This rainfall analysis tool was developed as part of the GRDC South "Using Seasonal Forecasts" extension project (April 2018 - Feb 2020). See more about the project here: https://forecasts4profit.com.au/About

This tool aims to show longer term rainfall records for selected locations where longer term record exist. It also seeks to show how the climate drivers such as El Niño-Southern Oscillation and Indian Ocean Dipole have influenced seasonal rainfall in the past.

The rainfall data dating back to 1900 are interpolated values from the Queensland Government's Department of Environment and Science SILO database. For more information please see SILO climate data. https://legacy.longpaddock.qld.gov.au/silo/index.html

The classification of ENSO and IOD years comes from: 

• Bureau of Meteorology classifications for ENSO years Australian rainfall patterns during El Niño and La Niña events, http://www.bom.gov.au/climate/enso/ensorain.comp.shtml
• BoM classifications for Indian Ocean Dipole events post 1960 and the classifications of Meyers et al 2007 (https://journals.ametsoc.org/doi/full/10.1175/JCLI4152.1) The Years of El Niño, La Niña, and Interactions with the Tropical Indian Ocean, and
• modified by Ummenhofer et al 2011 pre 1960 What causes southeast Australia's worst droughts? https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2008GL036801

Graph design concepts were provided by Peter Hayman, Dale Grey, Darren Ray, Graeme Anderson & CeRDI.
