Project summary

The atmospheric pollutants monitoring is a task of primary importance in today's world. For FSU countries the activities in the field is motivated by considerable content of atmospheric pollutants over wide industrial and urban areas and rather high probability of industrial emergencies with emission of toxic species.

The powerful tools for the atmospheric pollution monitoring are mobile lidar systems based on application of tunable laser sources. The utilization of lidar system provides yielding range-resolved, molecular-specific information of gaseous species and three-dimentional mapping of the pollutants.

The objective of the proposed Project is design, construction and testing of mobile lidar system for range-resolved measuring of atmospheric pollutants using the differential absorption lidar (DIAL) techniques. The concept of lidar system is based on utilization of narrowband tunable dye laser pumped by excimer laser. A generation of the UV sensing radiation is provided by frequency doubling in non-linear crystals. The lidar system (including optics, electronics, steering units etc.) is implanted in a full-size truck (van).

During the system development, the advanced apparatus, units and facilities having been developed for military and double purpose applications will be utilized making the cost of the project lower. The peculiarity of the proposal consists in making use of the excimer laser as pumping source. XeCl pump-laser to be used was developed for the operation in difficult (vibrational, thermal etc.) conditions and is the only excimer laser which has been already tested upon national standards for space instrumentation.

Sulfur dioxide (SO2) and atomic mercury (Hg) are selected as a basic pollutants for the field test studies by lidar system under development. Successful results from this phase of activity would lead to next stage of the work. In future it would be possible to start a production of mobile environmental lidars for monitoring of anthropogenic gaseous pollutants or for scientific (e.g. geophysical) studies.

For Russian Federation and CIS countries taking into account relatively low funding of environmental services, the design and construction of lidar system under financial support of ISTC would be of essential importance. Realization of the project would provide the opportunity for weapon development specialists to use their experience in fundamental and applied studies and to utilize available equipment and "know-how" in peaceful uses e.g. a conservation of a healthy environment.
