Hello everyone, I would like to simulate the carbon flux of future climate scenarios now, but my input data is daily forcing. As far as I know, the CLM model requires 3-hour scale meteorological input data, and how should i set the input to simulate correctly. For example, how to set my meteorological forcing data and how to set any other modifications such as datm in, so that I can use daily forcing data for simulation

I looked at the clm user's guide and found this section as most closely related to your question:
Hello, I input daily-scale atmospheric forcing data through settings, but an error was reported during operation. The error message was ERROR: Longwave down sent from the atmosphere model is negative or zero. What is the reason for this? The following are related document

I'm afraid I do not know the cause of the error. In my experience, I am more likely to make successful changes to the default model by making small changes one at-a-time. In your case for example, after confirming that the default model runs without error, I might have changed the default DATM inputs to daily. If that worked, then I could replace the daily data with my alternate dataset, probably one field at-a-time to be on the safe side. These are just suggestions that may eventually lead you to the cause of the error that you are seeing.
I hope you have resolved this issue, but I happened to search the Forums today for this error to look for other threads discussing it and found one that may be helpful:

Hi everyone, I am trying to run a CLM5 simulation with ERA5 land-atmosphere forcing data at 01-degree spatial resolution. For these, I created a case using the compset below 2000_DATM%GSWP3v1_CLM50%SP_SICE_SOCN_MOSART_SGLC_SWAV_SIAC_SESP. However, my simulation fails after...
