<p class="MsoNormal"><span style="font-size:12.0pt;font-family:Monaco">We (the MIRA steering committee) would also like to try something new this time. After discussing Nick’s presentation, we would like to reserve 10-15 minutes for a roundtable discussion.
The theme of the discussion is <i><u>What is MIRA, and what can it do for me?</u></i> I will explain more at the beginning of the discussion, but our purpose is to get feedback from the community through a medium that is more personal than something like Google
forms. I am a little uncomfortable attempting a roundtable in a virtual format because there is no way for anyone to ‘read the room’ in such environments, but let’s give it a try and see how it goes!<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Helvetica Neue";color:black">Observations are considered the lifeblood of science: they are the closest we can come to knowing the truth. But are they fit for purpose? Each observation, whether
a satellite pixel or an in-situ measurement, only represents a small spatio-temporal domain. When using these observations we often implicitly assume they are representative of a much larger spatio-temporal domain. This is particularly the case when evaluating
global models but also occurs when comparing two observations (e.g. evaluation of a satellite product). The ‘errors’ introduced by this assumption can be substantial and are often comparable, if not larger, than measurement/retrieval uncertainties. I will
discuss attempts to estimate such representation errors, and discuss ways to reduce them.<o:p></o:p></span></p>
