Application-ready quantile-delta-change (QDC) scaled CMIP6 climate projections for Australia (global warming levels, 5km grid)

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. Up to four 20-year windows of projections are available per model, corresponding to global warming levels of 1.5°C, 2°C, 3°C, and 4°C above pre-industrial (1850-1900) derived from simulations of the SSP3-7.0 shared socio-economic pathway. Data is available with two sources of historic climate observations for Australia: AGCD (for precipitation and temperature only) and BARRA-R2. The BARRA-R2 baseline data has been interpolated to the same resolution as AGCD (~5km).

Historical baseline data from AGCD and BARRA-R2 used for the quantile-delta-change adjustment are also available.

This collection is not updated frequently.
