distort the major land masses too much, unless you live in Greenland. But
for data? Never. What's more, the gridded raster supplied didn't even mask
out the lobed shape of the IGH projection, so even as a "pretty picture"
you would have an incorrect idea of where the oceans were.

If I'd needed this data I would have really tried to contact the creators
and get it in a better form - especially since transforming to lat-long is
going to require interpolation and my method had a small element of
guesswork in it too.
