Surface Marine Observations (DSI-1127)

[ Update this Record ]

Summary
Abstract: 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.


Purpose: To make a wide range of climatic data
available to researchers and the public. SUPPLEMENTAL

Quality
ATTRIBUTE ACCURACY REPORT: 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. APPENDIX: TESTS PERFORMED BY QUALITY CONTROL PROGRAM SHIP POSITION (One flag shred by
