Part III. Location and Frequency of Highly Reflective Clouds:
Normalized Monthly Data
These maps use numbers and letters in grid squares to show actual (or normalized) numbers of days per month with highly reflective clouds (HRC) for each month from January 1971 to December 1985 (180 months).
HRC data were normalized by the number of days in the month for which satellite data were available. For instance, if only 20 days of satellite data were available for a particular grid square during a 30-day month, and HRC occurrred on 10 days, the number shown on the maps is 15, or 10/20 x 30 days. In other words, since HRCs were recorded on half the days for which there were data, one would expect half the days in a full month to have HRC, assuming that the 20 days sampled were representative of the whole month. Relatively few grid square values were affected by the normalizing procedure.
