Daily minimum for the Australian continent between 1970-2014. Daily minimum temperature regulates rates of plant growth and determines critical conditions such as the impact of frost on flowering and fruiting. Modelled by expressing each daily value as a difference anomaly with respect to the gridded 1976-2005 monthly mean daily minimum temperatures as provided by eMAST_ANUClimate_mmn_tmin_v1m0_1976_2005. The daily anomalies were interpolated by trivariate thin plate smoothing spline functions of longitude, latitude and vertically exaggerated elevation using ANUSPLIN Version 4.5. There was an average of 673 Bureau of Meteorology data points available for each day between 1970 and 2014. Automated quality assessment rejected on average 1.3 data values per day with extreme studentised residuals. These were commonly associated with days following missing observations. Cross validation residuals for all accepted data points had a mean absolute value of 1.14 degrees Celsius and a root mean square value of 1.53 degrees Celsius. A comprehensive assessment of the analysis and the factors contributing to the quality of the final interpolated daily minimum temperature grids is in preparation.
