Error analysis can be fun!!!

This page is a repository of information for planning the 3rd AMS Data Analysis Clinic Meeting, which will take place in Boulder in early 2011. A shorcut to this page is http://tinyurl.com/AMSClinic3

Dates and Location

The 3rd AMS Data Analysis Clinic Meeting will take place from Sun March 20 to Fri March 25 at the University of Colorado-Boulder. We'll start Sun @ 1 pm (after lunch). It will be organized by the Jimenez Group. We will post information here as it becomes available.

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 or 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 presentations and discussions will end on Thu @ 1 pm, and we will organize informal activities for Thu afternoon, and 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, name tags, hotel room block, etc.

Feedback from the past two Clinics is here and here.

Friday Activities

Hiking outside Boulder on Friday!

Note that CU and Boulder public schools have spring break this week, so the nearby outdoor recreation areas may be busy.

Snowshoeing

  • Last year we went to Eldora ski area's Nordic center, and we could do that again. Transportation is easy (bus from downtown Boulder, $5 each way). A trail pass is $15.
    • Snowshoe rental at Eldora is $20. (Or rent cheaper in Boulder, below.)
  • We could also go higher in the mountains to Rocky Mountain National Park, Brainard Lake, or Peaceful Valley (longer drives than Eldora, but usually fewer people). Depending on how many people want to go, we may need to arrange an extra vehicle. Ingrid has a park pass, so entrance for one vehicle is free at Rocky Mountain National Park.
    • Snowshoes can be rented in Boulder at
      • Crystal Ski Shop, 3216 Arapahoe Ave , Boulder, CO, (303) 449-7669, $12
      • REI, 1789 28th St, Boulder, CO 80301, (303) 583-9970, $15 with Ingrid's membership
