DEM - Differential Emission Measure - Part 2

Leaders: Mark Weber and Paul Boerner

Thermal studies with AIA

This is the second of two sessions on using AIA data for thermal (especially DEM) analysis. In this session, we will focus on the application of DEMs or related thermal data products from AIA. In particular, we will focus on two questions:

How can DEMs be used to gain a deeper understanding of the physics of the solar atmosphere? How do they interface with physical models of coronal structures?
Should there be an "automated DEM data product" that continuously produces thermal maps or shorthand DEMs at some substantial fraction of the AIA cadence and resolution? If so, what should that automatic DEM data product look like? What would it be used for?

Brief Talks

Markus Aschwanden (~10 minutes + discussion): forward-modeling of theoretical DEMs (based on hydrodynamic evolutions of heating and cooling processes) to observations
Mark Weber/Paul Boerner (~20 minutes + discussion): the Automated DEM data product; responses to a survey of potential end-users, and presentation of a strawman data product concept

Discussion Topics

In addition to the discussion of the specific issues raised in the talk, we will cover the broader issues of how DEMs can be used to do science, and how DEM-related thermal data products can be used to enhance the value of the AIA data.
