使用辐射传输模型对两幅中分辨率成像光谱仪 (MERIS) 图像中太阳闪烁的强度和位置进行建模，其中包括高程特征以及海面坡度。将结果与使用标准大气校正处理代码中使用的闪烁标记和校正方法进行的估计进行比较。该模型估计给出的闪烁图案具有相似的宽度，但峰值水平低于任何当前方法，或者比具有包括坡度但不包括高度的表面的辐射传输模型估计的闪烁图案。 MERIS第三次后处理最近采用了新的斜率统计模型来进行太阳闪烁校正；结果表明，该模型相对于高程模型和其他坡度统计模型来说都是异常值，我们建议对其采用进行审查。
The intensity and location of Sun glint in two Medium Resolution Imaging Spectrometer (MERIS) images was modeled using a radiative transfer model that includes elevation features as well as the slope of the sea surface. The results are compared to estimates made using glint flagging and correction approaches used within standard atmospheric correction processing code. The model estimate gives a glint pattern with a similar width but lower peak level than any current method, or than that estimated by a radiative transfer model with surfaces that include slope but not height. The MERIS third reprocessing recently adopted a new slope statistics model for Sun glint correction; the results show that this model is an outlier with respect to both the elevation model and other slope statistics models and we recommend that its adoption should be reviewed.
