Surface Marine Observations (DSI-1127)
tabular digital data
http://www.ncdc.noaa.gov
Surface Marine Observations is historical
digital data set DSI-1127, archived at the National Climatic Data Center
(NCDC). The major parameters making up this file are sky condition,
visibility, present and past weather, wind speed and direction,
temperatures (both sea and air), sea and swell wave data, and pressure data.
This marine data file contains data from ship logs, ship weather reporting
forms, published ship observations, automatic observing buoys and teletype
reports from the U.S. and several foreign meteorological services. The
National Climatic Data Center (NCDC) began with the 1970's marine data, to
uniformly edit and merge these data into a single file. The resultant
DSI-1127 is a higher quality data base which provides more economical
service to users of surface marine data. Related files include Marine Data
DSI-1100 (C00001) maintained in the NCDC library. The NCDC reviewed all
available marine data sources for quality and uniqueness and selected only
those which added significantly to the 1970's decade dataset. The NCDC
corrected all known errors, converted the data to the common DSI-1127 format,
quality controlled the data, assembled the data from the different sources,
and eliminated duplicate observations. The 1970's decade files were sorted
and inventoried by 10 degree marsden squares (gridded map of the
marsden square numbering system can be obtained from NCDC). Much of the
processing software, including quality control tests, were originally
developed for the First GARP Global Experiment (FGGE) project at the NCDC.
To make a wide range of climatic data available to researchers
and the public.

Quality control procedures checked each marine
observation for internal consistency, extreme values, legal codes, and ship
position changes. The results of the editing are then passed to the user in
the form of quality indicators (flags). In this processing system the
original are left unchanged. Edited observation elements are: ship position
wind speed wind direction visibility present weather past weather pressure
tendency dry bulb dew point wet bulb sea temp air temp air-sea temp
difference clouds wind waves swell waves the sea surface temperature
indicator bucket or intake for U.S. ships was not well documented prior to
April 1973. The indicator (position 99) is reliable only for
observations taken after that date.
