The individual images that are used as input into
this product sometimes contain bad data in the form of missing
scanlines or anamalously high or low values that often stretch in an
arc across the image. When these areas are incorporated into the MIMIC
product they form artifacts that fade in and out, and appear to move
with the storm center. However, they have no physical meaning and
hopefully they will not obstruct your interpretation of the imagery.
Please read the Product
