2. Optimization of water quality monitoring network
The aims of this monitoring program are to assess whether the fixed monitoring
sites now in use are truly optimal for effective water quality research and to optimize
the present system for better water quality management.
We do this by utilizing the results of research up to now in the Lake Biwa
hydrological and materials cycling model.
We also conduct water quality research in Lake Biwa to verify the results of earlier
studies and to investigate operational methods and problems.

3. Long-term changes in Lake Biwa's plankton
The aim of this monitoring program is to establish monitoring methods for
plankton in Lake Biwa. More specifically, we analyze the changes and biomass of
plankton facies. Furthermore, we evaluate the effects of such changes on water
quality by documenting the long-term changes in blue-green alga species
composition, abundance, and blooms in Lake Biwa.

4. Evaluation of current air quality status
The aim of this monitoring program is to investigate how to properly distribute and
install Continuous Atmospheric Monitoring Stations in order to issue timely
photochemical smog warnings to affected areas. To achieve this, we document and
analyze the current atmospheric conditions based on measurements of pollutant
concentrations and computer simulations of photochemical smog generation.
