Overview


1.Project Overview

• Project Kick Off - 1st April 2015

• Started as Phase 2 CCI project

• Builds on Phase 1 achievements of Greenland Ice Sheet CCI project

• User and product requirements for Antarctic CCI project

determined by 4 month scoping study in 2014

• Algorithms and systems ported from Greenland CCI Phase 1


2. User Requirements

• User survey widely advertised on social media and CryoList

• 164 respondents

• Median expertise >10 years and wide range of disciplines

• Focus product generation on ice sheet margins
