CLIWOC Release 1.5 This file contains the full database in ASCII format and contains 280,280 records of variable length (file CLIWCOC15 is Unix compatible - ending with LF only -, while the file CLIWOC15.txt includes the character combination CR/LF for every record). Since this length may exceed three thousand characters, it is recommended to use either the Access version (97 or 2000) or the limited core version. The records are built according to the proposed format, given in the IMMA document, updated 20 February 2004 (www.cdc.noaa.gov/coads/e-doc/imma/imma.pdf). The idea behind this format is that the user can easily start with the data, without having to concern about unit conversions. The first 108 characters are the same as in the limited core version CLIWOC15corelimit.txt, then an identification for the attachment and the attachment itself follows. The attachment is delimited with a semi-colon (;), starting at character 114 the actual attachment begins. The explanation of the fields (separated by a semi-colon) is given below.
All data has been expressed in present day SI-units (e.g. UTC, Celsius, nautical miles, degrees, m/s and hPa). In the process of keying the data from different sources, duplicate records may have been keyed when more than one source was available from the same voyage. Usually these records are not exact copies, but are more or less complementary to each other. The identification of the duplicates is handled in the ShipLogbookID file (ShipLogbookIid.txt). If the user wants to avoid duplicates, he/she has to ignore those ID’s that have the Duplicate-field in the ShipLogbookID file set to other values than 0.

In the following tables the record in the file CLIWOC15.txt are explained.

Variable | Start | End | Format | Description
YR | 1 | 4 | A4 | Year (UTC)
MO | 5 | 6 | A2 | Month (UTC)
DY | 7 | 8 | A2 | Day (UTC)

ID | 35 | 43 | A9 | Identification; In this release a number is given that identifies the ship and the ships' logbook and the possibility that the current record is a duplicate. With this number you can look up this information in the file: ShipLogbookId.txt
C1 | 44 | 45 | A2 | Country code; gives the nationality of the ship that made the observation: ES = Spain FR = France NL = The Netherlands UK = United Kingdom SE = Sweden US = USA DE = Germany, in this case especially it is restricted to Hamburg DK = Denmark

W | 51 | 53 | A3 | Wind speed; given in tenths of a meter per second. From the descriptive terms of wind force given in the observations, a first division into “Beaufort” classes resulted in the m/s given here. Most of the values are the midpoints of each Beaufort class, cf. WMO-1100. In those cases that more information was available, other values may have been used.
