<p class="MsoNormal"><a name="_GoBack"></a><span style="font-size:10pt;font-family:Arial,sans-serif">ECMWF assimilates observations from over 50
satellite instruments, and monitors many more in the operational system.
Recently the main focus has been in three broad areas:<br>
1) Full (or at least more complete) utilization of hyperspectral sounder
data; 2) Moving more moisture sensitive observations into the so called
"all-sky" assimilation framework, where we explicitly model the
impact of cloud and precipitation on the observations, and allow these
observations to influence the analysis; 3) An increasingly sophisticated
treatment of observation errors, notably for Atmospheric Motion Vectors
(AMVs), and observation error correlations for radiances. </span></p>
<p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif"> </span></p>
<p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif">In
the first area, ECMWF has been able to demonstrate that for cloud-free scenes
assimilation of IASI observations as radiances or Principal Components (PCs)
can give the same impact, and a better impact when more of the spectrum is
assimilated affordably through the PCs. Indeed, this advantage is sufficient
that the assimilation of cloud-free PCs is, in general, equal to and often
better than the assimilation of radiances in clear and overcast scenes, and
for channels peaking above cloud. In the second area, ECMWF has been
assimilating microwave imager data for many years through the all-sky route,
but now humidity sounders are also being moved to the all-sky framework, with
noticeable positive impact, especially on vector wind forecast scores. In the
third area, the impact of AMVs has notably increased through the use of scene
dependent errors, and experiments are showing not only can we cope with
observation error correlation, we may even be able to exploit it in a
positive way in some situations. In addition, the seminar will briefly
discuss the status of Radio Occultation assimilation, progress with data from
the Feng Yun satellites, new observation impact diagnostics, and a
perspective on current and future directions for data assimilation in general
at ECMWF.</span><span style="font-size:11pt;font-family:Arial,sans-serif"></span></p>
