Workshop on the assessment of candidate models

(This first workshop took place on the 19th & 20th November 2012 at the Oakley Court Hotel, Windsor)

This initial workshop focused on identifying and prioritising the marine biogeochemical scientific questions that can feasibly be tackled by the next generation of Earth System Models. Second, it evaluated the candidate modelling approaches and their a priori strengths and limitations providing an assessment of their biological fidelity as well as their ability (or potential ability) to address a range of critical ESM questions. The outcomes of the workshop will feed into a report prepared by Prof Peter Cox (Exeter) which makes recommendations as to which model should be used.

The workshop opened with an overview of the network from Icarus Allen P1. This was followed by a presentation from Corinne le Quere UEAP2 on the scientific and policy challenges for earth systems modelling. Peter Cox P3 gave and overview of the challenges and requirements for selecting the ocean biogeochemistry model and Tom Anderson NOC P4 gave his perspective of the challenges for the next generation model. There followed a session whereby the candidate models were presented, highlighting their strengths, weaknesses and differences (Haddocc, Diat Haddocc Ian Toterdell UKMO P5, MEDUSA Andrew Yool NOC P6, ERSEM Icarus Allen PML P7, PLANKTOM 5/10 Erik Buitenhuis UEA P8. There followed a discussion on how well the current models represent these key processes from a conceptual and biological perspective P9. Finally there was a discussion of approaches to validating these processes, focussing on which aspects of the biological carbon pump and the availability of which observational data (BuitenhuisP10).
