4# *Station Air-Sea Fluxes* demonstration case

6## Objectives
7
8```STATION_ASF``` is a demonstration case that mimics an in-situ station (buoy, platform) dedicated to the estimation of surface air-sea fluxes by means of the measurement of traditional meteorological surface parameters.
9
10```STATION_ASF``` is based on the merging of the "single column" and the "standalone surface module" configurations of NEMO (C1D meets SAS). As such, the spatial domain of ```STATION_ASF``` is punctual (1D).
11
12```STATION_ASF``` is therefore a very light and versatile tool to test the different bulk algorithms and cool-skin/warm-layer parameterizations included in NEMO.
13
14As input ```STATION_ASF``` will require the sea surface parameters:
15
16- bulk sea surface temperature (SST) at $z_{SST}$ meters below the surface
17- Surface current vector
18- Sea surface salinity
19
20as well as the usual surface atmospheric state:
21
22- air temperature at $z_t$ meters above the surface
23- air humidity  at $z_t$ meters above the surface (specific humidity or relative humidity or dew-point temperature)
24- wind speed vector at $z_u$ meters above the surface
25- Sea level atmospheric pressure (SLP)
26- Downwelling solar radiation
27- Downwelling longwave radiation

35### Important namelist parameters speficic to STATION_ASF
36
37* ```rn_dept1@namusr_def:``` depth (m) at which the prescribed SST is taken (i.e. depth of first T-point); important due to impact on warm-layer estimate, the deeper, the more pronounced!
38
39* ```rn_lat1d,rn_lon1d@namc1d:``` fixed coordinates of the location of the station (buoy, platform, etc).
40
41* ```namsbc_blk:``` to be filled carefully, just as for "C1D", the prescribed surface ATMOSPHERIC state (files) are time series of shape 3x3 in space
42
43* ```namsbc_sas:``` to be filled carefully, just as for "C1D", the prescribed surface OCEAN state (files) are time series of shape 3x3 in space

54- ```Station_PAPA_50N-145W_atm_hourly.nc```  → contains hourly surface atmospheric state
55- ```Station_PAPA_50N-145W_precip_daily.nc``` → contains daily precipitation
56- ```Station_PAPA_50N-145W_oce_hourly.nc``` → contains hourly sea surface state
