Trabajo presentado en el EMS Annual Meeting: European Conference for Applied Meteorology and Climatology, celebrado en Budapest (Hungría), del 3 al 7 de 2018 Wind direction provided by ships’ logbooks is a consolidated instrumental source, as it has been measured with a compass for many centuries, thus yielding daily observations for the world’s oceans and seas.
