Bias in dynamically downscaled rainfall characteristics for hydroclimatic projections

Nicholas J. Potter et al.

Data sets

High resolution daily rainfall gridded datasets from 1900 onwards Bureau of Meteorology http://www.bom.gov.au/climate/austmaps/metadata-daily-rainfall.shtml

NSW Climate Data Portal Office of Environment and Heritage https://climatedata.environment.nsw.gov.au/

Short summary
There is a growing need for information about possible changes to water resource availability in the future due to climate change. Large-scale outputs from global climate models need to be translated to finer-resolution spatial scales before hydrological modelling. Biases in this downscaled data often need to be corrected. We show that usual bias correction methods can retain residual biases in multi-day occurrences of rainfall, which can result in biases in modelled runoff.
