One thing that will help you to compare your plots is to use the same contour levels. Notice that the regridded data is on a scale from 0.45 to 1.05 and the original data is from 0 to 2.8. I think that we are seeing different features in the two plots. Set the contour levels with the /LEV qualifier and use the same levels for both.
To make a plot of a subset of the data, do it like this for a variableVV with coordinate variables long and lat
FILL VV[i=1:51,j=1:51], long[i=1:51,j=1:51], lat[i=1:51,j=1:51]

Hi everyone, I try to use the external function to interpolate data from a curvilinear to rectilinear latitude-longitude grid. I used the simple Ferret script in Appendix A Sec11 (see attached). I create two plots one before using the external function curv_to_rect (fig2.gif) and one after using the function (fig1.gif) (see the attached). The problem is the center of maximum and minimum in the figures 1, 2 are not the same. I'm feeling something wrong happened. My data is netcdf and the variables on polar stereographic (projection_params = "90.0 -32.0 0.933013"). and i = 51 ; j = 51 Another question, If I would like to draw my variable on index x=0:51 and y=0:51 for the polar stereographic projection and land map .. Who I can do that? Looking to your help!
