GrainGrowers has implemented the internationally peer reviewed Food and Agriculture Organization of the United Nations (FAO) Combined Drought Index for Australia, known as the Australian Drought Monitor. This is the first drought model developed in Australia at 1km resolution, providing ProductionWise subscribers high resolution drought status information at farm level. This is now available to all ProductionWise subscribers through the new Drought Monitor page.
Utilising GrainGrowers extensive national archive of high resolution spatial grids consisting of rainfall, temperature and normalised difference vegetation index (NDVI) data, the drought monitor is derived through the statistical comparison of how the present conditions (inclusive of the last 3 months) deviate from the multi-year long-term average for the same time period.
National images of the Australian Drought Monitor are produced every 10 days and are freely available from the GrainGrowers website.
