Growing Degree Day Daily Accumulation Maps

A statewide grid surface (80m spatial resolution) delineating Degree Day accumulation across the state of Tasmania is produced daily for the Tasmanian growing season (i.e. between months October through to April). The outputs are dynamic with the map products updated daily. Three map products are produced: 1) Growing Degree Day Heat Accumulation Tracker - Current Season: GDD accumulation to date (refer to link below) for the current growing season (updated daily) 2) Growing Degree Day Heat Accumulation Tracker - 10 year average: GDD accumulation to date (refer to link below) based on the 10 year average (i.e. averaged GDD units garnered from data 10 years prior to the current growing season; updated daily) 3) Growing Degree Day Anomaly - Current season vs 10 year average: The difference between 1) and 2) where negative values indicate that the current growing season is cooler relative to the 10 year average, positive values indicate a warmer season. Map outputs are based on daily records produced from 43 Bureau of Meteorology (BoM) Automatic Weather Station sites with further bias correction provided by 267 independent air temperature logger recording sites (courtesy of the Tasmanian Government Department of Primary Industries, Parks, Water and Environment (DPIPWE)). For operational real-time application, the mapping was fully automated in the R programming language and hosted on a cloud-based computing platform courtesy of Sense-T and hosted on the high performance computing cluster provided by the Tasmanian Partnership of Advanced Computing (TPAC) of the University of Tasmania.
