<p>Dear all,
<br />
<br />I am trying to calculate mean between product 1 (2.8X2.8 degree of resolution), product 2 (2.8X2.8 degree of resolution) and product 3 (1X1 degree resolution). I do not know how to increase the resolution of product 3 to 2.8X2.8 degree.</p>
<p>Regards

<br />> Your best bet would be use use the extension re() or the older regrid2() UDF with the box-averaging method. Documentation for re() is here:

<br />> None of these are yet available with GrADS v2. The built in lterp() function in GrADS v2 will very likely introduce aliasing when going to a much lower resolution, so I'd not recommend it.
