In your example below, you have regrid2(slp,1,1,2,2). The syntax should
be regrid2(some grads variable, delta x, delta y, a string defining the
type of averaging, then two numbers that depend on the preceding
string). So, in your case, regrid2 is trying to regrid slp onto a 1x1
degree grid, but then encounters a "2" instead of a character string.
Do you want to do something special here? If all you want is a 1x1
degree regrid, I suggest trying "regrid2(slp,1,1)". Finally, you should
have a file in the UDF directory called regrid2.txt that explains this
in more detail.
