[gradsusr] reanalysis topographic masking

[Andrew Friedman]

Hi GrADS users,

I'm trying mask out topography below certain pressure levels when plotting North American Regional Reanalysis (NARR)  winds. Do any of you know where to find NARR elevation, or how to convert the elevation to pressure levels in GrADS?

Though I'm specifically interested in NARR, suggestions based on experience with other reanalysis products would be helpful too.

Thanks much,
Andrew
