    4545In access 1.3 there was a good agreement between the SCM net flux and the soil temperature change, though for some reason the agreement with GA is poorer (is the soil temperature changing again after stempv?). In 10.6 CABLE seems to be losing about 5 W/m^2^.

     47The UM has a net radiation on tiles diagnostic that was not saved by the SCM for some reason so I added it. In both JULES and CABLE this uses the updated surface temperature to calculate the upward LW, so should better match the soil temperature change.

     49|| || JULES  || CABLE ||
     50|| Grid box net radiation || 95.14 || 73.19 ||
     51|| Tile net radiation || 95.12 || 67.45 ||
     52|| Tile net flux || 4.40 || 5.13 ||
     53|| Soil change || 4.36 || 5.18 ||

     55Therefore it seems that using the radnet_tile diagnostic the energy balance is equally good in JULES and CABLE. However this isn't the flux that the atmosphere uses.
