The frames omitted from lines 6 and 7 are ascribable to excessive cloud
cover. Flightlines 8 and 9, however, are cloud-free and show better radiometric
balance. The July 2002 imagery shows generally good radiometric balance with
only one small area of cloud shadows near the center of flightlines 6 and 7.
