Uncertainty in ocean analysis methods and deficiencies the observing system are major obstacles for reliable reconstruction of past climate. The variety existing reanalyses is exploited a multi-reanalysis ensemble to improve state estimation gauge uncertainty levels. ensemble-based signal-to-noise ratio allows identification characteristics which robust (such as tropical mixed-layer-depth, upper heat content), where large exists (deep ocean, Southern Ocean, sea ice thickness, salinity),...
ACCESS-S1 will be the next version of Australian Bureau Meteorology's seasonal prediction system, due to become operational in early 2018. The multiweek and performance has been evaluated based on a 23-year hindcast set compared current POAMA. system considerable enhancements POAMA, including higher vertical horizontal resolution component models state-ofthe-art physics parameterisation schemes. is UK Met Office GloSea5-GC2 but ensemble generation strategy make it appropriate for multi-week...
ACCESS-S2 is a major upgrade to the Australian Bureau of Meteorology’s multi-week seasonal prediction system. It was made operational in October 2021, replacing ACCESS-S1. The focus addition new weakly coupled data assimilation system provide initial conditions for atmosphere, ocean, land and ice fields. model based on UK Met Office GloSea5-GC2 unchanged from ACCESS-S1, aside minor corrections enhancements. performance skill forecasts have been assessed compared There are improvements...
The real-time quality control (RTQC) methods applied to Argo profiling float data by the United Kingdom (UK) Met Office, States (US) Fleet Numerical Meteorology and Oceanography Centre, Australian Bureau of Coriolis Centre are compared contrasted. Data taken from period 2007 2011 inclusive RTQC performance is assessed with respect delayed-mode (DMQC). An intercomparison techniques performed using a common set profiles 2010 2011. systems found have similar power in identifying faulty but vary...
