Iono bad pairs

[ssharifi1994]

Hello friends,

I'm running alosStack to process a stack of ALOS-2 scenes. In cmd_3.sh, it's advised to exclude the bad pairs after iono estimation. An example in the tutorial is said to be dense fringes. I'd like to know your opinion on the attached estimation. Do you find this dense? NOTE: beside two small rivers going through, it's mostly land. The watermask is also attached for your reference.

Hi ssharifi1994

That ionospheric correction is not doing what it is supposed to do because it is introducing a dense band of fringes in a region where they are absent in the uncorrected interferogram. When properly corrected, it should look like the following example.
