Parameter(s):

#	Name	Short Name	Unit	Comment
1	DATE/TIME	Date/Time		Geocode
2	LATITUDE	Latitude		Geocode
3	LONGITUDE	Longitude		Geocode
4	Wind direction	dd	deg	Wind direction (from which the wind is blowing) in whole degrees from: 1-360; 361 = calm, 362 = variable. It is not clear from many logbook entries whether the wind direction has been corrected for the magnetic variation (or declination). To avoid any misunderstanding, all winds from reports that included a valid position in the period 1750-1854 were corrected. All other wind directions are given without being corrected.
5	Wind speed	ff	m/s	calculated from the descriptive terms of wind force given in the observations
6	Pressure, atmospheric	PPPP	hPa	No temperature correction was applied. The following factors have been used for the conversion to hPa: 2.54 cm in an inch; 13.596 specific gravity of mercury; 980.65 cm/s gravity at 45° latitude
7	Temperature, air	TTT	°C
8	Landmark	Landmark		Name of first landmark
9	Bearing	Bearing		Bearing of the first landmark
10	-	-		1 If position is considered to be coastal (in port or near coastal disturbances)
11	Watch	Watch		Name of the period of 4 hours which is known as a watch or duty on board ships
12	Glasses	Glasses		Number of glasses within a watch; one watch equals 8 glasses
13	Course	Course		Course of the ship during the past 24 hours
14	Distance	Distance	arbitrary units	Distance travelled during the previous 24 hours
15	Comment	Comment		Other remarks, that were not possible to put in the other remark fields
16	Declination	Decl	deg	It is generally accepted by the CLIWOC team that the wind directions, reported by the ships officers, were relative to the magnetic North direction. Navigators were well aware of the difference between the true and magnetic north direction, but the compasses (we assumed that the bearing-compasses were mostly used for determining the wind direction) were not always adjusted. Therefore the wind direction has to be corrected. The magnetic declination (or variation, as it is known on board ships) is given for the whole CLIWOC period (1750-1850) for every 5x5 degree square. The number was added to the wind direction to get the true wind direction.
17	Sensor reading	Reading	arbitrary units	Reading of the (outside) air thermometer
18	Sensor reading	Reading	arbitrary units	Reading of the air pressure
19	Wind direction description	Wind dir descr		All reported wind directions on this day. The wind direction is the direction that points to where the wind comes from.
20	Wind force description	Wind force descr		All reported wind forces on this day
21	Cloud type	Cloud type
22	Gusts	Gusts		1 If wind gusts are reported
23	Precipitation/Rain	Rain		1 If rain was reported
24	Fog	Fog		1 If fog was reported
25	Snow type	Snow		1 If snow was reported
26	Thunder	Thunder		1 If thunder and or lightning was reported
27	Hail	Hail		1 If hail was reported
28	Sea ice	Sea ice		1 If sea-ice or icebergs were reported
29	Identification	ID		CLIWOC 2.1 line number
