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. Wind speed [m/s] (ff) * COMMENT: calculated from the descriptive terms of wind force given in the observations Landmark (Landmark) * COMMENT: Name of first landmark Bearing (Bearing) * COMMENT: Bearing of the first landmark Distance to landmark [arbitrary units] (Distance) * COMMENT: Distance to the first landmark Course (Course) * COMMENT: Course of the ship during the past 24 hours Distance [arbitrary units] (Distance) * COMMENT: Distance travelled during the previous 24 hours Declination [deg] (Decl) * COMMENT: 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. Wind direction description (Wind dir descr) * COMMENT: All reported wind directions on this day. The wind direction is the direction that points to where the wind comes from. Wind force description (Wind force descr) * COMMENT: All reported wind forces on this day Precipitation description (Precip descr) Clearness (Clearness) Gusts (Gusts) * COMMENT: 1 If wind gusts are reported Precipitation/Rain (Rain) * COMMENT: 1 If rain was reported Fog (Fog) * COMMENT: 1 If fog was reported Snow type (Snow) * COMMENT: 1 If snow was reported Thunder (Thunder) * COMMENT: 1 If thunder and or lightning was reported Hail (Hail) * COMMENT: 1 If hail was reported Sea ice (Sea ice) * COMMENT: 1 If sea-ice or icebergs were reported Identification (ID) * COMMENT: CLIWOC 2.1 line number License: Creative Commons Attribution 3.0 Unported (CC-BY-3.0) (URI: https://creativecommons.org/licenses/by/3.0/) Size: 127 data points */ Date/Time Latitude Longitude dd [deg] (Wind direction (from which th...) ff [m/s] (calculated from the descripti...)
