Jeff and others,
I have a working solution and a non-working solution. I'm wondering
whether someone can help me understand the problems in the latter.
Please forgive in advance the long post, but all of my code is here.
First, you can get a dataset from :
Hello,
I'm trying to take a npstereographic grid of points and reproject it
so that I can save out a file in regular 0.5 degree lat lon grid
coordinates. The description of the grid points in the current
projection is here:

Jeff, thanks for the answer. Unfortunately I have a problem due to the
'polar' nature of the grid, the xin, yin values are not increasing. I
tried both passing lat and lon grids or flattened vectors of the
original data, but neither works. You can see my method here, which is
a new method of my
Apologies, I see I didn't need to change the xin, yin variables in the
interp function. I have it working now, but I still don't quite have
the plotting correct... be back with a report. -john

Closer, but still not quite right... not sure what I'm doing wrong??

John: Since I don't know what the plot should look like, it's hard to
say. Perhaps the data is just transposed? Let me back up a bit and
ask why you want to interpolate to a lat/lon
Jeff,
Thank you again for the quick response.
Unfortunately, I need to output the data onto a regular lat/lon 0.5
degree grid for including in another project (this is the format we
need, so I'll write the data out to a file).
For plotting, however, I would be interested in seeing the 'easy'
