Total_and_Bushfire_specific_PM25_Aus_2001_2020_v1_3

Brief description

This dataset contains daily total PM2.5 predictions for Australia from 2001 to 2020 based on a random forest model. A decomposition of total PM2.5 to allow for estimation of bushfire-specific PM2.5 is also included. This is version 1.3 of the CAR Bushfire Smoke Exposure project, superseding v1.2. A Seasonal-Trend decomposition using LOESS (STL) decomposition was calculated for years 2001-2019, using a seasonal window of 45. Due to the abnormal levels of PM2.5 in January 2020 from severe bushfires, the year 2020 was not included in the STL calculation. However, the decomposition was extrapolated to 2020 using 2019 seasonal and trend values. Flags for classifying days of high PM2.5 (e.g. dust event, bushfire event) were taken from v1.2. As the v1.2 prediction grid was slightly smaller than that of v1.3, an extrapolation was performed on the flags to cover coastal pixels. The creator acknowledges the Sydney Informatics Hub and the University of Sydney’s high performance computing cluster Artemis for providing the high performance computing resources that have contributed to the production of this dataset. This research was undertaken with the assistance of resources from the Clean Air and health Research Data and Analysis Technology platform (CARDAT), which is supported by funds from The Centre for Safe Air (CSA; https://safeair.org.au/), which is funded by the National Health and Medical Research Council (2015584), the Curtin WHO Collaborating Centre for Climate Change and Health Impact Assessment, and the Australian Research Data Commons (ARDC) AirHealth Data Bridges project (https://doi.org/10.47486/PS022). The Bushfire Smoke Exposure project received seed funding project support from the CSA, as well as the ARDC Bushfire Data Challenges project (https://ardc.edu.au/project/assessing-the-impact-of-bushfire-smoke-on-health/) and the Australian National Health and Medical Research Council (APP2004514) Ideas Grant - Bushfire smoke exposure during pregnancy and epigenetic changes in offspring (https://www.nhmrc.gov.au/funding/find-funding/ideas-grants).
