About grid size of the mother domain

Post by lcana » Tue Feb 07, 2017 12:04 pm

Hi all,
I'll try to perform a reanalysys of an event using ERA INTERIM ECMWF data (0.7x0.7, from 2007).
I'd like to know which should be the dx parameter for the mother domain. Half the grid size of the data? The center of the domain is 28º, so 39 Km would be a good start?

Thanks,

Luis

Hello, whatever you chose but difference from input resolution should not exceed ~5x to avoid big boundary errors.
