iHVI: AN OPEN-SOURCE TOOLKIT FOR CONSTRUCTING INTEGRATED HEAT VULNERABILITY INDEX IN AUSTRALIA

This work presents a comprehensive Global Navigation Satellite Systems (GNSS) climate dataset, covering up to 22 years and over 5085 globaly-distributed stations. The data enables the monitoring of atmospheric humidity and circulation, which is crucial for understanding the mechanisms of climate change and climate extremes. Through rigorous quality control, assessment and comparison with trusted sources, the dataset supports better weather forecasting, climate monitoring, and risk assessment.

A case study assessing drought risk in Papua New Guinea (PNG) provinces for retrospective years (2014–2020) was conducted to demonstrate the development and validate the application of a tailored and semi-dynamic drought risk assessment methodology. Hazard, vulnerability, and exposure indicators appropriate for monitoring drought in PNG provinces were selected. The risk assessment accurately indicated a strong drought event in 2015–2016 and a moderate event in 2019.
