About adjusting the initial value of lake surface temperature for CLM5 single-point simulation

[Zhengjy]

I am currently doing a single point simulation using the CLM5 model, focusing specifically on Qinghai Lake. I simulated the daily data of lake temperature (variable: TLAKE) from 1979 to 2018, and selected the first time of TLAKE to compare with the observations. The results showed that there was a significant difference in the simulated lake temperature. This error is unacceptable.
To solve this problem, I planned to adjust the initial lake temperature value in the simulation and specify a suitable initial value, but I did not find where to modify it. Could you please suggest which file in the model I should modify to adjust the initial lake temperature value? I greatly appreciate your help and guidance on this matter.

In the /run directory where the model ran, you should find a lnd_in file, which should tell you what finidat was set to. If your simulation used a finidat file, then this is where the model obtained initial data, and you could modify that.

Thank you very much！
