[gradsusr] Random Missing Values Grid Cells Using Cressman Analysis

[Perry, Aaron]

Good Morning All,


I am producing a contoured layer via Cressman interpolation in GrADS.


I'm running into a problem where I'm seeing random grid cells with missing values over areas that really should have contouring. I know that a Cressman interpolation is based upon radial interpolation so, my input values may be off slightly for my station spacing.


GrADS Code:


'define temp = oacres(dummy.1(t=1),temp.2(t=1),12,10,7,4,2,1)'
