Logbooks from the English East India Company voyages digitized in keyed format from 1789 to 1834

This collection of keyed Logbooks from the East India Company voyages are formatted in a common digitized format. Data include daily instrumental measurements and weather observations from 1789 to 1834. Primary logbook elements (mainly daily data) include Latitude/Longitude (at noon), Ship's Course and Distance Traveled (at noon), Barometer (at noon), Air Temperature (at noon), Sea Surface Temperature (at noon), Sympiesometer (at noon), Wind Direction and Force (closest to noon), State of Weather/Visibility (all available), and State of Sea (all available). The physical logbooks originated from the India Office Records and Private Papers archived at the British Library. Approximately 893 EIC marine logbooks were keyed into digital formats by Climate Database Modernization Program (CDMP) from copies rescued and imaged by the British Library. The data will be organized by ship and labeled with an observational date range. These logbooks are a unique source of meteorological information for a period and an ocean area with historically sparse coverage. Images of 1,235 EIC logbooks from the British Library are archived at NCDC. Only a subset (893 logbooks) containing instrumental data were keyed into digital form by CDMP.
