Grib input relationship to WRF domain

PostPosted: Sat Feb 11, 2017 5:47 am
Hello all,

I am new in using WRF. I have done some simulations which have worked well. During this time, some questions have arisen.

- What is the minimum size that the mother domain (GRIB from another model dataset) in which WRF is nested, must have with respect to the WRF D01 domain?

- What is the minimum grid space that the WRF D01 domain could have with respecto to the grid space of the mother domain (GRIB from another model dataset)? For instance, if I use ERA-Interim reanalysis as input with an horizontal grid space of 0.75ยบ, what could be the minimun resolution I could run WRF based on it?
