Summary of Synoptic Meteorological Observations (SSMO), Alaska Coastal Marine Area, Valdez Marine Area, Valdez, Cape Hinchinbrook.
Abstract
The data contained in these tables were obtained from Tape Data Family (TDF-11), Marine Surface Observations, and Tape Data Family 14 (TDF-14), Land Surface Observations. Data for Valdez and Cape Hinchinbrook were edited and keyed to magnetic tape for a ten year period: Valdez hourly observations varied from 0800-1600 LST to 0500-2000 LST for the period July 1967-June 1977; Cape Hinchinbrook observations were three hourly observations from 0100-1900 LST (excluding 1600 LST) for the period July 1964-June 1974. The marine area in this volume is defined 59 deg N to Alaska's Coast, 144-149 deg W. The marine data contains weather observations taken aboard vessels of varying registry over the period 1929-1977. An automated/visual quality control of the marine data was made and, where possible, missing psychrometric data were computed. It should be noted that the marine area data are based upon observations made by ships in passage. Such ships tend to avoid bad weather when possible, thus biasing our data toward good weather samples. The primary period of record is that period (extending back in time from the most recent data) during which eighty percent of the total number of observations were recorded. The overall period is the earliest to the latest observed data used in compiling the tables.
