Brief description
This collection consists of application-ready climate projections based on observations, adjusted through a quantile-delta-change method to incorporate projected climate changes from CMIP6 Global Climate Models.The collection consists of daily projections of precipitation, mean downwelling shortwave radiation, maximum and minimum near-surface temperature, maximum, mean and minimum near-surface relative humidity, and mean near-surface wind speed for 9 CMIP6 models. Two 30-year windows of projections are available (2035-2064 and 2070-2099) for four shared socio-economic pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5). Data is based on BARRA-R2 historic climate variability for Australia. This dataset is on the original 11km BARRA-R2 resolution.
In addition, historical baseline data for 1985-2014 from BARRA-R2 used for the quantile-delta-change adjustment are also available in the collection.
More in-depth information on the dataset can be found in the technical report: https://doi.org/10.25919/03by-9y62
This collection is not updated frequently.
Lineage: Daily data from 9 CMIP6 models (ACCESS-CM2, ACCESS-ESM1-5, CESM2, CMCC-ESM2, CNRM-ESM2-1, EC-Earth3, MPI-ESM1-2-HR, NorESM2-MM, UKESM1-0-LL) are used to calculate climate changes between a 1985-2014 baseline period and the two future projection periods for each SSP. The projected changes are then applied to 1985-2014 baseline data from BARRA-R2 to produce the application-ready datasets. The quantile-delta-change method is used, which applies different climate changes to different parts (quantiles) of the distribution of daily data.
This process is done using python software available at https://github.com/AusClimateService/qq-workflows/tree/main/qdc-cmip6.
More in-depth information on the method can be found in the technical report: https://doi.org/10.25919/03by-9y62
The application-ready projections have also been subject to a quality-control and assurance check utilising a python script (https://github.com/climate-innovation-hub/qdc-cmip6-qaqc) to ensure full data coverage and compliance with metadata standards, with the process documented in the QAQC report: https://doi.org/10.25919%2F4n26-fh08
