Sen Gupta (NPLI) A call for paper has been circulated to the community (APMP TCTF members and URSI GASS 2011 Session Conveners) and two papers have been submitted. 6 more papers are expected. 2) Maintenance of member list on the APMP website New APMP website has a function to update member list by the TCTF chair (not by APMP secretariat like before). Please send removal, correction, and modification request to TCTF chair. A new member application can be sent to the TCTF chair from the website. The new member is added to the list upon approval by TCTF chair. It is safer to notify the TCTF chair by , too.

Matters to be discussed Promotion of R&D Activities in the TCTF Community Possible Technical Supports for Developing Economies Actions for Future Meetings New Structure of the TCTF Guidelines for Uncertainty Evaluations in CMC Tables
