This site accesses daily weather station data for the period 1968 to the current year for 600 locations across Australia. This data is used to make calculations for the accumulation of winter chill and growing degree days/hours.
Because the chill and growing degree day calculations are based on weather data from the Long Paddock SILO, the calculations can only be updated when the weather data becomes available. The weather data from yesterday is usually available after about midday (AEST). The Long Paddock SILO uses data form the Bureau of Meteorology and patches this to create complete daily data sets. Stations that no longer record temperature data are synthetically in-filled with gridded data derived from statistical analysis.
All calculations are performed using the chillR package of Luedeling et al. (2013) & Luedeling (2017). The website has been developed by the QLD Government in conjunction with Hort Innovation.
