CABLE as a key component in ACCESS: present status and the future

DESCRIPTION

This presentation by Ying-Ping Wang from CSIRO Oceans and Atmosphere explores the role of CABLE as a critical component of the ACCESS system. It provides an overview of CABLE's integration into ACCESS1.4 and its evaluation against JULES, with ongoing implementation into ACCESS 2.0. Notably, CABLE has garnered interest from 109 users across 65 institutions in 14 countries, contributing to significant scientific outputs. Key areas of focus include land use change, carbon feedback mechanisms, and innovative modeling approaches. Future directions involve benchmarking and harnessing field observations for enhanced performance in climate modeling.

  1. CABLE as a key component in ACCESS: present status and the future Ying-Ping Wang CSIRO Oceans and Atmosphere

  2. CABLE: present status and its users • CABLE are managed through SVN repository; • CABLE has successfully implemented into ACCESS1.4 and evaluated against JULES, and is being implemented into ACCESS 2.0, and also into JULES framework; • Since 2013, we have 109 users outside CSIRO from 65 other institutions in 14 countries (including 40 students from 6 other countries). In 2017, 5 high impact papers published, and 4 more under review.

  3. Increasing CABLE-related journal papers

  4. Futures (1 to 2 years) • New science • Land use change • Biological N fixation • Benchmarking • the first protocol • JULES/CABLE comparison • Applications • Effects of land use change on carbon-concentration feedback • Nonlinear carbon-climate feedbacks in ACCESS • ……..more

  5. Benchmarking Poor Poor

  6. Future (long term> 2 years) • Key science development guided by benchmarking and significant science and policy issues • Trait-based global land modelling • climatic consequence of human activities • interactions with surface air chemistry • Forecasting • Better methods for using wide range field observations to improve CABLE • Surrogate modelling and ensemble simulations • Using models to test observation-based hypotheses.

  7. Attribution (Zhu et al. 2016 and Zeng et al. 2017, NCC) Warmer Greener Overall greening slowed down surface warming by 0.09±0.02oC since 1982, or 12% over last 3 decades.
