1 2mT daytime problem in CANARI surface assimilation M. Derkova

2 ALADIN/SHMU DA: 2mT RMSE diurnal cycle (summer?) pb 00UTC 12UTC CANARI OPER

3 2m temperature score evolution: February 2012, Romania (D. Banciu) ALARO-oper: blue/magenta ALARO-assim (including surface local data – 160 synop data): red/green BIAS/RMSE

4 2m temperature score evolution: Jan- Apr 2012, Slovenia (N. Pristov) BIAS black - data assimilation red - dynamical adaptation 2m Temperature, Jan –Apr run Improved by data assimilation RMSE

5 ALADIN/SHMU canari (1) 01/08/ /01/2012 2mT analysis 00UTC CANARI OPER 2mT analysis 12UTC OPER CANARI OPER CANARI OPER CANARI

6 ALADIN/SHMU canari(2) 2mT +24h forecast from 12UTC 2mT +36h forecast from 00UTC 2mT +72h forecast from 00UTC OPER CANARI

7 ALADIN/SHMU canari (3) 2mRH +24h forecast from 12UTC 2mRH +36h forecast from 00UTC OPER CANARI

8 ALADIN/SHMU canari (4) difference of surface soil wetness in analyses between operational and parallel run for days indicated on slide no. 5 with green arrows (l eft picture when the RMSE score difference is big, right picture when scores are almost identical)
