Description
Summary:In support of the NRDL Optical Sensor Study climatological charts are provided for the mid-season months of January, April, July and October for the North Atlantic, North Pacific and Indian Oceans. The climatological charts provide: (1) isovisic (visibility) maps of the percentage frequency of visibilities less than 25, 10, five, two and one nm; (2) isovisic maps of visibility for 90, 75, 50 and 25%; (3) nephanalysis maps of the percentage frequency of total cloud cover greater than or equal to seven eights (greater than or equal to 7/8); and (4) nephanalysis maps of percentage frequency of total cloud cover equal to or less than two tenths (less than or equal to 2/10).
