Standardisation work on ground-based remote-sensing techniques in Germany

Ground-based remote-sensing systems, designed for environmental meteorology, are increasingly forced to have their results certified according to the criteria of present-day quality assurance. To this aim, the need for dedicated guidelines is growing and the German Commission on Air Pollution Prevention has been active in this field for more than a decade now. The present paper gives a brief account of the intended purpose, and of the procedure followed to get the guidelines written, discussed, approved, and issued. As an example, parts of the ongoing work on the Raman lidar guideline are presented, including measuring examples provided by the German Meteorological Service in Lindenberg.
