澳大利亚丛林火灾季节即将来临,地球科学局推出了一项基于欧洲太空署Sentinel-2卫星数据的新型监测工具,帮助社区和土地管理者评估本地火灾风险。1这一工具通过20米分辨率的卫星观测覆盖全澳大利亚,每5天更新一次观测数据,历史数据可溯源至2015年。1
该工具专门监测植被含水量的变化,为防灾准备工作提供重要参考。1澳大利亚及太平洋地区消防与应急服务当局委员会在8月发布的《全国季节性丛林火灾展望》表明,火灾风险评估工作已进入关键阶段。1
以澳大利亚首都领地为例,2026年8月超过一半的地区植被含水量至少与历年平均水平相当,但南部地区呈现特别干燥的状况。1在2026年7月至8月期间,该地区植被的干燥速度比过去十年大多数时期都要快。1
Australia's bushfire season is rapidly approaching, and a newly released satellite monitoring system aims to give communities and land managers better visibility into local fire risks.1 Geosciences Australia has unveiled a tool that leverages data from the European Space Agency's Sentinel-2 satellite to track vegetation moisture content across the country.1 The system provides high-resolution monitoring at 20-meter precision, with fresh observational data updated approximately every five days, while historical records extend back to 2015.1
The National Seasonal Bushfire Outlook, released by the Australasian Fire and Emergency Service Authorities Council in August, sets the stage for enhanced preparedness efforts.1 Real-world data from the Australian Capital Territory demonstrates the tool's practical application: in August 2026, more than half of the territory's vegetation maintained moisture levels at or above historical averages, though southern regions showed notably drier conditions.1 Between July and August 2026, vegetation dried at a pace faster than most periods over the preceding decade, highlighting the dynamic fire risk landscape the new monitoring system can help communities navigate.1
