The time stamp of landuse.timeseries in IHIST

[xiaoxiaokuishu]

Hi, all,
I create a IHIST case with the simulation period from 1999-2001, but when I check the logfile, I find the

It seems the model get the PCT_XX information from 1998? But my simulation is start from 1999.

I'm just hypothesizing here: If this is the beginning of the simulation, then maybe the model uses previous year data in the first time step. If this is not the case, then maybe you need to adjust settings in env_run.xml to:
DATM_YR_ALIGN = 1999
DATM_YR_START = 1999
or something else that you may find works better.
