Motivation and Format of the Clinic

The Clinic is a HANDS-ON discussion-based workshop. The people who should attend the AMS Clinic are those who are directly using the AMS and 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 directly using the instrument and doing data analysis, or for people who are just starting to learn about the AMS but haven't done serious instrument use and data analysis yet. Attendees are expected to bring to the Clinic datasets in which they are currently working, and be ready to use them as a basis for discussion with the group.

Dates and Location

The 5th AMS Instrument and Data Analysis Clinic and 2nd Aerodyne CIMS Meeting and Clinic will take place in the Spring of 2013 at the University of Colorado-Boulder. They are organized by the Jimenez Group and Aerodyne, and also sponsored by CIRES.

Details of 5th AMS Clinic

  • 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 register if you are coming to plan food, coffee, tables, power, internet, name tags, hotel room block, etc.
  • Feedback from past Clinics has been very positive overall, and we try to learn every time how to make the Clinic more useful and interesting to the users. You you can see the details for 2009, 2010, and 2011, and 2012.
