The period 1990-2000 has been simulated using the WRF model over the Iberian Peninsula with 15km horizontal resolution. The WRF model was nested inside the ERA40 Reanalysis. Two integrations with WRF have been carried out. In the first one (NO_DA), the mesoscale model received reanalysis information through the boundaries of the domain. In the second one (IPRA), 3DVAR assimilation of surface variables, air reports and vertical soundings has been carried out every 12 hours (00Z and 12Z). The observations assimilated into the mesoscale integrations are the ones tagged as error-free in the analysis feedback files. Results shown explore the differences found between the two simulations regarding surface temperature or precipitation at the different seasons of the year. The most remarkable difference found implies that assimilation of observations leads to a clearly improved representation of surface temperature over land areas, correcting the summer cold bias observed on the model outputs over the area.
