HAL also was at the top the list in 2008 and 2006.
Among individual ships providing data, Oosterdam led the HAL fleet with 2,858 observations. Zaandam, Volendam, Zuiderdam and Amsterdam also were among the Top 10.
Despite the proliferation of weather satellites and ground stations, regular weather reports from ships are still of great value to meteorological and hydrological services around the world in preparing daily weather predictions. These weather reports also provide important climatological data to the World Weather Information Service of the World Meteorological Organization.
