<p>These two formulas aim to calculate cloud radiative feedback by adjusted cloud radiative forcings. In formula (1), 'F' represents 'Effective Radiative Forcing (ERF)' , while in formula (2), it denotes 'instantaneous radiative forcing (IRF)'. Which definition is correct? IRF can be directly calculated, but ERF involves adjustments that cannot be obtained directly.</p>

Would think it best to give us input on where the formulas come from, if nothing else, to help people looking for such things?

Sorry. The two formulas are from https://doi.org/10.1007/s00382-022-06369-z and https://doi.org/10.1007/s00382-022-06577-7
