ATM bands marked bad suspiciously

[benj]

Some ATM lines for IPY have bad bands marked for some lines. However, the bad parts seem to correlate with areas where there is bright sunshine shining on white snow - in other words where the value is going to be pretty close to max. It's possible either this is incorrectly causing it to be classified as bad, or else that the max value is itself being used to mark bad data.

Eg. Green Box line 1:
