Analysis of Statistical Parameters Derived from Satellite Digital Data (July 1978 GOES-West) for Use in Diagnosing Marine Fog Areas.
Abstract
GOES West Infrared (IR) and Visual (VIS) satellite observations for the North Pacific Ocean area, 35-55N, 120W-180, at 2345 GMT for eight June/July 1978 dates are processed to yield 20 statistical parameters which are analyzed for their use in discerning the existence of marine fog. The exploratory sample of 522 satellite observations, at 3 nmi x 3 nmi resolution (at subsatellite point) are related to the associated 0000 GMT synoptic ship reports which serve the role of ground truth. The best discrimination between fog/no-fog observations, using the statistical parameters, occurs for stratification of the data by the meridional component of the wind (south vs north), IR temperature (> or = 269 K vs < 269 K) and the standard deviation of IR temperature (< or = 2 K vs > 2 K).
