Bias-Corrected and Interpolated 20th Century Reanalysis Version 2c (20CRV2c) dataset for Australia

This bias-corrected century dataset contains daily maximum temperature, rainfall, relative humidity, and wind speed data at a spatial resolution of 0.05 degrees by 0.05 degrees, conveniently packaged into yearly files from 1851 to 2014. Further details about the dataset are listed as follows: Spatial Resolution: 0.05° X 0.05° Temporal Resolution: Daily Date Range: 1st January 1851 to 31st December 2014 Source Data: 20th Century Version 2c Ensembles used: 5, 7, 15, 17, 19, 20, 23, 24, 34, 37, 38, 43, 55 Source Data which was considered ground truth for the bias correction: Australian Water Availability Project (AWAP) gridded dataset for temperature, rainfall and relative humidity NCEP-NCAR Renalysis for Wind Speed Bias Correction method used: Quantile-Quantile (QQ) matching using Monotone Piecewise Hermite Cubic Spline Interpolation technique used to resample 20CRv2c: Biliniear Fill Value: -9999 Areas masked with fill value: Ocean region outside Australia Outlier values below the lower limit Outlier values above the upper limit Datatype: float32 Variable Unit Lower Limit Upper Limit Filename Temperature C -50 C 100 C tmax_{year}.nc Rainfall mm 0 mm 1000 mm prate_{year}.nc Relative Humidity % 0 % 100 % rh_{year}.nc Wind Speed km/hr 0 km/hr 500 km/hr ws_{year}.nc Biswas S, Chand SS, Dowdy AJ, Wright W, Foale C, Zhao X, Deo A (2022) Statistical Calibration of Long-Term Reanalysis Data for Australian Fire Weather Conditions.
