occur within the iprecip loop that loops over the two rainfall types (convective and large-scale). However, the use (b) occurs if totrain(jl) > 0.0 while the calculation (a) occurs in a preceeding nbox loop only if allrain(iprecip,jl) > 0.0. This will only work if both rainfall types are non-zero or both are zero. <br/> If convective rain is zero but total rain is not, scavenging associated with convective rain may still be non-zero, calculated using an un-initialised interzz value (potentially a non-zero compile-time value or the value from a previous call). Likewise, if large-scale rain is zero but total rain is not then scavenging associated with large-scale rain may still be non-zero, calculated using the interzz value for convective rain from the previous iteration of the precip loop. <br/> This bug was discovered during LFRic testing when the use of an un-initialised value caused the model to crash when UKCA was switched on in the proto_gal7 configuration. <br/> The bug can be fixed by using the allrain(iprecip,jl) > 0.0 condition in both nbox loops. || CLOSED || John Hemmings |

119 | Incorrect calculation for gridbox area - only affects GLOMAP-mode diagnostics | um:#5506 | ALL versions | None yet | Calculation of volume appears correct, but area is not. This calculation is missing the factor fv_cos_theta_latitude so will not cause area to tend towards zero at the poles. It also seems to use an unnecessary approximation to the latitude difference (based on sinv_latitude ) which may break down at high latitudes. The calculation should perhaps be consistent with subsequent volume calculation but without the delta_r factor. This will likely only affect diagnostics calculated in ukca_emiss_diags_mode , where it is used to convert from kg/m2/s to mol/gridbox/s, although it is also printed out in ukca_aero_ctl . Not actually a bug, but is inconsistent between volume & area calculations. Take off as a bug. May be related to mass to calculation differences. Will be moved outside to the parent model. |

130 | Bug in aerosol dry deposition when using 27 surface types in JULES | Partially fixed using UM:#5622 UM:#6088 |
All versions | The bug exists because of an erroneous dependency on the array size NTYPE (from JULES_SURFACE_TYPES_MOD) in subroutines UKCA_DDEPAER and UKCA_DDEPAER_INCL_SEDI. This is not appropriate because most of the processing is not written to be dependent on the surface types being used in JULES. A surface type at each location is instead inferred (in UKCA_AERO_CTL) from the roughness length and its index is held in the array ILSCAT. The index values are intended to be interpreted with reference to the JULES 9 type scheme. Only the values 1, 3, 7 and 9 are used, corresponding to forest, grassland, water and ice respectively. The indices are used to access arrays YR, CR and ALPHA that are set up in these aerosol dry deposition routines. The arrays should therefore always be of size 9 with values based on the 9 type scheme, irrespective of the JULES NTYPE value. However, alternative, incompatible arrays are set up if NTYPE is 13, 17 or 27. These were presumably intended to be accessed using the type indices consistent with the other JULES schemes but are actually accessed with the 9-type scheme indices available in ILSCAT. Inappropriate values will therefore be obtained when NTYPE is not 9. Note that Ticket UM:#5622 will fix the bug when interactive dry deposition is not used in the chemistry or when NTYPE in JULES is 13 or 17 but will not fix it when interactive dry deposition is selected (L_UKCA_INTDD = .TRUE.) and NTYPE is 27. Fixing it for NTYPE = 27 will change results so will require a separate bug fix ticket with appropriate testing and approval. |

131 | Invalid surface roughness input to aerosol dry deposition over land | UM:#6088 | All versions | In the UM, UKCA uses the roughness length with stash code 00026 to infer the surface type for aerosol dry deposition (and for the old non-interactive gas dry deposition scheme). However, this value is only valid over the sea. It seems to be set to 0.5 over the land from the UM data I’ve looked at. This seems to be simply a filler value with no scientific significance. As a consequence of the 0.5 value, the UKCA aerosol dry deposition routines categorise all land as forest in the UM runs (routine ukca_aero_ctl uses z0>0.1m for forest). This will interact with bug #130 in aerosol dry deposition (see above) that occurs when using any number of surface types in JULES other than 9. | Closed | Mohit Dalvi | ||

134 | GLOMAP-mode impaction scavenging routine ukca_impc_scav affected by the rate of aerosol removal by rainfall | UM:#6419 | vn10.3+ | A bug has been identified in the GLOMAP-mode impaction scavenging routine ukca_impc_scav that affects the rate of aerosol removal by rainfall. It is contained within code executed when the temporary logical l_fix_ukca_impscav is set to true. That code was introduced as a fix for two other bugs by #1421. The problem is caused by a mismatch of conditions under which the working variable interzz is (a) calculated and (b) used. Both (a) and (b) occur within the iprecip loop that loops over the two rainfall types (convective and large-scale). However, the use (b) occurs if totrain(jl) > 0.0 while the calculation (a) occurs in a preceeding nbox loop only if allrain(iprecip,jl) > 0.0. This will only work if both rainfall types are non-zero or both are zero. If convective rain is zero but total rain is not, scavenging associated with convective rain may still be non-zero, calculated using an un-initialised interzz value (potentially a non-zero compile-time value or the value from a previous call). Likewise, if large-scale rain is zero but total rain is not then scavenging associated with large-scale rain may still be non-zero, calculated using the interzz value for convective rain from the previous iteration of the precip loop. This bug was discovered during LFRic testing when the use of an un-initialised value caused the model to crash when UKCA was switched on in the proto_gal7 configuration. The bug can be fixed by using the allrain(iprecip,jl) > 0.0 condition in both nbox loops. |

144 | interchangeable use of specific humidity and water vapour mixing ratio | #6813 | all configurations affected | UKCA includes calculations of relative humidity, clear-sky relative humidity and saturation vapour pressure. Relative humidity calculations should be based on water vapour mass mixing ratio but are in part based on specific humidity. Also, the calculation of saturation vapour pressure is derived from saturation mixing ratio but uses a formula for deriving SVP from saturation specific humidity. This interchangeable use of specific humidity (ratio for moist air) and mixing ratio (ratio for dry air) in existing configurations introduces small numerical errors in UM and LFRic model runs. These bugs were identified at UM version vn12.2 and have been highlighted by comments in code lodged with UM ticket #6660 (in ukca_main1-ukca_main1.F90 and atmos_ukca_humidity_mod.F90).

148 | There is a bug in the UKCA Abdul-Razzak Ghan droplet activation scheme whereby the weighted mean hygroscopicity of the internally mixed aerosols within a given mode is calculated incorrectly if there is more than one soluble aerosol composition type present (e.g., sulphate and sea-salt), with the hygroscopicity being underestimated – this will lead too few droplets being activated. | ukca:#106 um:#6174 |
always | The underestimate gets worse as the mass of the two soluble components become equal, and as the mass of the insoluble aerosol diminishes. The ticket also introduces new values for the hygroscopicities for sulphate and organic carbon. It could be argued that the use of the old values also represents a bug since the model previously assumed a zero hygroscopicity of organic carbon and a too-high value for sulphate. Or these could be more considered value changes. Fixed at vn13.3 |

149 | There is a bug that causes the wrong photolysis rate field to be output for the JNO2 diagnostic when using the CRISTRAT scheme. This results from an indexing problem in photol_diags in ukca_um_photol_ctl_mod.F90 (UM vn13.2) causing the wrong photolysis rate field to be output. | ukca:#29 um:#7205 |
Since vn11.4 um:#4231 | In lines 641-667, the loop used to find the index for accessing the required field data in ‘photol_rates’ relies on finding the position of the ‘jno2’ label in the ratj_varnames array and does not stop searching until the end of the array. In the CRISTRAT scheme there are multiple ‘jno2’ labels with different quantum yields and only one (with yield = 100%) is the correct one for the NO2 reaction. The others are for different reactions whose rates are derived from that. The index selected will be the last of the ‘jno2’ entries which is for the wrong reaction when there are multiple entries. The same processing is used for other photolysis rate labels but I don’t think these have multiple entries. The ratj_varnames array referred to above is returned by a call to the ukca_get_photol_reaction_data API routine (dummy argument varnames_ptr). It holds the fname component of the ratj_defs structure for each photolysis reaction in the chemistry scheme. The inline documentation for this routine in ukca_chem_defs_mod.F90 does not indicate that the list returned may contain duplicates. This should be made clear to reduce the risk of misuse in future. The bug will be corrected by UKCA:#29 and linked UM ticket #7205. These tickets will remove the existing UM-side code for the photolysis rate diagnostics and replace it with code using the new UKCA diagnostic handling scheme. This will access jrates after their input to UKCA as environmental driver data not before and it uses a more robust method to index the correct fields. |
