| Project Abstract | Similar to the DROUGHT-AWAP-GRIDS, except that we use APMMA locations and Standardised Precipitation-Evapotranspiration Index (SPEI) rather than the Hutchinson Drought Index with AWAP Grid data. |

| Abstract | The dataset is focusing on drought assessment using APMMA locations and Standardised Precipitation Index (SPI) and Standardised Precipitation Evapotranspiration Index (SPEI), provides comprehensive data on drought indices and drought duration at APMMA monitor locations for the period of 2005 to 2019. This dataset includes SPI and SPEI indices, which capture deviations in precipitation and evapotranspiration from their long-term averages, respectively. |

| Abstract |
The data and methods are for the 2022 MJA-Lancet Countdown report. The drought method follows that outlined in Watts et al.12 We used the Standardised Precipitation-Evapotranspiration Index (SPEI) calculated on 6-month timescale. In this report we show that the SPEI can also be used to indicate extremely wet periods that may be associated with flooding (as it was in Eastern Australia during the first three months of 2022). Data We used monthly rainfall and temperatures, calculated using the Australian Water Availability Project (AWAP) gridded data January 1950 - March 2022 at 0.05 × 0.05 degree resolution.11 Methods This indicator represents the area impacted by excess drought events compared to the 1950-2005 baseline. The drought method follows that outlined in Watts et al.12 We used the Standardised Precipitation-Evapotranspiration Index (SPEI) calculated on 6-month timescale. Due to lack of wind speed data, the potential evapotranspiration (PET) was calculated using the Thornthwaite method rather than the FAO-56 Penman-Monteith method. We used the algorithm provided in the R package “SPEI” (Santiago Beguería and Sergio M. Vicente-Serrano (2017). SPEI: Calculation of the Standardised Precipitation-Evapotranspiration Index. R package version 1.7. The SPEI is a multiscalar index, which takes into account both precipitation (using the basis of the more commonly used SPI index) and temperature, to estimate potential evapotranspiration. More information on this index and its calculation can be found here: https://CRAN.R-project.org/package=SPEI. |
