Google Earth Engine ——MODIS Terra/Aqua Daily BAI烧伤面积指数（BAI）

The Burn Area Index (BAI) is generated from the Red and Near-IR bands, and measures the spectral distance of each pixel from a reference spectral point (the measured reflectance of charcoal). This index is intended to emphasize the charcoal signal in post-fire images. See Chuvieco et al. (2002) for details. This product is generated from the MODIS/MOD09GA surface reflectance composites.

烧伤面积指数（BAI）由红色和近红外波段产生，测量每个像素与参考光谱点（测得的木炭反射率）的光谱距离。这个指数的目的是强调火后图像中的木炭信号。详见Chuvieco等人（2002）。该产品是由MODIS/MOD09GA表面反射率合成物生成的。
