Description
Summary:The longest instrumental index of the North Atlantic Os-cillation (NAO) is based on pressure measurements from Gibraltar and Reykjavik. Recently two long pressure series from the town of Cádiz and the nearby San Fernando obser-vatory in southern Spain have been digitized. As Gibraltar is situated within 100 kilometers from Cádiz and San Fer-nando a long held suspicion that early pressure data from Gibraltar contains several problems can now be investigated. This leads to the creation of an improved version of the long
