The WMO have recently released a new technical report, "Guidelines for Hydrological Data Rescue", authored by Matt Fry of the NRFA. Data loss, often due to deterioration of records, is a huge problem around the world. The guidelines highlight key issues of importance when rescuing hydrological data, and draw on a wide range of existing material to help those embarking on data rescue projects to plan appropriately and ensure data can be made accessible and usable.
