This document discusses the pricing of public sector information (PSI) in the meteorological sector in Europe and how it blocks market development. It notes that national meteorological services have a monopoly on data and charge high prices for licenses and data, making it difficult for private sector companies to be profitable. As a result, the weather market in Europe is less than half the size it could be. The document calls for PSI to be more freely available and for governments to remove themselves from directly competing in the weather market.
