A Probabilistic Precipitation Model for the Prediction of Long Range Transport of Acidic Species in East Asia

Acid deposition is one of the most important environmental issues in East Asia including Japan. The long range transport of acidic species from Asian continent to Japan islands cause large amount of acid deposition especially in winter. These phenomena are strongly affected by the precipitation on the sea, however, it is not easy to get enough information on it. This study aims to develop a sim...

Long-Range Transport of SO2 from Continental Asia to Northeast Asia and the Northwest Pacific Ocean: Flow Rate Estimation Using OMI Data, Surface in Situ Data, and the HYSPLIT Model

This present study suggests a method to calculate the SO2 flow rate from a source area to receptor areas on a regional scale using Ozone Monitoring Instrument (OMI) SO2 products, surface in situ SO2 data, and the hybrid single particle Lagrangian integrated trajectory (HYSPLIT) model. The method was implemented to calculate the SO2 flow rate from continental Asia to northeast Asia and the North...

Seasonal Variation of Nitrate Concentration and Its Direct Radiative Forcing over East Asia

This study investigated the seasonal variation of nitrate concentration and its radiative forcing over East Asia by using an online-coupled regional climate model. Comparison with a series of in-situ observations from Acid Deposition Monitoring Network in East Asia (EANET) and China demonstrated a good skill of the model in reproducing the magnitude and seasonality of nitrate concentration acro...

Economic Relations of Japan with Iran and Saudi Arabia -A Comparative Study

This study aims at comparing the economic relations of Japan with Iran and with Saudi Arabia. The comparison of these two relations is important as Iran and Saudi Arabia are leading exporters and Japan is a large importer of crude oil in the world. After a brief overview of the history of these two relations, the criteria of trade complementarity, i.e. Trade Potential Naive Assessment, Cosine M...
