APPENDIX B: Workshop Agenda

VAMOS/PACS Workshop on Field Programmes - CLIVAR VAMOS Panel 1st Session

Monday, March 30, 1998:

The goal for the first day is to provide a review of the science objectives related to the Variability of the American monsoon systems and then work toward a consensus on the objectives, questions, and hypotheses that VAMOS Field Programmes should address. Each talk should end with a summary list of scientific objectives and questions that will form the basis for the development during the rest of the meeting of field programmes.

Morning:

Tuesday, March 31, 1998:

Morning:

The goals for the morning are to identify what relevant field work has already begun or been planned and to begin to establish focal points for VAMOS field programmes. Review of field work in progress and or planned, both as part of VAMOS and as part of related programmes that will add to, support or provide the context for VAMOS field programs. me. These are meant to be overviews, providing summaries of science objectives, summary time lines.
