<div style="overflow-wrap: break-word;">Hi Mike
<div><br>
</div>
<div>It is possible it could give worse results, but very unlikely. However its too hard for me to diagnose what is going on. There are many variables to your problem.</div>
<div><br>
</div>
<div>
<div>For ERA5 I have this in my data.exf:</div>
<div> &EXF_NML_03<br>
exf_offset_atemp = 273.15,<br>
exf_inscal_swdown = -1.0,<br>
exf_inscal_lwdown = -1.0,<br>
<br>
<div>Not sure how to help you, </div>

Recently I tried to change forcing dataset from NCEP-R1(6-hourly) to ERA5(hourly), but the results of them look so different. I compared the results of NCEP-R1 with the reanalysis data of HYCOM, and these two data look similar. </div>

Did I pick the wrong variables from ERA5? Or d<span style="margin:0px">oes this mean that higher temporal and spatial resolution atmospheric forcing ERA5 results in worse simulation results than lower resolution NCEP-R1?</span></div>
