Hi, anyone,
It is fined to see the cool streaming generated by the Surface LIC, but the noise comes together is unlikely to visualize the data very well.
Would anyone propose the way to eliminate it or provide the explanation?

Try changing the **Mask Threshold** to a value higher than 0 to mask such regions out.
