| 178 | | # Experiments # |
| 179 | | |
| 180 | | In the EXPERIMENTS directory the available configurations are LMDZORINCA, LMDZOR, LMDZ. In LMDZORINCA you can choose among three kind of experiments: |
| 181 | | * NMHC_AER |
| 182 | | * AER |
| 183 | | * GES |
| 184 | | |
| 185 | | ## inca.card ## |
| 186 | | |
| 187 | | ### !UserChoices Parameters ### |
| 188 | | You can manage some parameter since the inca.card file |
| 189 | | * climatological=[n/y] --> set climatological to choose if the simulation will use online 10m wind (y) or offline (no) |
| 190 | | * freq_write_chem=[time in second] --> set freq_write_chem to choose the write frequency in second for inca output (inca_avgr, forcate) |
| 191 | | * feedb=[0/1] --> heat fluxes computed with feedback corresponding to 0 = no aerosol effects, 1 = aerosol effects selected by ok_ade, ok_aie |
| 192 | | |
| 193 | | |
| 194 | | ### 10-m winds ### |
| 195 | | * There is an experiment directory for each configuration of the chemistry component: |
| 196 | | * EXPERIMENT/LMDZORINCA/NMHC_AER/ |
| 197 | | * EXPERIMENT/LMDZORINCA/AER/ |
| 198 | | * EXPERIMENT/lMDZORINCA/GES/ |
| 199 | | Each of those directories contain a config.card |
| 200 | | * If you work with an aerosol configuration (AER or NMHC_AER) you can chose to work with 10-m winds computed by the LMDZ model or read in forcing files. By default the second option is chosen. On the other hand, if you want to use the values computed by LMDZ, you must change the model by hand by setting the climatological variable to true in INCA/src/INCA_SRC/aerosol_meteo_calc.F90. |

| 202 | | __Files definition to read the 10-m winds__ |
| | 165 | ### 10 meters winds ### |
| | 166 | If you choose to use offline winds, you need to define their path in the !BoundaryFiles part of inca.card |
| | 167 | [[BR]] |
| | 168 | For Example : |
| 212 | | ### Text outputs ### |
| 213 | | In the INCA4 model version, the text outputs are not in the standard output files. They are redirected to a text file per processor. These files are concatenated at the end of the simulation to create only one inca.out file. This file is saved in the DEBUG/ archive. If the simulation fails, the file is saved in the Debug/ directory which is available in the experiment directory. |
| 214 | | |
| 215 | | ## lmdz.card ## |
| 216 | | You will find all the information needed to understand the lmdz.card file [wiki:DocImodelBlmdz here]. |
| 217 | | |
| 218 | | ### The nudged mode ### |
| 219 | | You can work in nudged mode (by forcing the winds using files read by the LMDZ model) or in climatological mode (by using the wind values computed by LMDZ). If you work in nudged mode, several forcing files are available on the subipsl shared account at TGCC : /ccc/work/cont003/subipsl/subipsl (only on Curie) |
| 220 | | * ECMWF96x95 : regridded winds in 96x95 from OPERA of ecmwf |
| 221 | | * ECMWF144x142 : regridded winds in 144x142 from OPERA of ecmwf |
| 222 | | * ECMWF320x160 : winds distributed by ecmwf (1979 to 2013) |
| 223 | | * ERAI96x95 : regridded winds in 96x95 from ERAI of ecmwf |
| 224 | | * ERAI : winds distributed by ecmwf (store on /ccc/store/cont003/subipsl/subipsl/dmf_import/ERAI/NETCDF/GLOBAL_075/4xdaily/AN_PL for year 1979 to 2011) |
| 225 | | |
| 226 | | |
| 227 | | |
| 228 | | ### adjust ### |
| 229 | | If you have a simulation which includes the INCA model, you must not use the adjust option which creates biases at the beginning of the simulation in particular for configurations with aerosols. If you didn't change the models you can use Bands files which are defined by default in the lmdz.card files. |
| 230 | | {{{ |
| 231 | | AER |

| 244 | | # The aerosol coupling and the radiative effect in LMDZORINCA # |
| 245 | | |
| 246 | | LMDZORINCA allows you to activate the aerosol impact on climate. To this end, we have used Céline Déandreis' PhD results. [[BR]] |
| 247 | | This coupling can be made in two different modes: |
| 248 | | * offline (reading the aerosols in files) |
| 249 | | * online (computing the aerosols using INCA) |
| 250 | | Different flags were introduced to manage these new options: '''aerosol_couple''' and '''flag_aerosol''' |
| 251 | | (in physiq.def). [[BR]] |
| 252 | | The aerosols you can use with offline or online coupling are : SO4, BC, POM, SS and DUST. If your coupling is offline, refer to the [DocImodelBlmdz#Informationssurleforçageradiatifparlesaérosols next] chapter. |
| 253 | | ## Flag definitions ## |
| 254 | | |
| 255 | | || '''Flag''' || '''Value'''|| '''Meaning''' || |
| 256 | | || aerosol_couple || n || offline coupling || |
| 257 | | || aerosol_couple || y || online coupling || |
| 258 | | |
| 259 | | |
| 260 | | LMDZ offers two flags to activate the radiative forcings: '''ok_ade''', '''ok_aie''' |
| 261 | | || '''Flag''' || '''Value'''|| '''Meaning''' || |
| 262 | | || ok_ade || y/n || computing (or not) the aerosol direct effect || |
| 263 | | || ok_aie || y/n || computing (or not) the aerosol indirect effect || |
| 264 | | |
| 265 | | The ok_ade and ok_aie flags are managed from lmdz.card : |
| 266 | | * AER --> aerosol_couple = y, ok_ade = y and ok_aie = n |
| 267 | | * NMHC_AER --> aerosol_couple = y, ok_ade = y and ok_aie = n |
| 268 | | * GES --> aerosol_couple = n, ok_ade = n and ok_aie = n |
| 269 | | |
| 270 | | |
| 271 | | ## Variable definitions ## |
| 272 | | You can also choose to compute the radiative forcing without their climatic impacts. In this case, you must use the '''feedb''' variable in the src/INCA_SRC/radlwsw_inca.F90 routine. If the variable equals 0 the climatic impact is not activated, if the variable equals 1 the climatic impact is activated. |
| 273 | | |
| | 178 | |
| | 179 | ### The BVOC and Surface coupling ### |
| | 180 | |
| | 181 | If you choose to activate the bvoc calcul in Orchidee (CHEMISTRY_BVOC=y in Orchidee.def) you can copy the new flux value in Inca. For this you need to modify the parameter '''!CoupOrchInca''' in inca.card. By default it will copy all bvoc flux : iso - mono - ORVOC - MBO - methanol - acetone - acetal - formal - acetic - formic - no_soil - nox - fertil_no - apinen - bpinen - limonen - myrcen - sabinen - camphen - 3caren - tbocimen - othermono - sesquiter. And iso and mono are use in inca instead of the value read in sflx.nc. [[BR]] |
| | 182 | '''WARNING''' it can only work with NMHC_AER configuration. |
| | 183 | |
| | 184 | snow, lai, veget, vegetfrac are also copy from Orchidee to Inca. You can choose to copy only these variables, for this you need to add in PARAM/inca.def the line : |
| | 185 | {{{ |
| | 186 | nbFlux_FromOrch=0 |
| | 187 | }}} |
| | 188 | |
| | 189 | If you want copy some flux, but not all the list, you need to modify your inca.def |
| | 190 | {{{ |
| | 191 | nbFlux_FromOrch=3 |
| | 192 | emi_FromOrch=ORVOC acetone bpinen |
| | 193 | }}} |
| | 194 | |
| | 195 | ## Lengths, frequencies ## |
| | 196 | We advice you to use a PeriodLength of 1 month or 1 year, and a Pack Frequency of 1 year. |
| | 197 | |
| | 198 | ## Computing centers ## |
| | 199 | LMDZORINCA is only available on TGCC computers |
