	<abstract content_type="html">We have used high spectral resolution spectroscopic measurements from the MIPAS instrument on the Envisat satellite to simultaneously retrieve
vertical profiles of H&lt;sub&gt;2&lt;/sub&gt;O and HDO in the stratosphere and uppermost troposphere. A thorough error analysis of the retrievals confirms
that reliable &amp;delta;D data can be obtained up to an altitude of ~45 km. Averaging over multiple orbits and thus over longitudes further
reduces the random part of the error. The absolute total error of averaged &amp;delta;D is between 36 &amp;permil; and 111&amp;permil;. With values
lower than 42 &amp;permil; the total random error is significantly smaller than the natural variability of &amp;delta;D. The data compare well with
previous investigations. The MIPAS measurements now provide a unique global data set of high-quality &amp;delta;D data that will provide novel
insight into the stratospheric water cycle.</abstract>
