Hi. Everyone.
I have a question about setting year_align, year_first, and year_last in datm_in. When using Ihist compset, do I need to set year_align, year_first, and year_last for datm.streams.txt.presaero.trans_1850-2000 and datm.streams.txt.co2tseries.20tr and modify the default values?
In the current case, I only set DATM_CLMNCEP_YR_START, DATM_CLMNCEP_YR_END and DATM_CLMNCEP_YR_ALIGN for the atmospheric forcing stream files.
If I want to use dynamic N deposition data (i.e. 1990-2010), I need to set stream_year_first_ndep=1990 and stream_year_last_ndep=2010 in lnd_in, right?
I found the setting about Ndep stream time like this:
  • Possible Default Values is 2101 for: {'sim_year_range': '1850-2100', 'phys': 'clm4_5', 'use_cn': '.true.'}
    is 2101 for: {'sim_year_range': '1850-2100', 'phys': 'clm5_0', 'use_cn': '.true.'}
    is 2010 for: {'sim_year': '2010', 'use_cn': '.true.'}
    is 2000 for: {'sim_year': '2000', 'use_cn': '.true.'}
    is 1850 for: {'sim_year': '1850', 'use_cn': '.true.'}
    is 2000 for: {'sim_year': '1000', 'use_cn': '.true.'}
    is 2000 for: {'sim_year': 'constant', 'sim_year_range': '1000-1002', 'use_cn': '.true.'}
    is 2000 for: {'sim_year': 'constant', 'sim_year_range': '1000-1004', 'use_cn': '.true.'}
I am a little confused. Looking forward to the solutions. Thanks.

When you create an IHist case, all these things should be set for you, so that you should not need to change them.
