利用单偏振天气雷达实时追踪沙漠蝗群，提前7小时预警
Harnessing single polarization doppler weather radars for tracking Desert Locust Swarms
- 基于现有天气雷达数据，开发识别蝗群的新算法
- 可实现约7小时预警期，覆盖范围达100公里
- 适合农业监测与灾害预警机构使用
沙漠蝗虫是臭名昭著的农业害虫，每年造成数十亿美元损失并引发全球粮食安全担忧。随着数亿只蝗虫持续侵袭农田，这一威胁已不再是历史。本研究利用原本用于气象观测的单偏振多普勒天气雷达（DWR）基础设施，提出一种系统性方法，可在近实时条件下准确识别并追踪沙漠蝗群聚集区。结果表明，该方法具备约7小时的预警提前量，空间覆盖范围可达约100公里。这些技术进步对保护农业景观、维护全球粮食安全具有重要意义。
原文摘要 · Abstract (English)
Desert locusts are notorious agriculture pests prompting billions in losses and global food scarcity concerns. With billions of these locusts invading agrarian lands, this is no longer a thing of the past. This study taps into the existing doppler weather radar (DWR) infrastructure which was originally deployed for meteorological applications. This study demonstrates a systematic approach to distinctly identify and track concentrations of desert locust swarms in near real time using single polarization radars. Findings reveal the potential to establish early warning systems with lead times of around 7 hours and spatial coverage of approximately 100 kilometers. Embracing these technological advancements are crucial to safeguard agricultural landscapes and upload global food security.
