GLO Future climate rainfall v01

Abstract

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This is GLO rainfall data including the period 1970 to 2102 in netCDF format. This dataset was used as climate forcing to drive surface and ground water modelling.

The seasonal scaling factors associated with CSIRO-Mk3.0 that are +4.5%, -2.1%, -4.5% and -2.8% for summer, autumn, winter and spring are used to generate trended climate inputs for the years 2013 to 2102. The trends assume global warming of 1-degree for the period 2013 to 2042, compared to 1983 to 2012. The global warming for 2043 to 2072 is assumed to be 1.5 degrees and the corresponding scaling factors for this period are therefore multiplied by 1.5. The global warming for 2073 to 2102 is assumed to be 2 degrees.

Dataset History

The future rainfall data were obtained using the historical rainfall multiplied by seasonal scaling factors.

The seasonal scaling factors associated with CSIRO-Mk3.0 that are +4.5%, -2.1%, -4.5% and -2.8% for summer, autumn, winter and spring are used to generate trended climate inputs for the years 2013 to 2102. The trends assume global warming of 1-degree for the period 2013 to 2042, compared to 1983 to 2012. The global warming for 2043 to 2072 is assumed to be 1.5 degrees and the corresponding scaling factors for this period are therefore multiplied by 1.5. The global warming for 2073 to 2102 is assumed to be 2 degrees.

The scaling factors are applied to scale the daily precipitation in the climate input series that is generated for 2013 to 2102 (Zhang et al., 2016).
