Global Environment

  • The Global Environmental Database serves as a fundamental database of the Center for Global Environmental Research at NIES. The GED disseminates research data and results related to global environmental problems with an emphasis on global warming and climate change. Near real-time monitoring data of greenhouse-gases and online analysis tools (e.g. CGER METEX: trajectory calculation) are also available.

Climate Change

Stratospheric Ozone

  • Providing information on ultraviolet radiation, including UV index, for 14 sites in Japan on hourly basis. A website for cellular phone is also available.
  • Forecast of the position, shape, and size of the polar air-mass in the stratosphere. It is displayed in terms of potential vorticity maps calculated by CGER, using the National Center for Environmental Prediction (NCEP) weather forecast data.
  • UV radiation contains erythemally-weighted UV, as well as UV that synthesizes vitamin D3. Here the time to reach the MED and that needed to produce 10 μg of vitamin D for various sites across the Japanese Archipelago, is shown which will enable people to effectively manage their UV exposure and consider the risks and benefits of UV radiation.

Hydrology / Water Resources

  • The global water resources model H08 is a distributed hydrological model designed for global application. The model enables us to simulate not only natural terrestrial hydrological cycle but also major human activities at high spatial and temporal resolutions. Source code, manuals, and meteorological input data of H08 are available.

Health / Chemical Substance

  • KATE (KAshinhou(*) Tool for Ecotoxicity) is an ecotoxicity prediction system that consists of quantitative structure-activity relationship (QSAR) models. KATE is being developed with the aim of predicting acute and chronic toxicity to fish, daphnia, and algae. (*)Chemical Substance Control Law in Japanese
  • Environmental Certified Reference Materials (CRMs) are utilized to evaluate new analytical methods and to control the accuracy of pretreatment and instrumental analyses.
  • The impact of chemicals on the ecosystem has been measured in ecotoxicity studies using typical aquatic species of the three trophic levels, i.e., algae (phytoplankton), daphnia, and fish (e. g. medaka fish). A-TERAM aims to more accurately evaluate the effects on the ecosystem by incorporating ecological factors such as the life history of these species and the ecological interactions between species into the model.
  • The environmental quality standards (EQSs) are established and revised by the Ministry of the Environment, Japan. This website compiles references regarding the establishment and revision of EQSs and related items.

Atomospheric Environment

Water / Soil Environment

  • This database provides water quality and aquatic organism data of Lake Kasumigaura, which has been monitored for more than 40 years since the establishment of NIES.
