Hi, all

Suppose that I have prepared a series of wrfchemi with 8 files per day which are at the time of 01:30,4:30,7:30,10:30,...

Since I used the FNL as the meteorological input, it seems that if I set the `start_date` in namelist as e.g. 2017-07-01_01:30:00,
the ungrib would occur errors, but with the hour as 00:00,06:00,12:00,18:00, it is normal.

However, in this case, the start time of wrfinput and wrfchemi is not equal(00:00 vs 01:30), it would report some error when the wrf.exe is finding the `auxinput5` file.

Is there some method can fix this problem. Can we input the wrfchemi after wrf.exe have run a couple of times?
