研究一场有计划的火灾
Flames burn orange through green conifers and golden aspen on the slopes of Monroe Mountain in Utah’s Fishlake National Forest, sending gray and brown smoke billowing into the sky in this image from Oct. 9, 2023.
This fire was intentionally set with a fire-dripping device suspended from a helicopter. The burn aimed to reintroduce fire to the Monroe Mountain region. Fire promotes aspen regeneration and reduces accumulated brush and dead vegetation that could fuel a larger uncontrolled fire.
Scientists from NASA’s FireSense project, along with dozens of others from the Forest Service and other organizations and universities, collected data from the ground and from the sky as part of the Forest Service’s Fire and Smoke Model Evaluation Experiment. Observing a prescribed high-intensity fire gave NASA an opportunity to test technologies and demonstrate their effectiveness in supporting wildland fire management across the life cycle of a fire.

2023年10月9日，犹他州鱼湖国家森林门罗山山坡上的绿色针叶树和金色白杨中，橙色的火焰燃烧着，将灰色和棕色的烟雾抛向天空。
这场火灾是故意用悬挂在直升机上的灭火装置引发的。这次燃烧旨在将大火重新引入门罗山区。火促进了白杨的再生，减少了堆积的灌木和枯死的植被，这可能会助长更大的失控火灾。
作为林务局火灾和烟雾模型评估实验的一部分，来自NASA FireSense项目的科学家，以及来自林务局和其他组织及大学的数十名其他科学家，从地面和天空收集数据。观察指定的高强度火灾给了NASA一个机会来测试技术并展示其在火灾生命周期中支持荒地火灾管理的有效性。
