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:

1. Spatial Resolution: 0.05° X 0.05°
2. Temporal Resolution: Daily  
3. Date Range: 1st January 1851 to 31st December 2014
4. Source Data: 20th Century Version 2c
5. Ensembles used: 5, 7, 15, 17, 19, 20, 23, 24, 34, 37, 38, 43, 55  
6. 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
7. Bias Correction method used: Quantile-Quantile (QQ) matching using Monotone Piecewise Hermite Cubic Spline
8. Interpolation technique used to resample 20CRv2c: Biliniear
9. Fill Value: -9999
10. Areas masked with fill value:
    • Ocean region outside Australia
    • Outlier values below the lower limit
    • Outlier values above the upper limit 
11. Datatype: float32
