Dear WRF users,
Can someone tell me the major difference between NAM and NARR when we
prepare input to WPS?
So far what I have found:
They both cover North America, with similar resolution.
NAM, reanalysis mode has few months delay, and it has the forecast mode.
NARR has half month delay, and you need some extra steps to prepare them
for WPS since not all required fields are there.
What is other difference? In term of WRF performance, which one is better?
