We ask two questions:
1) How well are remotely-sensed heliospheric structures depicted, and how can their time histories and topologies be confirmed?
Where necessary I will add comments
2) How well are in-situ measurements observed and extrapolated to remote-observations, and what do they tell us about plasma time histories and structure topologies?

2. Remotely Sensed Observations
Session 16 -The time histories and topologies of heliospheric structures measured in-situ
Remotely Sensed Observations
How do you know the speeds of these structures,
and when do you expect they will reach Earth?

3. So, provide a model to depict solar wind time histories and shapes

MHD Modeling Efforts
So, provide a model to depict
solar wind time histories and shapes

4. Session 16 -The time histories and topologies of heliospheric structures measured in-situ
In-situ Measurements
You can measure structures in situ, but how do you know their 3-D shapes, and whether these are what you observe remotely?
One way is to test different models for agreement with in-situ results.

5. Session 16 -The time histories and topologies of heliospheric structures measured in-situ
In-situ Measurements
So measure these structures, determine how accurate these measurements are, and use the knowledge of the passing column in an attempt to extend beyond the spacecraft bounds.
