MODIS/TERRA MOD14A1 Thermal Anomalies & Fire Daily L3 Global 1km Version 6

MODIS Thermal Anomalies/Fire products are primarily derived from MODIS 4- and 11-micrometer radiances. The fire detection strategy is based on absolute detection of a fire (when the fire strength is sufficient to detect), and on detection relative to its background (to account for variability of the surface temperature and reflection by sunlight). Numerous tests are employed to reject typical false alarm sources like sun glint or an unmasked coastline. Information on individual MODIS Thermal Anomalies and Fire Products along with improvements/changes for Version 6 are available at: https://lpdaac.usgs.gov/dataset_discovery/?f[0]=im_field_dataset_version%3A32&f[1]=im_field_product%3A12.

中分辨率成像光谱仪（MODIS）热异常/火灾产品主要基于MODIS的4微米与11微米波段辐射亮度数据反演生成。其火灾探测策略兼顾两种模式：当火灾强度足以被探测时采用绝对探测，同时结合相对背景环境的探测方式，以抵消地表温度波动与太阳反射带来的干扰。研究采用多种测试手段以剔除典型误报源，例如太阳耀斑或未掩膜海岸线。各款MODIS热异常/火灾产品的详细信息以及第6版（Version 6）的更新与调整内容，可通过以下链接获取：https://lpdaac.usgs.gov/dataset_discovery/?f[0]=im_field_dataset_version%3A32&f[1]=im_field_product%3A12
