Abstract
A differential-absorption lidar facility has been developed by the National Physical Laboratory and mounted in a custom-built vehicle. It is now being deployed in a range of field measurement exercises. The facility operates in either a mobile or a stationary scanning mode. It is presently capable of range-resolved measurements of the atmospheric concentrations of NO, NO2, SO2 and O3 in the troposphere in the visible and ultraviolet regions of the spectrum. The system can be configured to monitor up to three species near-simultaneously and is currently being extended so that it can be operated in the infrared.
