Note: HRES and Ensemble Control Forecast are scientifically, structurally and computationally identical. With effect from Cy49r1, Ensemble Control Forecast output is equivalent to HRES output where shown in the diagrams. At the time of the diagrams, HRES had resolution of 9km and ensemble members had a resolution of 18km.

However, generally there is an improvement in forecast 2m temperatures. But at times the analysed temperature structure of the boundary layer may only move a small way towards correcting errors in the background (Fig9.2.1-1). From a mathematical standpoint it is also (unfortunately!) more difficult to correctly assimilate data near the surface than data higher up.
See also Section 2.1.4.5 Modelling soil structure.
Fig9.2.1-1: Examples of the difficulty of assimilating temperature and humidity data in the lowest layers.
