Indian Ocean Climate Initiative Stage 3 (IOCI3) - Downscaled Climate Projections for Western Australia
IOCI3, a climate research collaboration between CSIRO, BoM and the Government of Western Australia produced statistically downscaled projections for daily rainfall and maximum and minimum temperature for south-west WA (29 sites) and north-west WA (9 Kimberley sites and 10 Pilbara sites). These fine-scale projections for mid-century and end-of-centu... morery time periods are useful for climate change adaptation management and planning (but see caveats & limitations under "Lineage" and "Read me" files). These results are provided as CSV (comma-separated-values) files. less

These statistically downscaled rainfall simulations were produced using atmospheric predictors extracted from the historically based record using NCEP/NCAR reanalysis (NNR; 1959-2009) and five global circulation models (GCMs) for the SRES B1 (low), A1B (medium) and A2 (high) greenhouse gas emissions scenarios for baseline (1962-1999); mid-century (2047-2064) and end-of-century (2082-2099) time periods. Statistically downscaled temperature projections were produced from dynamically downscaled projections using the same GCMs and for the same periods but only under the SRES A2 (high) emission scenario. The NNR and GCM predictors were used to drive Non-homogeneous Hidden Markov Models (NHMMs) that were calibrated to networks of stations in south-west and north-west WA. The NHMM is a stochastic technique that can generate multiple realisations of rainfall and temperature. The application of these techniques was advanced under IOCI3 and applied to the tropics for the first time.

CLSD IOCI3 Theme 3 - C2006/4983
Project 3.1 of IOC3 sought to produce fine-scale projections of future rainfall and temperature for south-west Western Australia using statistical downscaling, for use in climate change impact and vulnerability assessments. Project 2.3 of IOCI3 developed the application of these statistical downscaling methods for the tropics, to provide fine-scale... more projections of future rainfall and temperature for north-west Western Australia for use in climate change impact and vulnerability assessments. less
Indian Ocean Climate Initiative Stage 3 (IOCI3)
The Indian Ocean Climate Initiative Stage 3 (IOCI3), a climate research collaboration between CSIRO, BoM and the Government of Western Australia, has produced climate projections for south-west and north-west WA. These include fine-scale (statistically downscaled) projections for rainfall and temperature (IOCI3 Projects 2.3 and 3.1); projections of... more extreme rainfall, including rainfall contributions from tropical cyclones; and projections of hot spells (heat waves) (IOCI3 Projects 2.4 and 3.2). less
