Project summary

The Project purposes are to create scientific, engineering and methodological foundations to develop lidar network CIS-LiNet in CIS regions, to design a technology for atmospheric lidar monitoring and its demonstration while tracking atmospheric aerosols and ozone in CIS, and to perform common atmospheric investigations with EARLINET, AD-Net, and AERONET/PHOTONS at the Eurasian continent.

The state of the art in the field: An important prerequisite to validly forecast climatic changes and solve ecological problems is atmospheric aerosol and ozone monitoring. Network stations of the WMO Global Atmosphere Watch (GAW) system implement detailed aerosol and ozone investigations. Global Aerosol Robotic Network (AERONET/PHOTONS) has been created and is being further to monitor aerosol parameters on the base of Sun-scanning radiometers. Lidar systems are used as an effective tool to follow altitude distributions of atmospheric components. The network NDSC (Network for the Detection of Stratospheric Change) is arranged to investigate stratospheric aerosols and ozone, and comprises lidar stations. Regional lidar networks are being formed to monitor tropospheric aerosols. In 2000, the European Aerosol Research Lidar Network (EARLINET) has been created to coordinate the operation of 24 lidar stations to monitor large-scale aerosol transport in the European region and the investigations of aerosol effects on climate and ecological conditions. Lidar studies of Asian dust outbursts to the Pacific Ocean regions are being made within the scope of the Asian Dust Network (AD-Net).

A whole community of highly skilled scientific and engineering teams was engaged in designing methods and equipment for laser sounding in the Former SU. A number of CIS institutions are currently making field investigations of the atmosphere. There exist however no coordinated lidar observations carried out commonly with International networks at the CIS territory, except those made by the lidar station of the Institute of Physics, National Academy of Sciences of Belarus within the scope of the EARLINET network. The absence of the systematic data on parameters of atmospheric components in this region is a critical factor introducing the ambiguities to prevent from forecasting of climatic and ecological changes.

The impact of the proposed project on the progress in this field: The Project execution would crucially change the situation. A network for remote atmospheric monitoring will be arranged on the base of multi-frequency lidar systems operating commonly with Sun radiometers at the territory of CIS countries. In cooperation with EARLINET, AD-Net, and AERONET/PHOTONS, there will be implemented programs of routine and dedicated observations of the characteristics of the aerosol and ozone layer to solve regional and global climatic and ecological problems. A qualitatively new stage of the evolution of the atmospheric lidar monitoring system, i.e. coordinated observations at the territory of the Eurasian continent, will be gained to provide an opportunity to study atmospheric processes of the global scale.

Competence of the project team in the specified area: The scientific groups of six institutions of Belarus, Russia, and Kyrgyz Republic, being the leaders in the development of lidar technologies in CIS countries, will execute the Project. The Project Executors have big experience in lidar investigations, possess the required scientific and engineering base, and are currently implementing routine field measurements. The geographical positions of the stations will provide success in monitoring objectives. The Executive team includes 9 Doctors of Sciences and 21 Candidate of Sciences, who are the experts in the field of designing the observation methods and systems, of optical sounding and atmospheric optics. The team includes 36 weapon specialists playing crucial roles in the Project, who earlier have been engaged in the developments of guidance, detection and tracking methods and systems in the fields of missile technologies and application of powerful laser devices.

Project Manager, Head of Scientific Group, Leading Research Scientist of the Institute of Physics, National Academy of Sciences of Belarus, Winner of the 2002 Belarus State Prize, Candidate of Physical and Mathematical Sciences Chaikovsky A.P. is an expert in the field of laser light propagation through the atmosphere, laser sounding, guidance, detection and tracking systems, and optical engineering. Under his supervision, the IP scientific group is working as a part of the lidar network EARLINET since 2000.

Expected results: The Project belongs to the area of applied researches, technology development and demonstration. The tasks of the Project Working Program envisage the development of the main components of the system to monitor the atmosphere, the design of the monitoring technology and its approval via routine observations. The expected results of the Project execution will be the following:

1. Creation of a complex of multi-wavelength lidar stations with unified device modules to arrange a CIS lidar network.

2. New methods, algorithms, and software to retrieve altitude profiles of optical and microphysical aerosol parameters by routine and dedicated multi-frequency lidar measurements made commonly with radiometric observations.

3. A procedure to monitor altitude profiles of tropospheric aerosols and demonstration of results of its application while investigate factors determining large-scale transformations of tropospheric aerosol parameters in the CIS region.

4. A procedure to monitor the atmospheric boundary layer and quantitative data on temporal transformations of aerosols in this layer with temporal cycles from daily to seasonal ones for a variety of geophysical regions.

5. Relations describing spatial and temporal transformations of altitude aerosol profiles during large-scale transport over the CIS territory and estimations of the contributions of main anthropogenic and natural aerosol sources.

6. A procedure to monitor the stratospheric layer and demonstration of its applicability to estimate temporal trends of aerosol and ozone contents in the stratosphere under impacts of anthropogenic and natural factors.

7. Features in formation of aerosol fields in the CIS regions, description and estimation of regional aerosol sources.

8. Database on altitude profiles of aerosol and ozone parameters to adequately characterize their spatial and temporal variations at the CIS territory.

9. Design of a CIS-LiNet web site and refinement of a procedure to distribute information gathered by CIS-LiNet operation.

The main Project total will be the development of a lidar station network at the huge CIS territory providing the atmospheric monitoring at the Eurasian continent in cooperation with International measurement networks.

Application of the Project results: The CIS-LiNet arranged during the Project execution will implement its activities within the scope of International and National programs on environmental monitoring. The results of the investigations of aerosol and ozone parameters in CIS regions, being combined in a database, will be used to further develop optical atmospheric models, validly describe the energy balance and improve the climatic models, estimate contributions of aerosol sources at the CIS territory to the formation of the global atmospheric aerosol layer. The data of dedicated field experiments will be applied to refine models of large-scale atmospheric transport and validate space experiments.

Implementation of the ISTC aims and tasks: The Project is in full conformity with the ISTC aims and tasks:

- Execution of the Project would provide to “weapon” experts, participating in it, opportunities to redirect their talents to peaceful activities by fulfilling jobs for arranging a global environmental monitoring system and effective usage of natural resources.

- Activities on the CIS-LiNet network development will contribute to the integration of participating scientists to carrying out global ecological programs in close cooperation with EC, USA and Japan scientific teams.

- The expected Project results will support the progress of investigations and technologies in the field of environmental safety and assist to the solution of a variety of National and International ecological programs.

- Execution of the Project will promote to the transition of scientific groups participating in the Project to the market based economics. After the Project completion, scientific groups of the CIS-LiNet will continue their activities on providing information services, them being financed within International ecological and climatological programs and while establishing direct contacts with National environmental safety institutions.

Total Project efforts are 11150 person*days. The duration is 3 years. All the institutions participating in the Project will provide technical foundations to put the network into operation, will implement the programs of routine and dedicated observations. The leading role in designing the methodology of the monitoring, the respective procedures, algorithms, and software will belong to the IP and IAO.

The role of foreign Collaborators: The Collaborators of the Projects are the Coordinators of the measurement networks EARLINET, AD-Net, and AERONET/PHOTONS that monitor the atmosphere at the Eurasian continent and represent the scientific groups from the USA, EC, Japan, China, Republic of Korea, and other countries. The Project envisages the following:

- Exchanging information with Collaborators concerning engineering solutions obtained, measurement procedures, software, results of field observations as well as the creation of common databases.

- Providing equipment by the Collaborators for carrying out measurements and joint application of the results obtained.

- Execution of common programs of field measurements and cross-checks of results obtained in the course of investigations.

- Participation of Collaborator representatives in testing the equipment and procedures designed according to the Project.

- Joint seminars and workshops, preparation of common publications on the Project results.

Technical approach and methodology of the Project: The methodology to arrange the CIS-LiNet is oriented towards the creation of a regional measurement network, which will provide monitoring of large-scale aerosol and ozone transformations in the CIS countries and will be capable to become a part of the global network for lidar environmental monitoring. The CIS-LiNet network will include seven stations located at the space from the Western CIS borders (Minsk, Belarus) to the Far East (Vlapostok, Russia), from the south (Teplokluchenka, Kyrgyz Republic) to north (Surgut, Russia) regions. The foundations for the methodological approach are the design and application of the methods for multi-frequency atmospheric lidar sounding, including Raman channels, in combination with radiometric measurements. The engineering, methodological and information components of the CIS-LiNet will be created according to the requirements and standards adopted by the measurement networks of the Project Collaborators.
