NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Fire/Hot Spot Characterization (FDC)

The GOES-R Advanced Baseline Imager (ABI) Fire (HSC) product contains four images, one in the form of a fire mask, and the other three with pixel values identifying fire temperature, fire area, and fire radiative power. Pixel values in the fire mask image identify a fire category and diagnostic information associated with algorithm execution. The six fire categories include: Good quality or temporally filtered good quality fire pixel; Saturated fire pixel or temporally filtered saturated fire pixel; Cloud contaminated or temporally filtered cloud contaminated fire pixel; High probability or temporally filtered high probability fire pixel; Medium probability or temporally filtered high probability fire pixel; Low probability or temporally filtered high probability fire. Temporally filtered fire pixels are those resulting from fire pixels that are in close proximity in both space and time. The product includes data quality information that provides an assessment of fire detection for on-earth pixels. The units of measure for the Fire (HSC) product quantities are for Mask: dimensionless; for Temperature: kelvin; for Area: square kilometers; for Radiative Power: megawatts. The Fire (HSC) product image is produced on the ABI fixed grid at 2 km resolution for Full Disk and CONUS coverage regions from GOES East and West. Product data is produced under the following conditions: Existence of land; Geolocated source data to local zenith angles of 80 degrees, solar zenith angles between 10 and 180 degrees, and sunglint angles greater than 10 degrees.

GOES-R高级基准成像仪（ABI）火灾（HSC）产品包含四幅图像，其中一幅为火灾掩码图像，其余三幅图像包含识别火灾温度、火灾面积和火灾辐射功率的像素值。火灾掩码图像中的像素值确定了火灾类别及与算法执行相关的诊断信息。六个火灾类别包括：高质量或时间滤波后高质量火灾像素；饱和火灾像素或时间滤波后饱和火灾像素；云污染或时间滤波后云污染火灾像素；高概率或时间滤波后高概率火灾像素；中概率或时间滤波后高概率火灾像素；低概率或时间滤波后高概率火灾。时间滤波火灾像素是指空间和时间上紧密相邻的火灾像素。该产品包含数据质量信息，对地面像素的火灾检测进行评估。火灾（HSC）产品的测量单位为：掩码：无量纲；温度：开尔文；面积：平方公里；辐射功率：兆瓦。火灾（HSC）产品图像在ABI固定网格上以2公里分辨率生成，覆盖全圆盘和CONUS区域，数据来源于GOES东半球和西半球。产品数据在以下条件下生成：存在陆地；地理定位源数据至当地天顶角为80度，太阳天顶角在10至180度之间，太阳光反射角大于10度。
