Draft agenda for HMI Team Meeting in January 2005


As of 3 PM, 24 Jan.


NOTE – this is still in development – MOST BUT NOT ALL SPEAKERS HAVE AGREED


This is NOT a science meeting where we get to learn of the latest neat results.  It is a planning meeting where we can discuss the implementation plan for preparing to have neat results in the summer of 2008!


We will be able to accomplish the meeting goals in 2 days. So we have scheduled Weds and Thursday 26 and 27 January for the meeting.  This choice allows those with teaching conflicts on Weds to attend the in depth discussions on Thursday and does not force a meeting ending after 5 PM on a Friday night.


The draft agenda is as follows:


A. HMI Development Overview, Weds 26 Jan - CISX-101,  9:00-12:00


Overview of status of HMI development

·      Phil Scherrer - Investigation status and goals of this meeting

·      Dean Pesnell - almost SDO Project Scientist - Status of SDO and LWS

·      Barbara Fischer - LMSAL HMI Deputy Project Manager -  Instrument development status

·      Jesper Schou - Instrument estimated performance

·      Rock Bush - Operations Concept

·      Phil Scherrer - JSOC overview

·      Jim Aloise - JSOC implementation

·      Rasmus Larsen - Processing overview, user view of pipeline


B. HMI Science Goal Development, Weds 26 Jan - CISX-101, 1:00-5:00


Science goals overview as intro to discussions/overviews by lead speakers for the science goals, needed development, processing needs, products.  These discussions are about what is presently planned.


·      Phil Scherrer - HMI Science Plan Overview

·      Tom Duvall – time distance *

·      Doug Braun - holography *

·      Rick Bogart –rings & synoptic interior *

·      Jesper Schou - global HS *

·      Nagi Mansour -Modeling and Simulation *

·      Junwei Zhao -Intercomparison & Validation *

·      Steve Tomczyk - vector field measurements and reconstruction *

·      Yang Liu - MHD and space weather products *

·      Rock Bush – feature recog, limb shape, and TSI issues

·      Phil Scherrer - forecast products

·      Sasha Kosovichev - Interior – Heliosphere links

·      Rasmus Larsen - needs from working groups to define pipeline processing

* detailed discussion with more inputs on Thursday.  The topics are here to let “the other half” of HMI know what is planned and to provoke discussion among the specialists on Thursday.


C. HMI Working Group Meetings,

Thurs 27 Jan - CISX101 and HEPL Conf rooms


Parallel discussion sections.  These sessions are where we want real input from the team concerning what data products should be produced in the pipeline, what needs to be accomplished to enable progress on the science goals, e.g. analysis methods, simulations, model developments, hare&hounds exercises, etc. There will be two parallel sessions.  Please note that the following agendas are viewed ad being flexible and may have additions arising from discussions on Wednesday.  The topics are:

Magnetic Fields, etc.  HEPL Conference Room


Chair – Yang Liu, Todd Hoeksema


Discussion of the requirements for data reduction and data analysis of the magnetic field will be organized around several topics.  The purpose of the sessions is to understand the requirements on the measurements and the data analysis algorithms for the vector magnetic and photospheric flow fields, and the computing needs for modeling, analysis, and the synoptic and forecasting efforts.  In the morning sessions we will address the two data reduction issues.  In the afternoon topics will focus on data analysis.  Each session will include time for presentations and time for general discussion.

We will have a chairperson and note-taker for each of these discussions.  The idea is to explore in more detail the data products that need to flow out of the pipeline processing as well as the science analysis development that needs to take place in order to use these products.


There will be an attached LoHCo helioseismology meeting on Tuesday the 26th in the HEPL conference room.

The agenda for that meeting is at  http://gong.nso.edu/science/meetings/lohco/


The meeting will start in CISX 101, a conf room in the NE corner of the Center for Integrated Systems building

Just down the street from our offices.
