Abstract / Summary:
Preface
One of the goals of the Climate Variability Program in the Cooperative Research Centre (CRC) for Catchment Hydrology is to develop and test computer programs for generating stochastic climate data at time scales from less than one hour to one year and for point sites to large catchments. The appropriate models will be part of SCL (Stochastic Climate Library - a suite of stochastic climate data generation models), a product in the CRC for Catchment Hydrology's Modelling Toolkit (see www.toolkit.net.au/scl).
This report describes the development and testing of a multi-site daily rainfall model (multi-site two-part model nested in a monthly and annual model). The model can be used to generate stochastic daily rainfall data for many sites (or catchments) that preserve the statistical characteristics at each site as well as the rainfall correlations between sites. The stochastic daily rainfall data can then be used to drive hydrological and system models to quantify the uncertainty in environmental systems associated with hydroclimatic variability. The two-part model is a model in SCL.
