Smoothing of SWI (soil wettness index)

During June 2002 in ALADIN/LACE forecast unrealistic spots in 2 m temperature appear, they were persistent for few days. Spots were caused by unrealistic spatial heterogenity of soil moisture. After smoothing of Soil Wetness Index (SWI), big gradients in T2m field are reduced and forecast is improved. For some points improvement is bigger than 2 °C.
