We downloaded two scenes of sentinel 2A images adjacent to each other， the level is 2A, which was sensed on the same day. But those two scenes image have different refectance， anybody knows why？ Thanks
I think that for sentinel A we make atmospheric correction
But for sentinel B no atmospheric correction
Lamyaa Gamal El-deen Taha ，Hi thanks for your response! The two images were sensed by the same sensor, sentinel 2A. And data processed level is 2A. If they were sensed by two sensors, that's reseanable.
Dear Yunlong Yao ,
what is the time difference between the pick up of the two images?
In the meantime the direction (and intensity as well as the spectral distribution) of the sun light impinging on that area may have been significantly changed....
So I would not expect the same intensity distribution across your images or on adjacent areas of the two images.
