Therefore, histograms built using "qc_ReflectivityClutterFlag = 1 and 2" may overestimate cloud amount because clutter may be identified as cloud, whereas those based on "qc_ReflectivityClutterFlag = 1" may underestimate cloud amount because some hydrometeors potentially contaminated by clutter were not incorporated into the histograms.
