# GRACE (Gravity Recovery and Climate Experiment)

I'd like to start a page on the GRACE experiment, data of which are already mentioned on Sea level rise. So far I've only got this link so I won't create the page yet.

Ok, I've found some material, and there's a short page now. I hope the capitals are OK, see the reference.

Ah, by the way, there's "attitude sensors" and I think it should be "altitude sensors". Unless somebody knows what an "attitude sensor" could be, I'll change it.

I don't which is meant, but the "attitude" of an engineering object is its "orientation" (eg, pointing at 20 degrees, in the westward direction, to the vertical) and attitude sensors do exist that measure that.

@David, thanks! I didn't know. I suppose the GPS instruments already measure the altitude.
