本研究创建全球火灾数据集,利用分割深度学习模型提前8至64天预测全球燃烧区域,为全球野火预测提供新方法。

摘要:

气候变化预计将通过加剧火灾天气条件而使野火活动更加严重。提升我们在全球范围内预测野火的能力,对于减轻其负面影响至关重要。在这项工作中,我们创建了一个全球火灾数据集,并展示了一个原型,该原型利用分割深度学习模型在亚季节尺度上预测全球燃烧区域的存在。具体而言,我们提出了一个开放获取的全球分析就绪数据立方体,其中包含与季节性和亚季节性火灾驱动因素(气候、植被、海洋指数、人类相关变量)相关的多种变量,以及2001-2021年的历史燃烧区域和野火排放数据。我们训练了一个深度学习模型,该模型将全球野火预测视为图像分割任务,并能提前8、16、32和64天熟练地预测燃烧区域的存在。我们的工作推动了深度学习在全球燃烧区域预测中的应用,并为改进全球野火模式的预测铺平了道路。

英文摘要:

Climate change is expected to aggravate wildfire activity through the exacerbation of fire weather. Improving our capabilities to anticipate wildfires on a global scale is of uttermost importance for mitigating their negative effects. In this work, we create a global fire dataset and demonstrate a prototype for predicting the presence of global burned areas on a sub-seasonal scale with the use of segmentation deep learning models. Particularly, we present an open-access global analysis-ready datacube, which contains a variety of variables related to the seasonal and sub-seasonal fire drivers (climate, vegetation, oceanic indices, human-related variables), as well as the historical burned areas and wildfire emissions for 2001-2021. We train a deep learning model, which treats global wildfire forecasting as an image segmentation task and skillfully predicts the presence of burned areas 8, 16, 32 and 64 days ahead of time. Our work motivates the use of deep learning for global burned area forecasting and paves the way towards improved anticipation of global wildfire patterns.
