Satellite-Aided Disaster Response

Abstract

The increasing frequency and severity of natural disasters, driven by climate change and anthropogenic activities, pose unprecedented challenges to emergency response agencies worldwide. Satellite remote sensing has become a critical tool for providing timely and accurate data to aid in disaster preparedness, response, and recovery. This Commentary explores the role of satellite remote sensing in managing climate-driven disasters, highlighting the use of technologies such as Synthetic Aperture Radar (SAR) for creating damage proxy maps. These maps are instrumental in assessing disaster impacts and guiding response efforts, as demonstrated by the 2023 Wildfires in Hawaii. Despite the promise of these tools, challenges remain, including the need for rapid data processing, automation in data pipelines, and robust international collaborations. The future missions composing the Earth System Observatory, including the upcoming NASA-ISRO SAR mission, represents a significant advancement with its global coverage and frequent, detailed measurements. This study emphasizes the importance of continued investment in advanced satellite technologies and international cooperation to enhance disaster response capabilities, ultimately building a more resilient global community.
