Yes, I recommend using lterp() instead of regrid(). But more importantly, your sdfwrite command is writing out the wrong variable — you want to write newgrid not prectot. —Jennifer

<div>Hi Justin,<br>

If you are using GrADS 2.0.0 or later, you may try the lterp function (<a href="http://cola.gmu.edu/grads/gadoc/gradfunclterp.html" target="_blank">http://cola.gmu.edu/grads/gadoc/gradfunclterp.html</a>).<br>

<div>I am trying to convert 0.625x0.5 degree gridded MERRA2 precipitation data to 1 degree gridded data. There wasn't much help online as how to do this, but the 1 degree file I made does seem to spit out data that is different from the original. I'll post
the commands I used to do this. The variable name is 'prectot':</div>
<div><br>
</div>
<div>open MERRA2_Monthly_1980-1991_Flx</div>
<div>set t 1 last</div>
<div>define prectot=prectot</div>
<div><span style="color:rgb(51,51,51);font-family:Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif;font-size:13px;background-color:rgb(250,250,250)">newgrid=regrid2(prectot,1.0)</span><br clear="all">
<div>set sdfwrite /data2/control/MERRA2_Monthly_1980-1991_Flx_1Deg_TotalPrecipitation.nc</div>
<div>sdfwrite prectot</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>I'm not sure if this was the correct way to do this or not. The contents of ncdump for the new file still suggest that it's not 1 degree, yet the values are different between the two files. I also tried to set the lat/lon for the new file to a small, fixed
value to see the grid sizes, but there was an error with the grid limits, so all values showed undefined. </div>
<div><br>
</div>
<div>Any help would be appreciated; I just want to double check to see if I converted to 1 degree correctly. <span><font color="#888888"><br>
