Guidelines on climate data rescue

Summary

This technical document is an update of WMO/TD-1210, WCDMP-55, Guidelines on Climate Data Rescue (2004). It builds on the original Guidelines, while taking into account both changes in technology that have occurred in the intervening 12 years and lessons learned in more recent climate data rescue activities around the world. An overview of data rescue is presented with chapters on its importance, archiving original media, imaging, digitization and archiving digital images and digital data. Twelve appendices provide supporting information. The Guidelines on Climate Data Rescue are intended to provide guidance in the form of recommended best practices. Because of the diversity of National Meteorological and Hydrological Services (NMHS) with respect to the size and stage of technological development, along with the variability of weather types and climate, some practices may not be useful for every WMO Member.
