    108## Objectives 
    … …  
    1816As input ```STATION_ASF``` will require the traditional *bulk* sea surface parameters: 
    1917 
    20 - sea surface temperature (SST) at $z_{SST}$ meters below the surface 
     18- Bulk sea surface temperature (SST) at _z<sub>SST</sub>_ meters below the surface 
    2119- Surface current vector 
    2220- Sea surface salinity 
    … …  
    2422as well as the usual surface atmospheric state: 
    2523 
    26 - air temperature at $z_t$ meters above the surface 
    27 - air humidity  at $z_t$ meters above the surface (specific humidity or relative humidity or dew-point temperature) 
    28 - wind speed vector at $z_u$ meters above the surface 
     24- air temperature at _z<sub>t</sub>_ meters above the surface 
     25- air humidity  at _z<sub>t</sub>_ meters above the surface (specific humidity or relative humidity or dew-point temperature) 
     26- wind speed vector at _z<sub>u</sub>_ meters above the surface 
    2927- Sea level atmospheric pressure (SLP) 
    3028- Downwelling solar radiation 
    3129- Downwelling longwave radiation

    51 Three full years of processed hourly data from the PAPA station (buoy) can be downloaded here: 
    52 https://drive.google.com/file/d/1MxNvjhRHmMrL54y6RX7WIaM9-LGl--ZP/ 
     60One full year (2018) of processed hourly data from the PAPA station (buoy) is found into the `input_data` directory. 
     61These three files are everything you need to play with the set of *namelists* provided for this test-case.

    56 - ```Station_PAPA_50N-145W_atm_hourly.nc```  → contains hourly surface atmospheric state 
    57 - ```Station_PAPA_50N-145W_precip_daily.nc``` → contains daily precipitation 
    58 - ```Station_PAPA_50N-145W_oce_hourly.nc``` → contains hourly sea surface state 
     63- ```Station_PAPA_50N-145W_atm_hourly_y2018.nc```  → contains hourly surface atmospheric state 
     64- ```Station_PAPA_50N-145W_precip_daily_y2018.nc``` → contains daily precipitation 
     65- ```Station_PAPA_50N-145W_oce_hourly_y2018.nc``` → contains hourly sea surface state

    6067For station PAPA (50.1 N, 144.9 W), air temperature and humidity are measured at 2.5 m, the wind speed at 4 m, and the SST at 1 m below the surface, hence the following namelist parameters are given: 
    6168 
    62 - ```rn_dept1 =    1.  ``` (&namusr_def) 
    63 - ```rn_lat1d =  50.1 ``` (&namc1d) 
    64 - ```rn_lon1d = 215.1``` (&namc1d) 
    65 - ```rn_zqt   =   2.5``` (&namsbc_blk) 
    66 - ```rn_zu    =    4.``` (&namsbc_blk) 
     69- `&namusr_def` 
     70  - ```rn_dept1 =    1.  ``` 
     71- `&namc1d` 
     72  - ```rn_lat1d =  50.1 ``` 
     73  - ```rn_lon1d = 215.1``` 
     74- `&namsbc_blk` 
     75  - ```rn_zqt   =   2.5``` 
     76  - ```rn_zu    =    4.``` 
    6777 
    6878 
    … …  
    7282First compile the test-case as follows (compile with xios-2.5 support → check your ARCH file): 
    7383 
    74 ```./makenemo -m <your_arch> -n STATION_ASF -j 4 -a STATION_ASF``` 
     84```./makenemo -a STATION_ASF -m <your_arch> -n STATION_ASF2 -j 4``` 
    7585 
    7686Then you can use the script ``launch_sasf.sh`` found in  ```EXPREF/``` to launch 3 simulations (one for each bulk parameterization available). You need to adapt the following variable to your environment in the script: 
    7787 
    78 - ```NEMO_DIR``` : NEMO root directory where to fetch compiled STATION_ASF ```nemo.exe``` + setup (such as ```${NEMO_DIR}/tests/STATION_ASF```) 
     88- ```NEMO_ROOT_DIR``` : NEMO root directory where to fetch compiled STATION_ASF ```nemo.exe``` + setup (such as ```${NEMO_ROOT_DIR}/tests/STATION_ASF```) 
    7989 
    80 - ```WORK_DIR``` :  Directory where to run the simulation 
     90- ```PROD_DIR``` :  Directory where to run the simulation 
    8191 
    82 - ```FORC_DIR``` Directory containing sea-surface + atmospheric forcings (get it there https://drive.google.com/file/d/1MxNvjhRHmMrL54y6RX7WIaM9-LGl--ZP/) 
     92- ```DATA_IN_DIR``` : Directory containing sea-surface + atmospheric forcings (get it there https://drive.google.com/file/d/1MxNvjhRHmMrL54y6RX7WIaM9-LGl--ZP/) 
    8393 
     94If everything goes according to plan, ``launch_sasf.sh`` should have generated the 3 following sets of output files into `${PROD_DIR}/output`: 
     95 
     96    STATION_ASF-COARE3p6_1h_20180101_20181231_gridT.nc 
     97    STATION_ASF-COARE3p6_1h_20180101_20181231_gridU.nc  
     98    STATION_ASF-COARE3p6_1h_20180101_20181231_gridV.nc  
     99    STATION_ASF-ECMWF_1h_20180101_20181231_gridT.nc  
     100    STATION_ASF-ECMWF_1h_20180101_20181231_gridU.nc  
     101    STATION_ASF-ECMWF_1h_20180101_20181231_gridV.nc  
     102    STATION_ASF-NCAR_1h_20180101_20181231_gridT.nc  
     103    STATION_ASF-NCAR_1h_20180101_20181231_gridU.nc  
     104    STATION_ASF-NCAR_1h_20180101_20181231_gridV.nc
