Water Modelling-Palaeo Stochastic Climate Data-Greater Sydney

Overview

This stochastic climate dataset relates to the Greater Sydney region. It supports hydrological assessment and regional water planning across the Greater Sydney area.

The stochastic data are 10,000-year daily datasets of rainfall and potential evapotranspiration generated using observed datasets combined with palaeo-climatic data. This work has been undertaken by researchers at the University of Adelaide and the University of Newcastle and has been used in Regional Water Strategies.

This dataset is made available as open data to support transparency, research, planning and informed decision-making by all interested users.

Dataset Contents

Climate data are supplied as individual ZIP files, each clearly labelled by Station ID and climate variable. When accessed through the WaterInfo web portal, the file description identifies the station name and confirms inclusion of metadata and quality assurance documents.

Each ZIP file contains:

1. A .csv file of daily climate data covering 10,000 years (format: date, data; filename begins with the Station ID);
2. A metadata PDF describing the geographic location of the climate station, data type, period of observed data used for generating stochastic data, and a location map; and
3. A quality assurance PDF.

The climate variables include one or more of the following: rainfall, evapotranspiration (Mwet: Morton’s wet area potential evapotranspiration, Mlake: Morton’s lake evaporation, Mpot: Morton’s point potential evapotranspiration, Penman-Monteith reference evapotranspiration (FAO56)), Maximum temperature, Minimum temperature.

Within each ZIP file name, the number shown (for example, 59093_Rain.zip) represents the Station ID Number (for example, Station 59093), while the suffix (such as Rain, Mwet, Mlake, Mpot or FAO56) identifies the climate variable contained in the file.
