Abstract:
U.S. Navy Marine Climatic Atlas is historical data set DSI-9757 archived at the National Climatic Data Center (NCDC). Surface Variables include: eight-point wind roses and means and standard deviations for wind force (speed), pressure, temperature, wet bulb, dewpoint, sea surface temperature, air-sea temperature difference and wave height. Also included are light and heavy superstructure icing
... potentials and the frequency of gales. The first of the climatological aids to be developed was the stability array, known as star. The star output consists off frequency and percent frequency tables of wind direction versus wind speed for each stability category. This system produces seven categories ranging from extremely unstable (a) to neutral (d) to extremely stable (g). These star data can be summarized on a monthly, seasonal, or annual basis. Without the influence of clouds, insolation (incoming radiation) during the day is dependent mainly upon the solar elevations, which is a function of time of year, time of day, and station location. When clouds exist, their cover and thickness decrease incoming and outgoing radiation. In this system, insolation is estimated by solar elevation and modified for existing conditions of total sky cover and ceiling height. At night, estimates of outgoing radiation are gain based on total sky cover and ceiling height. As with most meteorological sets of data, there are not enough reporting locations and there exist large differences in stability conditions over relatively short distances. Also, the thickness of the stability layer is unknown. This dataset covers January 1850 - December 1970. The period of record varies slightly depending on the ocean basin. These data are available for world-wide sites as well as for the 300 locations in the United States, with a latitude/longitude grid of 1-degree and 5-degree resolution and either on an hourly or three-hourly observational schedule.
