NOC simulations
Completed
• ORCA-100, NEMO v3.2, reanalysis, 1966-2006
– Utilised in Yool et al. (2011)
• ORCA-025, NEMO v3.2, reanalysis, 1988-2008
– Based on Popova et al. (2010)
• ORCA-100, NEMO v3.2, HadGEM2-ES, 1860-2099
– Utilised in Yool et al. (2013)
• ORCA-025, NEMO v3.5, HadGEM2-ES, 1980-2099
– Based on Yool et al. (2013)
Future forecast
• HadGEM2-ES forcing
• Initialised at 1860 (high-resolution spun-off of low-resolution at 1980)
• RCP8.5 scenario (strong warming and ocean acidification)
