Paper Abstract

The importance of calibrating optical open-path measurements of atmospheric gases is discussed. Work carried out at NPL has involved calibrating integrated-path and range- resolved measurement instruments. The designs of the calibration gas cells used for this work are described and some results are presented. These results include the calibration of a DIAL measurement system using a calibration cell in which a stable flow of the target gas is maintained.
