Problems with data in 3DVAR.

Wind output get worse with smaller domains

Hi friends

I am new in WRF, so I don´t know if it´s usual what I am experiencing. Everything seems to work fine, however when I compare the wind output of WRF with the real measurements, I notice that the best correlation is with the coarsest domain. I mean, the domains d02 and d03 with 15 and 5 km resolution respectively show worse correlation and RMSE than the domain d01 (45 km resolution), which is the only one that improve the correlation with regard the input data of ERA-Interim. So I thought I was doing wrongly the nesting, but after several tries, nothing seems to change this situation. Is it usual or do you think I am doing something wrong?

Thanks in advance
