In Canada, forest fire is a critical disturbance. In the last 25 years, there have been on average 8300 fires annually. Each year on average 2.3 million hectares of forest have been burned. Though fire brings some advantages in enriching soil nutrients, killing insects and diseases, regenerating forests; however, it causes a significant amount of detrimental impacts. Those include: (i) economic loss due to burning of the trees and properties nearby the fire locations; (ii) increasing the carbon dioxide loading in the atmosphere; (iii) health hazard through air quality deterioration; and (iv) possible loss of human life in fighting large fires, among others. Also, every year on average Canada has spent CAD $500 million to $1 billion in fighting fires during the last decade. Thus, development of an efficient forest fire occurrence management system is crucial to develop sustainable fire management strategies in order to offset the adverse impacts. In this context, the intent is to use remote sensing data (in the form of digital imagery) acquired by the satellite platforms capable of gathering information over a large geographic area periodically.*******The overall goal of this proposed research program is to develop a forest fire occurrence management system. The foremost elements of the proposed research are the employment of remote sensing data to:****(i) enhance the recently developed remote sensing-based forest fire danger forecasting system;****(ii) determine land surface phenological stages at an enhanced temporal resolution (i.e., 2-day), and their relationships with fire occurrences;****(iii) model fire occurrences by combining the outcomes of the first two elements; and****(iv) develop fuel management strategies to reduce fire severity in the event of fire occurrences by using the outcomes of the first element and remote sensing-derived leaf area index data.*******The successful execution of this proposed research program will result in a prototype forest fire occurrence management system. It will be very useful in forest fire management; in sustainability and economics of forest resources; and in guiding research and codes in handling fire instances, among others. In addition, as a by-product of the proposed research program, the intent is to develop a Moderate Resolution Imaging Spectroradiometer (MODIS) image processing software package based on an open source platform; which will be made publicly available. Such action will proliferate the use of remote sensing data in natural resource and natural hazard/disaster management activities in Canada and elsewhere in the world.***

在加拿大，森林火灾是一种严重的干扰。在过去的25年里，每年平均发生8300起火灾。每年平均有230万公顷的森林被烧毁。虽然火在丰富土壤养分、杀灭病虫害、再生森林等方面具有一定的优势；然而，它造成了大量的有害影响。这些损失包括：(i)火灾地点附近的树木和财产被烧毁造成的经济损失；（二）增加大气中的二氧化碳负荷；（三）空气质量恶化对健康造成危害；（四）在扑灭大火等过程中可能造成的人员伤亡。此外，在过去十年中，加拿大每年平均花费5亿至10亿加元用于灭火。因此，开发有效的森林火灾发生管理系统对于制定可持续的火灾管理战略以抵消不利影响至关重要。在这方面，目的是利用能够定期收集大地理区域信息的卫星平台获得的遥感数据（以数字图像的形式）。*******这个研究计划的总体目标是开发一个森林火灾发生管理系统。拟议研究的最重要内容是利用遥感数据：****(i)加强最近发展的基于遥感的森林火险预报系统；****(ii)以增强的时间分辨率（即2天）确定陆地表面物候阶段及其与火灾发生的关系；****(iii)结合前两个要素的结果模拟火灾发生；****(iv)通过使用第一要素的结果和遥感衍生的叶面积指数数据，制定燃料管理策略，以在发生火灾时降低火灾的严重程度。*******这项拟议的研究计划的成功执行将产生一个森林火灾发生管理系统的原型。它将在森林火灾管理中非常有用；森林资源的可持续性和经济性；在指导研究和规范处理火灾等方面。此外，作为拟议研究计划的副产品，其目的是开发基于开源平台的中分辨率成像光谱仪（MODIS）图像处理软件包；这将是公开的。这种行动将扩大遥感数据在加拿大和世界其他地方的自然资源和自然灾害/灾害管理活动中的使用
