AMS Clinic2

This page is a repository of information for planning the 2nd AMS Data Analysis Clinic Meeting in Boulder. A shorcut to this page is http://tinyurl.com/AMSClinic2/

IMPORTANT: Please RSVP (names, affiliations, snow day info, etc.) on this (open) google doc so we can plan food and schedule accordingly

General Information and Location

The results of the feedback survey for the meeting are here.

The people who should attend this clinic are those who are directly doing (or are VERY involved in directly supervising) AMS data analysis of field of lab data. The clinic will be much less useful for PIs who are not directly involved in data analysis, or for people who are just starting to learn about the AMS but haven't done serious data analysis yet.

The dates will be Mon Feb 22 to Thu Feb 25. We'll start Mon @ 9 am, so people should fly in the evening before (Doug and Manjula promised to fly in the night before too). We plan to end on Thu @ 5 pm, and we will organize skiing, snowshoeing and other activities on Friday for people who can stay an extra day, so please plan your flights accordingly. As planned, this is "out of phase" with the AMS Users Meeting and the heavy Fall meeting season (AAAR, EAC, AMS Users Meeting, AGU...).

There is no registration fee, but please let us know if you are coming to plan food, coffee, tables, power, internet, etc.

Program

The structure of the 2nd Clinic is 4 days, not just focusing on high-resolution, but rather on:

• day 1: UMR issues, SQ, CE, RIE, spectra comparisons...
• day 2: PMF
• days 3 & 4: HR issues, elemental analysis, HR-PMF + errors etc.

The content will be determined by the interests of the participants, and the schedule can be adapted as needed.

Day 5 Play in Colorado

• For those wishing to extend their trip to ski, snowshoe, or enjoy some outdoor activities, some CU folks can help plan something fun.

Lodging

• We have reserved a block of 20 rooms for Sunday February 21, 2010 through Friday February 26, 2010. At the Millenium hotel in Boulder. (Address is 1345 Twenty-Eighth Street) Boulder, CO 80302).
• The group rate for a double bedded room is $109.00 per day.
• Reservations can be made by calling 303.998.2480 or 1.800.545.6285 and refer to the AMS Users meeting or confirmation code 1002UNIVCU
• Reservations can also be made online here and receive the same group rate.
• The group rate is offered 3 days prior and 3 days after the room block that is reserved until the hotel reaches an occupancy of 80% so if you plan on staying after the clinic has finished making an early reservation may be beneficial.

  • Update how to visit our group: Post google maps and PDF with directions (link the one from last year). How to get back to the aiport. (Will print copies for start of meeting) (Amber)
  • Name tags (printed ahead of time)
  • Find out about clickers: Ingrid will find out (CHEM, Athletic Center via Michael, Campus via Donna)

• Clinic itself
  • rotating and helping users

• To do
  • Jose to revisit emails about molecules to analyze
  • Once settled on button export for spectral database, ask James to do the same in Q-AMS software
  • Ingrid will ping people about discussing their PMF cases
  • Donna will ping ions list folk
  • Jose will ping database folk + create master volunteering Wiki
  • Ask Eben to give short stand-up on life with and without an AMS (10 min)
