Abstract

The ADMER was designed to estimate the long-term average spatiotemporal distribution of the concentrations and depositions of chemicals in a comparatively wide region into which the substances are continuously discharged. The concentrations for a 5 x 5 km square grid spatial resolution of 6 time zones (i.e., 4 hours average) for a month are available. 

The ADMER includes some useful functions for the calculation and the exposure and risk assessment, which is for compiling meteorological data and making up gridded emission data for the simulation, and for analyzing the calculation results by such means as visualizing the calculation results using several kind of maps, charts and graphs, and estimating the size and location of the populations who are exposed to chemicals. 

The model has been well verified. The results of the ADMER in the major urban area (Kanto, Kansai and Tokai area) of Japan fit the measured data of the nitrogen oxides (NOx). The version 0.8 beta of ADMER, which works only in the Kanto area of Japan, has been publicly available since October 1st, 2002. 

The version 1.0 of ADMER, which works all over Japan, will be available in the middle of 2003. Anybody can get and use it with no cost. We also have a future plan to develop the next system for all regions, not only in Japan.
