WORK PLAN OF THE CIMO EXPERT TEAM ON DEVELOPMENTS IN IN-SITU TECHNOLOGIES (ET-DIST)

1. INTRODUCTION

The proposed Work Plan for ET-DIST is contained in the Appendix for the consideration and approval of the CIMO Management Group. It will be noted that responsible persons have not yet been identified for Tasks 4 (radiation), 9 (polar observations) or 10 (soil moisture). The current membership of the ET-DIST may lack the required expertize for these tasks and the session is invited to consider options for filling these gaps.
