| DUST STORM RESPONSE | |||
| *Dust storm, yellow sand or 'Kosa' is a unique emergency situation that is common to Korea, China and Japan | |||
| *How each country respond to emergency situations brought about by dust storms would also be applicable to how each of the country would respond to emergency air pollution situation. | |||

| Type of response | China | Japan | Korea |
| Year started reporting | Has been included in meteorological report since 2007. | Has been releasing information since 2004. | Performs Kosa forecasts since 2002 |
| Short term forcasting | Uses satellite images to mopnitor the movement of dust | Japan Meteorological Administration (JMA) provides a distribution map of points near Japan where Kosa has been observed | (Korea Meteorological Administration), KMA analyses airborne dust and weather satellite images of Kosa originating from source areas |
| Next day forecast are available. | monitors horizontal distribution of Kosa | ||
| Short term forecast and warnings, medium term forecast and seasonal outlooks | predicts passage over Korea | ||
| Long term forecasting and monitoring | no long term forecasting reported to public | JMA also provides a map predicting the distribution of Kosa based on forecasting model. | predicts deposition of sand based on predicted airflow and atmospheric pressure patterns. |
| monitors the density of PM10 and PM2.5 | |||
| KMA uses data transfer system that shares information in real time (5-min intervals) | |||
| applies real time data to the Kosa forecast/warning system in its weather data system | |||
