Hello everyone,
I want to plot smooth contour filled data with the given data. I have tried this code.
h1=contourf(X1,X2,DATA1,'edgecolor','none');
shading interp;
with this I am getting this plot. But I want a smooth plot. I would really appreciate your help. Thanks in advance.

The underlying problem might be the data you have in DATA1, if I simply do:
imagesc(DATA1)
and zoom in on the Kashmir(?) region it looks very peculiar, some kind of mixture between rasterized data and interpolated data on varying spatial resolution. The answer by Mathieu below looks nice to my eyes, if they are a suitable presentation of the data is for you to judge.

hello
with this FEx submission, you should be happy now
DATA2 = smooth2a(DATA1,10,10); % adapt the smoothing amount to your needs...
figure(2)
h2=contourf(X1,X2,DATA2,'edgecolor','none');
