MCIP - Precipitation

[ndaher]

Hi Megan,
Thanks for your reply.

The new files correspond to a new WRF simulation; not a restart. We reinitialized WRF every 5.5 days where the first 12 hours correspond to spin-up time and are discarded.

We just found this post where a similar issue was reported:

A question about WRF reinitial day in MCIP

@Rypo – That is correct. You cannot use the initial time from WRF for CMAQ. Most of the time, if we are using reinitialized run segments, we have some sort of overlap period (nominally 12 hours, but it does not need to be that length) that we “throw away”; in your case, the new segment would not pick up at 00 UTC, but it would instead by at 12 UTC (12 hours earlier). –Tanya

It seems that what we need to do is run mcip in 5.5-day increments that include the 12-hr WRF spin up files that we were originally discarding.
We will give this a try.

Thanks.
