Namoi mean annual rainfall time series prediction

Abstract

This dataset was derived by the Bioregional Assessment Programme from a source dataset. The source dataset is 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

The data contains mean annual rainfall for whole of Namoi subregion from 1900 to 2012. The last 30 years of data (1983 to 2012) is used to project rainfall data for three 30-year blocks starting from 2013 to 2102 using rainfall scaling factors.

Purpose

The data is used in the AWRA-L/R model to project future runoff under baseline and coal resource development pathway.

The data is also used to plot time series of observed (1900 to 2012) and projected (2013 to 2102) annual precipitation averaged over the Namoi subregion using the script climate.m that takes input extends to three 30-year periods with scaling factors. bsmooth.m returns weighted smoothing of vector [x] over a window of length lwin = 23 years. The resulting plot is shown in NAM261 report.

Dataset History

This resource was created using BAWAP data. This source data was is the Bureau of Meteorology rainfall grids. The annual data were generated from daily data.
