Introduction

Data management and curration of Palæoclimate dataproduced by BRIDGE research group

In collaboration with University of Bath (UKOLN), Universityof Leeds (Earth Science) & University of Southampton(Archæology)

Data centered around climate model runs and outputs fromHPC facilities (institutional and national)

This includes model’s binaries, initial conditions, forcings,model outputs, graphical analysis

Very diverse user base, not only palæoclimate researchers, butgeologists, biologists, archæologists, media,. . .

Methodology

Pre-existing infrastructure

Knowledge of existing code

Day-to-day maintenance and evolution of user needs

User interviews (informal, using users’ support requests)

User survey (still on-going) using modified DAF to includeexternal users

Stakeholder Analysis

Worked jointly with HPC group with University wide storageproject

Devided users into roles (Swann, 2008)

Task Based Analysis

Role based model did not fit with reality

Users have more than one role

Interactions between roles and users can be complex

Tasks analysis approach more appropriate (Based on Treloar,ANDS, 2009)
