Thank you very much for your response. Yes, Martin helped a lot and now the problem is solved.</div>

<div style="line-break:after-white-space">Hi FL, I have not followed this discussion (and perhaps Martin or Matt have already suggested/check this) but one place to look is your data.exf file. Did you correctly specify the contents of your ERA5_sw_3hrs_1993.bin
file? If you send (or resend?) your data.cal and data.exf files, I can take a quick look.

I don’t know what to suggest, with your parameter settings you should get time dependent forcing. Run the model with a higher debugLevel > 3 and try to figure out from the STDOUT, what’s going on. </span>

Thanks a lot for your reply. I made a mistake in my previous email, actually EXFatemp diagnostics also remains unchanged with time, so the model actually reads only the first record of my external forcing. It is because EXFlwqnet is calculated with seawater
temperature which varies, so the EXFlwqnet is changing. I really do not know why the model only reads the first record of my forcing file. I tested the forcing file in matlab as follows:</div>
