3.2.2. Forcing format in NETCDF case

There is one file : FORCING.nc

Dimensions:

• time
• xx
• yy

Variables:

• time(time): units = "minutes since 1986-01-01 00:00:00" (example)

• FORC_TIME_STEP :forcing time step (s)

• LON(yy,xx) : longitude (degrees)
• LAT(yy,xx) : latitude (degrees)

• ZS(yy,xx): surface orography (m)
• UREF(yy,xx): reference height for the wind (m)
• ZREF(yy,xx): reference height for the temperature (m)

         The forcing parameters are:

• Tair(time,yy,xx) : Atmospheric temperature (K)
• Qair(time,yy,xx) : Atmospheric humidity (kg/kg)
• PSurf(time,yy,xx) : Atmospheric pressure (Pa)
• Rainf(time,yy,xx) : Rain (kg/m2/s)
• Snowf(time,yy,xx) : Snow (time,yy,xx) (kg/m2/s)
• Wind(time,yy,xx) : Wind speed (m/s)
• Wind_DIR(time,yy,xx) : Wind direction (degrees from N, clockwise)
• LWdown(time,yy,xx) : Long-wave radiation (W/m2)
• DIR_SWdown(time,yy,xx) : direct short-wave radiation (W/m2)
• SCA_SWdown(time,yy,xx) : diffuse short-wave radiation (W/m2)
• CO2air(time,yy,xx) : near surface CO2 concentration (kg/m3)
